Abstract :
IEEE 802.11 specification is used in deployment of WLANs. Medium Access Control of Data link layer uses mechanism called DCF to access the wireless channel. Among the major QoS issues in DCF is the lack of analyzing the current network situation for adjusting the contention window for back off procedure. In this paper, we present a novel algorithm for computing the value of contention window size. The algorithm proposed gives a increased throughput and PDR over the traditional Binary Exponential Back off (BEB) of DCF function.
