Performance Analysis of IEEE 802.11e EDCA under Finite Load in an Error Prone Channel

Abstract : Although the IEEE 802.11e standard including Quality of Service support in WiFi networks was recently approved, it does not increase wireless capacity. In order to optimize wireless resources, it is necessary to model the behavior of the system to assist network planning and deployment. In this article, we propose a Markov chain model for the EDCA access scheme described in IEEE 802.11e. Contrary to existing IEEE 802.11 models, our contribution studies more realistic assumptions since we consider a non-ideal channel moreover in unsaturated mode. The benefits of our model are manifold: we calculate the throughput more precisely, we can study various traffic loads, and finally we can examine various transmission environments.
