摘要
In this paper, we first present our recent work on the non-saturation modelling and performance analysis for IEEE 802.11 Distributed Coordination Function. We extended the previous work and developed a model capable of reflecting the non-saturation condition. Employing the model, by introducing a concept of equivalent competing entity, we designed a measurement-aided model-based call admission control scheme for IEEE 802.11e WLANs Contention-based Channel Access Enhanced Distributed Coordination Function (EDCF) to provide guaranteed throughput Quality of Service (QoS) in a statistical sense. Extensive numerical and simulation results are provided.
