A new admission control scheme for the overlapping BSS issues in the 802.11 WLANS

In this paper, a new admission control scheme is presented based on the proportional admission control scheme of the IEEE802.11aa to solve the problems in the 802.11 WLANS. Quality of service (QoS) and throughput are the most significant questions in the 802.11 WLANS especially when the bandwidth is scare. In the Overlapping Basic Service Set (OBSS), we need to face many problems such as the high collision rate, long time delay, low throughput and so forth. So we propose the admission control scheme to work out these questions. This admission control scheme is aimed at improving the throughput simultaneously guaranteeing the Quality of Service (QoS). Our simulation results prove that it can successfully give a high throughput and preserve relatively a low packet loss rate at a high system load.
