Multimedia Capacity Analysis of the IEEE 802.11e Contention-Based Infrastructure Basic Service Set

We propose a novel and simple multimedia capacity analysis framework for the IEEE 802.11e Enhanced Distributed Channel Access (EDCA) function. We design a simple model- based admission control scheme which is based on the accurate queue utilization ratio we calculate by appropriately weighing the service time predictions of our previously developed saturation cycle time model for different number of active stations. We show that the proposed call admission control algorithm maintains satisfactory user-perceived quality for coexisting voice and video connections in an infrastructure Basic Service Set (BSS) and does not present over- or under-admission problems of previously proposed models in the literature.
