An efficient admission control for IEEE 802.11 networks based on throughput analyses of (un)saturated channel
This paper presents a novel analytical model and an efficient admission control algorithm for IEEE 802.11 DCF access mechanism. In contrast to the previous approaches that only analyzed the saturated status of IEEE 802.11 networks, both saturated and unsaturated states of network are analyzed and the impacts of error-frame rate and retransmission limit are also taken into account based on an improved Markov chain model. Taking the throughput difference between saturated and unsaturated states as the residual bandwidth, an efficient admission control algorithm is designed to utilize the network resources effectively. Extensive simulation data demonstrate that the admission control algorithm is efficient and can make the effective utilization of network resources.
