{"title":"Heterogeneity-Aware Load Balancing for Multimedia Access over Wireless LAN Hotspots","authors":"Yen-Cheng Chen, Gong-Da Fang","volume":37,"journal":"International Journal of Electronics and Communication Engineering","pagesStart":62,"pagesEnd":71,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/1426","abstract":"Wireless LAN (WLAN) access in public hotspot areas\r\nbecomes popular in the recent years. Since more and more multimedia\r\ninformation is available in the Internet, there is an increasing demand\r\nfor accessing multimedia information through WLAN hotspots.\r\nCurrently, the bandwidth offered by an IEEE 802.11 WLAN cannot\r\nafford many simultaneous real-time video accesses. A possible way to\r\nincrease the offered bandwidth in a hotspot is the use of multiple access\r\npoints (APs). However, a mobile station is usually connected to the\r\nWLAN AP with the strongest received signal strength indicator (RSSI).\r\nThe total consumed bandwidth cannot be fairly allocated among those\r\nAPs. In this paper, we will propose an effective load-balancing scheme\r\nvia the support of the IAPP and SNMP in APs. The proposed scheme is\r\nan open solution and doesn-t need any changes in both wireless stations\r\nand APs. This makes load balancing possible in WLAN hotspots,\r\nwhere a variety of heterogeneous mobile devices are employed.","references":"[1] IEEE 802.11 WG, \"IEEE 802.11 Standard for Wireless LAN Medium\r\nAccess Control (MAC) and Physical Layer (PHY) Specifications,\" IEEE\r\nStandard, 1999.\r\n[2] Y.
