Abstract

This work surveys routing protocols employed in Wireless local area Network. There are many applications of wireless LANS. The applications embrace in-home networks, campus-sized networks, complete mobile networks on airplanes and trains. Wireless local area Network (WLAN) hot-spots are created in restaurants and hotels and users can access the web from these hot-spots. Most of the time these public networks do not need a password to join the network. Different WLAN hot spots need registration and/or registration fee to access the network. The state of the system in such cases is not static and can change which ends into an amendment in physical and logical topologies used. The convergence by a typical routing protocol is required to handle the problem. This work reviews a number of the quality routing protocols in terms of their characteristic, practicality, economical route discovery mechanisms and comparison of their several merits and demerits in Wireless local area Network. The protocols are classified as a table driven (proactive), reactive (on-demand), power aware, hierarchical and geographical multicast routing protocols.
