Abstract
In this paper, we present a measurement-assisted model- based distributed admission control mechanism (MM-DAC) to provide statistical QoS delay guarantees in the contention-based channel access of the legacy 802.11 WLANS in a single hop scenario. The admission control is added to our scheduler-based architecture which uses p-persistent 802.11 MAC as the basic channel access mechanism. The MM-DAC scheme uses delay predictions in making admission decisions and our simulation tests showed that it successfully meets the delay requirements of admitted flows and preserves low packet drop rates at high system loads.
