Efficient Channel Assignment Schemes In 802.11 WLAN

A wireless local area network (LAN) is a flexible data communications system implemented as an extension to, or as an alternative for, a wired LAN. Wireless Local Area Networks (WLANs) are having tremendous growth & becoming increasingly popular. The planning of wireless local area network (WLAN) infrastructures that supply large buildings or areas requires the consideration of many aspects (coverage, different traffic densities, interference, cost minimization, network throughput) and therefore is a difficult task if done manually. The performance of WLAN can be greatly improved by efficient channel assignment. This paper presents a survey on efficient channel assignment algorithms in WLAN�s. The survey is concluded with various research issues open for further study.
