Abstract--We propose a novel and simple multimedia capacity
analysis framework for the IEEE 802.11e Enhanced Distributed
Channel Access (EDCA) function. We calculate an accurate
station- and AC-specific queue utilization ratio by appropriately
weighing the service time predictions of our previously developed
saturation cycle time model for different number of active
stations. Based on the calculated queue utilization ratio, we
design a simple model-based admission control scheme. 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.
