In this paper, we propose an improved discrete three- dimension Markov chain model to describe the IEEE 802.11e EDCA characteristics. The unifying model is designed to compute the sustained probabilistic prop- erties for each prioritized AC under saturation condi- tion. In this framework, we consider elaborately the modified the AIFS and backoff co-operation process in EDCA defined by the IEEE 802.11e standard rather than those previous literature which concern the origi- nal EDCF protocol defined by draft version. Compre- hensive simulation studies validate our analytical ap- proach is quite fair in predicting the system saturation throughput. Ultimately, our model and analysis can provide an in-depth understanding and insights into the IEEE 802.11e EDCA features.
