With the increasing demand of wireless local area networks, the support of differentiated Quality of Service (QoS) has become one of the critical issues on IEEE 802.11 medium access control protocols. To support the differentiated QoS requirements, IEEE 802.11e has been standardized. IEEE 802.11e defines Enhanced Distributed Channel Access (EDCA) for access mechanism, which is a contention based channel access method and delivers traffic based on differentiated access categories for the support of QoS. This paper introduces a three dimensional Markov chain model to evaluate the performance of IEEE 802.11e EDCA mechanism with an arbitrary number of different access categories. The proposed analytical model captures the major QoS specific features in the IEEE 802.11e EDCA and hence can provide a numerical approach to pick the set of EDCA parameter values to meet the QoS requirements of each access category. The results of our proposed analytical model are verified using simulations.
