A synthetic model of IEEE 802.11e EDCA

International audienceThis paper proposes a very simple reduced abstract model of the behavior of the EDCA (Enhanced Distributed Channel Access) access mode with respect to an access category under saturation. This model is derived from a Markov chain model of EDCA using reduction techniques. Closed-form expressions of common performance metrics (i.e. mean throughput, mean access delay and packet drop probability of an access category) are given and insight into the potential applications of this model are briefly presented
