Wireless mesh networks, consisting of mesh routers and mesh clients are very robust, reliable and easily maintained networks. This paper is based on IEEE 802.11 standard amendment IEEE 802.11s specific for mesh topology based networks to improve the connectivity and coverage. It aims to control the shared medium access among the stations using Distributed Coordination Function (DCF) MAC protocol for reducing collisions and delays, thereby increasing throughput of the network. The actual Binary Exponential Back off (BEB) algorithm as implemented in IEEE 802.11 resets the contention window to its least value after an acknowledged transmission.
