“…[8] and [9] respectively present a call admission control (CAC) scheme for one-hop network in heterogeneous environment to protect the QoS. [n [10], they propose a joint uplink and downlink admission control scheme to mitigate the traffic load by setting an adaptive connection threshold. Then, IEEE802.11aa [4] figures out the problems of the Overlapping Basic service set (OBSS) from two perspectives that are channel select and admission control.…”

In this paper, a new admission control scheme is presented based on the proportional admission control scheme of the IEEES02.11aa to solve the problems in the S02.11 WLANS.Quality of service (QoS) and throughput are the most significant questions in the S02.11 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.
