It is expected to be the next generation wireless communication technology according to its inherent characteristics like: an increased bandwidth, a high data rate, a data transmission security, an immunity to interference, and an unregulated spectrum etc. Optical space links are the best choice for the classical communication schemes due to its distinctive properties; high frequency, small antenna diameter and lowest transmitted power, which are critical factors to define a space communication. This paper discusses the development of free space technology and analyses the parameters and factors to establish a reliable intersatellite links using an optical signal to exchange data between satellites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20intersatellite%20links" title="optical intersatellite links">optical intersatellite links</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20wireless%20communications" title=" optical wireless communications"> optical wireless communications</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20space%20optical%20communications" title=" free space optical communications"> free space optical communications</a>, <a href="https://publications.waset.org/abstracts/search?q=next%20generation%20wireless%20communication" title=" next generation wireless communication"> next generation wireless communication</a> </p> <a href="https://publications.waset.org/abstracts/46827/study-and-analysis-of-optical-intersatellite-links" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46827.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">451</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3490</span> Investigation of Cascade Loop Heat Pipes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nandy%20Putra">Nandy Putra</a>, <a href="https://publications.waset.org/abstracts/search?q=Atrialdipa%20Duanovsah"> Atrialdipa Duanovsah</a>, <a href="https://publications.waset.org/abstracts/search?q=Kristofer%20Haliansyah"> Kristofer Haliansyah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research is to design a LHP with low thermal resistance and low condenser temperature. A Self-designed cascade LHP was tested by using biomaterial, sintered copper powder, and aluminum screen mesh as the wick. Using pure water as the working fluid for the first level of the LHP and 96% alcohol as the working fluid for the second level of LHP, the experiments were run with 10W, 20W, and 30W heat input. Experimental result shows that the usage of biomaterial as wick could reduce more temperature at evaporator than by using sintered copper powder and screen mesh up to 22.63% and 37.41% respectively. The lowest thermal resistance occurred during the usage of biomaterial as wick of heat pipe, which is 2.06 <sup>o</sup>C/W.

The combination of satellites and 5G architecture allows consumers to access all next-generation services anytime, anywhere, including scenarios, like traveling to remote areas (without coverage). Nevertheless, this solution faces several challenges, such as a significant propagation delay, Doppler frequency shift, and high Peak-to-Average Power Ratio (PAPR), causing signal distortion due to the non-linear saturation of the High-Power Amplifier (HPA). To compensate for HPA non-linearity in 5G satellite transmission, an efﬁcient pre-distorter scheme using Neural Networks (NN) is proposed. To assess the proposed NN pre-distorter, two types of HPA were investigated: Travelling Wave Tube Amplifier (TWTA) and Solid-State Power Amplifier (SSPA). The results show that the NN pre-distorter design presents EVM improvement by 95.26%. NMSE and ACPR were reduced by -43,66 dB and 24.56 dBm, respectively. Moreover, the system suffers no degradation of the Bit Error Rate (BER) for TWTA and SSPA amplifiers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=satellites" title="satellites">satellites</a>, <a href="https://publications.waset.org/abstracts/search?q=5G" title=" 5G"> 5G</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=HPA" title=" HPA"> HPA</a>, <a href="https://publications.waset.org/abstracts/search?q=TWTA" title=" TWTA"> TWTA</a>, <a href="https://publications.waset.org/abstracts/search?q=SSPA" title=" SSPA"> SSPA</a>, <a href="https://publications.waset.org/abstracts/search?q=EVM" title=" EVM"> EVM</a>, <a href="https://publications.waset.org/abstracts/search?q=NMSE" title=" NMSE"> NMSE</a>, <a href="https://publications.waset.org/abstracts/search?q=ACPR" title=" ACPR"> ACPR</a> </p> <a href="https://publications.waset.org/abstracts/170447/hpa-pre-distorter-based-on-neural-networks-for-5g-satellite-communications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170447.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3488</span> Implementation of Distributed Randomized Algorithms for Resilient Peer-to-Peer Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Richard%20Tanaka">Richard Tanaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Zhu"> Ying Zhu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies a few randomized algorithms in application-layer peer-to-peer networks. The significant gain in scalability and resilience that peer-to-peer networks provide has made them widely used and adopted in many real-world distributed systems and applications. The unique properties of peer-to-peer networks make them particularly suitable for randomized algorithms such as random walks and gossip algorithms. Instead of simulations of peer-to-peer networks, we leverage the Docker virtual container technology to develop implementations of the peer-to-peer networks and these distributed randomized algorithms running on top of them. We can thus analyze their behaviour and performance in realistic settings. We further consider the problem of identifying high-risk bottleneck links in the network with the objective of improving the resilience and reliability of peer-to-peer networks. We propose a randomized algorithm to solve this problem and evaluate its performance by simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distributed%20randomized%20algorithms" title="distributed randomized algorithms">distributed randomized algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=peer-to-peer%20networks" title=" peer-to-peer networks"> peer-to-peer networks</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20container%20technology" title=" virtual container technology"> virtual container technology</a>, <a href="https://publications.waset.org/abstracts/search?q=resilient%20networks" title=" resilient networks"> resilient networks</a> </p> <a href="https://publications.waset.org/abstracts/133527/implementation-of-distributed-randomized-algorithms-for-resilient-peer-to-peer-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133527.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">224</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3487</span> ZigBee Wireless Sensor Nodes with Hybrid Energy Storage System Based on Li-Ion Battery and Solar Energy Supply</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Chi%20Chang">Chia-Chi Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chuan-Bi%20Lin"> Chuan-Bi Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia-Min%20Chan"> Chia-Min Chan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most ZigBee sensor networks to date make use of nodes with limited processing, communication, and energy capabilities. Energy consumption is of great importance in wireless sensor applications as their nodes are commonly battery-driven. Once ZigBee nodes are deployed outdoors, limited power may make a sensor network useless before its purpose is complete. At present, there are two strategies for long node and network lifetime. The first strategy is saving energy as much as possible. The energy consumption will be minimized through switching the node from active mode to sleep mode and routing protocol with ultra-low energy consumption. The second strategy is to evaluate the energy consumption of sensor applications as accurately as possible. Erroneous energy model may render a ZigBee sensor network useless before changing batteries. In this paper, we present a ZigBee wireless sensor node with four key modules: a processing and radio unit, an energy harvesting unit, an energy storage unit, and a sensor unit. The processing unit uses CC2530 for controlling the sensor, carrying out routing protocol, and performing wireless communication with other nodes. The harvesting unit uses a 2W solar panel to provide lasting energy for the node. The storage unit consists of a rechargeable 1200 mAh Li-ion battery and a battery charger using a constant-current/constant-voltage algorithm. Our solution to extend node lifetime is implemented. Finally, a long-term sensor network test is used to exhibit the functionality of the solar powered system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZigBee" title="ZigBee">ZigBee</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-ion%20battery" title=" Li-ion battery"> Li-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20panel" title=" solar panel"> solar panel</a>, <a href="https://publications.waset.org/abstracts/search?q=CC2530" title=" CC2530 "> CC2530 </a> </p> <a href="https://publications.waset.org/abstracts/10028/zigbee-wireless-sensor-nodes-with-hybrid-energy-storage-system-based-on-li-ion-battery-and-solar-energy-supply" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10028.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">382</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3486</span> MEMS based Vibration Energy Harvesting: An overview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Prabhudesai">Gaurav Prabhudesai</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaurya%20Kaushal"> Shaurya Kaushal</a>, <a href="https://publications.waset.org/abstracts/search?q=Pulkit%20Dubey"> Pulkit Dubey</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20D.%20Pant"> B.

The power drivers or the power pack, electrically driving these modules have also reduced in proportion. Normally, the power packs in these mobile or fixed systems are batteries, rechargeable or non-rechargeable, which need regular replacement or recharging. Another approach to power these modules is to utilize the ambient energy available for electrical driving to make the system self-sustained. The current paper presents an overview of the different MEMS (Micro-Electro-Mechanical Systems) based techniques used for the harvesting of vibration energy to electrically drive a WSN (wireless sensor network) or a mobile module. This kind of system would have enormous applications, the most significant one, may be in cell phones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20harvesting" title="energy harvesting">energy harvesting</a>, <a href="https://publications.waset.org/abstracts/search?q=WSN" title=" WSN"> WSN</a>, <a href="https://publications.waset.org/abstracts/search?q=MEMS" title=" MEMS"> MEMS</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectrics" title=" piezoelectrics"> piezoelectrics</a> </p> <a href="https://publications.waset.org/abstracts/22297/mems-based-vibration-energy-harvesting-an-overview" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22297.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">507</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3485</span> Review on Implementation of Artificial Intelligence and Machine Learning for Controlling Traffic and Avoiding Accidents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neha%20Singh">Neha Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Shristi%20Singh"> Shristi Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accidents involving motor vehicles are more likely to cause serious injuries and fatalities. It also has a host of other perpetual issues, such as the regular loss of life and goods in accidents. To solve these issues, appropriate measures must be implemented, such as establishing an autonomous incident detection system that makes use of machine learning and artificial intelligence. In order to reduce traffic accidents, this article examines the overview of artificial intelligence and machine learning in autonomous event detection systems. The paper explores the major issues, prospective solutions, and use of artificial intelligence and machine learning in road transportation systems for minimising traffic accidents. There is a lot of discussion on additional, fresh, and developing approaches that less frequent accidents in the transportation industry. The study structured the following subtopics specifically: traffic management using machine learning and artificial intelligence and an incident detector with these two technologies. The internet of vehicles and vehicle ad hoc networks, as well as the use of wireless communication technologies like 5G wireless networks and the use of machine learning and artificial intelligence for the planning of road transportation systems, are elaborated. In addition, safety is the primary concern of road transportation. Route optimization, cargo volume forecasting, predictive fleet maintenance, real-time vehicle tracking, and traffic management, according to the review's key conclusions, are essential for ensuring the safety of road transportation networks. In addition to highlighting research trends, unanswered problems, and key research conclusions, the study also discusses the difficulties in applying artificial intelligence to road transport systems. Planning and managing the road transportation system might use the work as a resource. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=incident%20detector" title=" incident detector"> incident detector</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20transport%20systems" title=" road transport systems"> road transport systems</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20management" title=" traffic management"> traffic management</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20incident%20detection" title=" automatic incident detection"> automatic incident detection</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a> </p> <a href="https://publications.waset.org/abstracts/159822/review-on-implementation-of-artificial-intelligence-and-machine-learning-for-controlling-traffic-and-avoiding-accidents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159822.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3484</span> Secured Cancer Care and Cloud Services in Internet of Things /Wireless Sensor Network Based Medical Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adeniyi%20Onasanya">Adeniyi Onasanya</a>, <a href="https://publications.waset.org/abstracts/search?q=Maher%20Elshakankiri"> Maher Elshakankiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the Internet of Things (IoT) has constituted a driving force of modern technological advancement, and it has become increasingly common as its impacts are seen in a variety of application domains, including healthcare. IoT is characterized by the interconnectivity of smart sensors, objects, devices, data, and applications. With the unprecedented use of IoT in industrial, commercial and domestic, it becomes very imperative to harness the benefits and functionalities associated with the IoT technology in (re)assessing the provision and positioning of healthcare to ensure efficient and improved healthcare delivery. In this research, we are focusing on two important services in healthcare systems, which are cancer care services and business analytics/cloud services.

Specific emitter identification (SEI) is an vital part of wireless communication security as a technique to identify the unique transmitters. In this paper, a SEI method based on multiscale dispersion entropy (MDE) and refined composite multiscale dispersion entropy (RCMDE) is proposed. The algorithms of MDE and RCMDE are used to extract features for identification of five wireless devices and cross-validation support vector machine (CV-SVM) is used as the classifier. The experimental results show that the total identification accuracy is 99.3%, even at low signal-to-noise ratio(SNR) of 5dB, which proves that MDE and RCMDE can describe the communication signal series well. In addition, compared with other methods, the proposed method is effective and provides better accuracy and stability for SEI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-validation%20support%20vector%20machine" title="cross-validation support vector machine">cross-validation support vector machine</a>, <a href="https://publications.waset.org/abstracts/search?q=refined%20com-%20posite%20multiscale%20dispersion%20entropy" title=" refined com- posite multiscale dispersion entropy"> refined com- posite multiscale dispersion entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20emitter%20identification" title=" specific emitter identification"> specific emitter identification</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20signal" title=" transient signal"> transient signal</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20communication%20device" title=" wireless communication device"> wireless communication device</a> </p> <a href="https://publications.waset.org/abstracts/105514/specific-emitter-identification-based-on-refined-composite-multiscale-dispersion-entropy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">132</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3482</span> Impact of Social Media on Content of Saudi Television News Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majed%20Alshaibani">Majed Alshaibani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social media has emerged as a serious contender to TV news networks in Saudi Arabia. The growing usage of social media as a source of news and information has led to significant impact on the content presented by the news networks in Saudi Arabia. This study explored the various ways in which social media has influenced content aired on Saudi news networks. Data were collected by using semi structured interviews with 13 journalists and content editors working for four Saudi TV news networks and six senior academic experts on TV and media teaching in Saudi universities. The findings of the study revealed that social media has affected four aspects of the content on Saudi TV news networks. As a result the content aired on Saudi news networks is more neutral, real time, diverse in terms of sources and includes content on broader subjects and from different parts of the world. This research concludes that social media has contributed positively and significantly to improving the content on Saudi TV news networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TV%20news%20networks" title="TV news networks">TV news networks</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=media%20content" title=" media content"> media content</a> </p> <a href="https://publications.waset.org/abstracts/125622/impact-of-social-media-on-content-of-saudi-television-news-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125622.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3481</span> Deep Learning-Based Channel Estimation for Reconfigurable Intelligent Surface-Assisted Unmanned Aerial Vehicle-Enabled Wireless Communication System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Getaneh%20Berie%20Tarekegn">Getaneh Berie Tarekegn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wireless communication via unmanned aerial vehicles (UAVs) has drawn a great deal of attention due to its flexibility in establishing line-of-sight (LoS) communications. However, in complex urban and dynamic environments, the movement of UAVs can be blocked by trees and high-rise buildings that obstruct directional paths. With reconfigurable intelligent surfaces (RIS), this problem can be effectively addressed. To achieve this goal, accurate channel estimation in RIS-assisted UAV-enabled wireless communications is crucial. This paper proposes an accurate channel estimation model using long short-term memory (LSTM) for a multi-user RIS-assisted UAV-enabled wireless communication system.

The shape boundary movement is coupled to the movement of the novel concept of the control nodes via a quasi-1D-linear deformation. Additionally, a second order smoothing step has been integrated to act on the boundary during the mesh movement based on the change in its second derivative. This allows for both linear and non-linear shape transformations dependent on the preference of the user. The domain mesh movement is then coupled to the shape boundary movement via a Delaunay graph mapping. A Modified Cuckoo Search (MCS) algorithm is used for optimisation within the prescribed design space defined by the allowed range of control node displacement. A finite volume compressible NavierStokes solver is used for aerodynamic modelling to predict aerodynamic design fitness. The resulting coupled algorithm is applied to a range of test cases in two dimensions including the design of a subsonic, transonic and supersonic intake and the optimisation approach is compared with more conventional optimisation strategies. Ultimately, the algorithm is tested on a three dimensional wing optimisation case. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesh%20movement" title="mesh movement">mesh movement</a>, <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20shape%20optimization" title=" aerodynamic shape optimization"> aerodynamic shape optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=cuckoo%20search" title=" cuckoo search"> cuckoo search</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20parameterisation" title=" shape parameterisation"> shape parameterisation</a> </p> <a href="https://publications.waset.org/abstracts/42527/computational-aerodynamic-shape-optimisation-using-a-concept-of-control-nodes-and-modified-cuckoo-search" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42527.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3479</span> A New Reliability based Channel Allocation Model in Mobile Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anujendra">Anujendra</a>, <a href="https://publications.waset.org/abstracts/search?q=Parag%20Kumar%20Guha%20Thakurta"> Parag Kumar Guha Thakurta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The data transmission between mobile hosts and base stations (BSs) in Mobile networks are often vulnerable to failure. Thus, efficient link connectivity, in terms of the services of both base stations and communication channels of the network, is required in wireless mobile networks to achieve highly reliable data transmission. In addition, it is observed that the number of blocked hosts is increased due to insufficient number of channels during heavy load in the network. Under such scenario, the channels are allocated accordingly to offer a reliable communication at any given time. Therefore, a reliability-based channel allocation model with acceptable system performance is proposed as a MOO problem in this paper. Two conflicting parameters known as Resource Reuse factor (RRF) and the number of blocked calls are optimized under reliability constraint in this problem. The solution to such MOO problem is obtained through NSGA-II (Non-dominated Sorting Genetic Algorithm). The effectiveness of the proposed model in this work is shown with a set of experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=base%20station" title="base station">base station</a>, <a href="https://publications.waset.org/abstracts/search?q=channel" title=" channel"> channel</a>, <a href="https://publications.waset.org/abstracts/search?q=GA" title=" GA"> GA</a>, <a href="https://publications.waset.org/abstracts/search?q=pareto-optimal" title=" pareto-optimal"> pareto-optimal</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a> </p> <a href="https://publications.waset.org/abstracts/2639/a-new-reliability-based-channel-allocation-model-in-mobile-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2639.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3478</span> Energy-Efficient and Low-Latency Framework for Unmanned Aerial Vehicles-Assisted Wireless Sensor Networks Using Multi-Agent Deep Reinforcement Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mesfin%20Leranso%20Betalo">Mesfin Leranso Betalo</a>, <a href="https://publications.waset.org/abstracts/search?q=Getaneh%20Berie%20Tarekegn"> Getaneh Berie Tarekegn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ultra-dense wireless sensor networks (WSNs) are vital for numerous applications, including smart agriculture systems supported by fifth-generation (5G) and beyond technologies. These WSNs rely on multiple unmanned aerial vehicles (UAVs) to gather data from sensor nodes (SNs) and transmit it to a central controller for processing. UAVs also enhance network coverage and provide essential resources to SNs across large geographical regions. This flexibility makes UAV-assisted WSNs a suitable choice for meeting the stringent demands of smart agriculture, such as real-time data transmission and remote monitoring. Despite these advantages, several challenges persist, including the limited battery capacity of UAVs, restricted transmission power, and energy limitations of SNs. These constraints hinder efficient data collection and task execution, leading to suboptimal resource management in smart agricultural systems. To address these issues, this paper proposes a unified framework for UAV task scheduling, trajectory optimization, and resource sharing in multi-UAV-assisted WSNs for smart agricultural monitoring. The framework schedules UAV charging, data collection, and landing activities while enabling UAVs to share energy with SNs. The primary objective of this framework is to minimize energy consumption and network latency, ensuring timely and efficient data collection. The problem is formulated as a multi-objective, non-convex optimization task and redefined as a Markov Decision Process (MDP), which is solved using a multi-agent deep reinforcement learning (MADRL) algorithm. Simulation results demonstrate that the proposed MADRL approach achieves significant energy savings, reducing energy consumption costs by 71.92%, 78.02%, and 79.9% compared to deep Q-network, greedy, and mixed-integer linear programming (MILP) approaches, respectively <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UAV-assisted%20wireless%20sensor%20networks" title="UAV-assisted wireless sensor networks">UAV-assisted wireless sensor networks</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20optimization" title=" energy optimization"> energy optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-agent%20deep%20reinforcement%20learning" title=" multi-agent deep reinforcement learning"> multi-agent deep reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=task%20scheduling" title=" task scheduling"> task scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=trajectory%20planning" title=" trajectory planning"> trajectory planning</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20sharing" title=" resource sharing"> resource sharing</a> </p> <a href="https://publications.waset.org/abstracts/198599/energy-efficient-and-low-latency-framework-for-unmanned-aerial-vehicles-assisted-wireless-sensor-networks-using-multi-agent-deep-reinforcement-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/198599.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3477</span> Computational Fluid Dynamics Simulation Study of Flow near Moving Wall of Various Surface Types Using Moving Mesh Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khizir%20Mohd%20Ismail">Khizir Mohd Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Jun%20Lim"> Yu Jun Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tshun%20Howe%20Yong"> Tshun Howe Yong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of flow behavior in an enclosed volume using Computational Fluid Dynamics (CFD) has been around for decades. However, due to the knowledge limitation of adaptive grid methods, the flow in an enclosed volume near the moving wall using CFD is less explored. A CFD simulation of flow in an enclosed volume near a moving wall was demonstrated and studied by introducing a moving mesh method and was modeled with Unsteady Reynolds-Averaged Navier-Stokes (URANS) approach. A static enclosed volume with controlled opening size in the bottom was positioned against a moving, translational wall with sliding mesh features. Controlled variables such as smoothed, crevices and corrugated wall characteristics, the distance between the enclosed volume to the wall and the moving wall speed against the enclosed chamber were varied to understand how the flow behaves and reacts in between these two geometries. These model simulations were validated against experimental results and provided result confidence when the simulation had shown good agreement with the experimental data. This study had provided better insight into the flow behaving in an enclosed volume when various wall types in motion were introduced within the various distance between each other and create a potential opportunity of application which involves adaptive grid methods in CFD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moving%20wall" title="moving wall">moving wall</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20grid%20methods" title=" adaptive grid methods"> adaptive grid methods</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20mesh%20method" title=" moving mesh method"> moving mesh method</a> </p> <a href="https://publications.waset.org/abstracts/110284/computational-fluid-dynamics-simulation-study-of-flow-near-moving-wall-of-various-surface-types-using-moving-mesh-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110284.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3476</span> Proposal of Commutation Protocol in Hybrid Sensors and Vehicular Networks for Intelligent Transport Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taha%20Bensiradj">Taha Bensiradj</a>, <a href="https://publications.waset.org/abstracts/search?q=Samira%20Moussaoui"> Samira Moussaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hybrid Sensors and Vehicular Networks (HSVN), represent a hybrid network, which uses several generations of Ad-Hoc networks. It is used especially in Intelligent Transport Systems (ITS). The HSVN allows making collaboration between the Wireless Sensors Network (WSN) deployed on the border of the road and the Vehicular Network (VANET). This collaboration is defined by messages exchanged between the two networks for the purpose to inform the drivers about the state of the road, provide road safety information and more information about traffic on the road. Moreover, this collaboration created by HSVN, also allows the use of a network and the advantage of improving another network. For example, the dissemination of information between the sensors quickly decreases its energy, and therefore, we can use vehicles that do not have energy constraint to disseminate the information between sensors. On the other hand, to solve the disconnection problem in VANET, the sensors can be used as gateways that allow sending the messages received by one vehicle to another. However, because of the short communication range of the sensor and its low capacity of storage and processing of data, it is difficult to ensure the exchange of road messages between it and the vehicle, which can be moving at high speed at the time of exchange. This represents the time where the vehicle is in communication range with the sensor. This work is the proposition of a communication protocol between the sensors and the vehicle used in HSVN. The latter has as the purpose to ensure the exchange of road messages in the available time of exchange. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HSVN" title="HSVN">HSVN</a>, <a href="https://publications.waset.org/abstracts/search?q=ITS" title=" ITS"> ITS</a>, <a href="https://publications.waset.org/abstracts/search?q=VANET" title=" VANET"> VANET</a>, <a href="https://publications.waset.org/abstracts/search?q=WSN" title=" WSN"> WSN</a> </p> <a href="https://publications.waset.org/abstracts/54397/proposal-of-commutation-protocol-in-hybrid-sensors-and-vehicular-networks-for-intelligent-transport-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54397.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">368</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3475</span> Survey on Energy Efficient Routing Protocols in Mobile Ad-Hoc Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swapnil%20Singh">Swapnil Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjoy%20Das"> Sanjoy Das</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mobile Ad-Hoc Network (MANET) is infrastructure less networks dynamically formed by autonomous system of mobile nodes that are connected via wireless links.

The main reason being that given the intricacies in the physical structure of a coal mine, only low power WSN nodes can produce accurate surveillance and accident detection data. The work mainly concentrated on designing and simulating various alternate scenarios for a typical mine and comparing them based on the obtained results to arrive at a final design. In the Era of embedded technology, the Zigbee protocols are used in more and more applications. Because of the rapid development of sensors, microcontrollers, and network technology, a reliable technological condition has been provided for our automatic real-time monitoring of coal mine. The underground system collects temperature, humidity and methane values of coal mine through sensor nodes in the mine; it also collects the number of personnel inside the mine with the help of an IR sensor, and then transmits the data to information processing terminal based on ARM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ARM" title="ARM">ARM</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20board" title=" embedded board"> embedded board</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20network%20%28Zigbee%29" title=" wireless sensor network (Zigbee)"> wireless sensor network (Zigbee)</a> </p> <a href="https://publications.waset.org/abstracts/23028/coal-mining-safety-monitoring-using-wsn" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23028.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3472</span> Enhancing Healthcare Delivery in Low-Income Markets: An Exploration of Wireless Sensor Network Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Innocent%20Uzougbo%20Onwuegbuzie">Innocent Uzougbo Onwuegbuzie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Healthcare delivery in low-income markets is fraught with numerous challenges, including limited access to essential medical resources, inadequate healthcare infrastructure, and a significant shortage of trained healthcare professionals. These constraints lead to suboptimal health outcomes and a higher incidence of preventable diseases. This paper explores the application of Wireless Sensor Networks (WSNs) as a transformative solution to enhance healthcare delivery in these underserved regions. WSNs, comprising spatially distributed sensor nodes that collect and transmit health-related data, present opportunities to address critical healthcare needs. Leveraging WSN technology facilitates real-time health monitoring and remote diagnostics, enabling continuous patient observation and early detection of medical issues, especially in areas with limited healthcare facilities and professionals. The implementation of WSNs can enhance the overall efficiency of healthcare systems by enabling timely interventions, reducing the strain on healthcare facilities, and optimizing resource allocation. This paper highlights the potential benefits of WSNs in low-income markets, such as cost-effectiveness, increased accessibility, and data-driven decision-making. However, deploying WSNs involves significant challenges, including technical barriers like limited internet connectivity and power supply, alongside concerns about data privacy and security. Moreover, robust infrastructure and adequate training for local healthcare providers are essential for successful implementation. It further examines future directions for WSNs, emphasizing innovation, scalable solutions, and public-private partnerships. By addressing these challenges and harnessing the potential of WSNs, it is possible to revolutionize healthcare delivery and improve health outcomes in low-income markets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks%20%28WSNs%29" title="wireless sensor networks (WSNs)">wireless sensor networks (WSNs)</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20delivery" title=" healthcare delivery"> healthcare delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=low-Income%20markets" title=" low-Income markets"> low-Income markets</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20patient%20monitoring" title=" remote patient monitoring"> remote patient monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20data%20security" title=" health data security"> health data security</a> </p> <a href="https://publications.waset.org/abstracts/188252/enhancing-healthcare-delivery-in-low-income-markets-an-exploration-of-wireless-sensor-network-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188252.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">47</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3471</span> Optimal Design of Reference Node Placement for Wireless Indoor Positioning Systems in Multi-Floor Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kittipob%20Kondee">Kittipob Kondee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chutima%20Prommak"> Chutima Prommak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose an optimization technique that can be used to optimize the placements of reference nodes and improve the location determination performance for the multi-floor building.

The system tackles the dual challenge of throughput optimization while considering sensor network energy consumption. A unique routing metric has been developed to enable throughput maximization while minimizing energy consumption by utilizing data correlation patterns. The paper introduces a game theoretic framework to address the NP-complete optimization problem inherent in throughput-maximizing correlation-aware routing with energy limitations. By creating an algorithm that blends energy-aware route selection strategies with the best reaction dynamics, this framework provides a local solution. The suggested technique considerably raises the bottleneck throughput for each source in the network while reducing energy consumption by choosing the best routes that strike a compromise between throughput enhancement and energy efficiency. Extensive numerical analyses verify the efficiency of the method. The outcomes demonstrate the significant decrease in energy consumption attained by the energy-efficient relay-augmented bottleneck throughput maximization technique, in addition to confirming the anticipated throughput benefits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlated%20data%20aggregation" title="correlated data aggregation">correlated data aggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20theory" title=" game theory"> game theory</a>, <a href="https://publications.waset.org/abstracts/search?q=relay-augmented%20routing" title=" relay-augmented routing"> relay-augmented routing</a>, <a href="https://publications.waset.org/abstracts/search?q=throughput%20maximization" title=" throughput maximization"> throughput maximization</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title=" wireless sensor networks"> wireless sensor networks</a> </p> <a href="https://publications.waset.org/abstracts/177804/relay-augmented-bottleneck-throughput-maximization-for-correlated-data-routing-a-game-theoretic-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177804.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3469</span> Comparative Analysis of Universal Filtered Multi Carrier and Filtered Orthogonal Frequency Division Multiplexing Systems for Wireless Communications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raja%20Rajeswari%20K">Raja Rajeswari K</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Orthogonal Frequency Division Multiplexing (OFDM), a multi Carrier transmission technique that has been used in implementing the majority of wireless applications like Wireless Network Protocol Standards (like IEEE 802.11a, IEEE 802.11n), in telecommunications (like LTE, LTE-Advanced) and also in Digital Audio & Video Broadcast standards.

A lot of experiments have been carried out to investigate the performance of the proposed ALM algorithm by using different parameter settings, different sampling rates and sampling models. In addition, we compare the proposed ALM algorithm with some existing algorithms in the literature.

Thus, to have a balance between production and consumption, it is necessary at first to increase the number of power plants, lines and transformers, which implies an increase in cost and environmental degradation. As a result, it is now important to have mesh networks and working close to the limits of stability in order to meet these new requirements. The transient stability studies involve large disturbances such as short circuits, loss of work or production group. The consequence of these defects can be very serious, and can even lead to the complete collapse of the network. This work focuses on the regulation means that networks can help to keep their stability when submitted to strong disturbances. The magnetic energy storage-based superconductor (SMES) comprises a superconducting coil short-circuited on it self. When such a system is connected to a power grid is able to inject or absorb the active and reactive power. This system can be used to improve the stability of power systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=short-circuit" title="short-circuit">short-circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20oscillations" title=" power oscillations"> power oscillations</a>, <a href="https://publications.waset.org/abstracts/search?q=multiband%20PSS" title=" multiband PSS"> multiband PSS</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system" title=" power system"> power system</a>, <a href="https://publications.waset.org/abstracts/search?q=SMES" title=" SMES"> SMES</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20stability" title=" transient stability"> transient stability</a> </p> <a href="https://publications.waset.org/abstracts/1367/the-contribution-of-smes-to-improve-the-transient-stability-of-multimachine-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1367.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">463</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3464</span> Design and Analysis of Wireless Charging Lane for Light Rail Transit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Watcharet%20Kongwarakom">Watcharet Kongwarakom</a>, <a href="https://publications.waset.org/abstracts/search?q=Tosaphol%20Ratniyomchai"> Tosaphol Ratniyomchai</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanatchai%20Kulworawanichpong"> Thanatchai Kulworawanichpong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a design and analysis of wireless charging lane system (WCLS) for light rail transit (LRT) by considering the performance of wireless charging, traffic conditions and energy consumption drawn by the LRT system.

The main focus of application are reactors which are wirelessly powered. Due to the promising properties of the propagation of magnetic fields under water we implemented an inductive link with an on/off switched hartley-oscillator as transmitter and an LC-tank as receiver. For this inductive link we used a carrier frequency of 298 kHz. With this system we performed measurements to demonstrate the independence of the magnetic field from water or salty water. In contrast we showed the strongly reduced range of RF-transmitter-receiver systems at higher frequencies (433 MHz and 2.4 GHz) in water and in salty water. For implementing the traceability of the sensors, we performed measurements to show the well defined orientation of the magnetic field of a coil. This information will be used in future work for implementing an inductive link based traceability system for our sensors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensors" title="wireless sensors">wireless sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=photoreactor" title=" photoreactor"> photoreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20illumination" title=" internal illumination"> internal illumination</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20power" title=" wireless power"> wireless power</a> </p> <a href="https://publications.waset.org/abstracts/109796/design-of-wireless-and-traceable-sensors-for-internally-illuminated-photoreactors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109796.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3462</span> A Finite Element Based Predictive Stone Lofting Simulation Methodology for Automotive Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Bisht">Gaurav Bisht</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Rathnakumar"> Rahul Rathnakumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ravikumar%20Duggirala"> Ravikumar Duggirala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Predictive simulations are one of the key focus areas in safety-critical industries such as aerospace and high-performance automotive engineering. The stone-chipping study is one such effort taken up by the industry to predict and evaluate the damage caused due to gravel impact on vehicles. This paper describes a finite elements based method that can simulate the ejection of gravel chips from a vehicle tire. The FE simulations were used to obtain the initial ejection velocity of the stones for various driving conditions using a computational contact mechanics approach. To verify the accuracy of the tire model, several parametric studies were conducted. The FE simulations resulted in stone loft velocities ranging from 0–8 m/s, regardless of tire speed. The stress on the tire at the instant of initial contact with the stone increased linearly with vehicle speed. Mesh convergence studies indicated that a highly resolved tire mesh tends to result in better momentum transfer between the tire and the stone. A fine tire mesh also showed a linearly increasing relationship between the tire forward speed and stone lofting speed, which was not observed in coarser meshes. However, it also highlighted a potential challenge, in that the ejection velocity vector of the stone seemed to be sensitive to the mesh, owing to the FE-based contact mechanical formulation of the problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abaqus" title="abaqus">abaqus</a>, <a
