A complete and accurate analytical model for 802.11e EDCA under different traffic conditions

Abstract

In this paper, we propose a complete analytical model for the 802.11e enhanced distributed channel access (EDCA) under different traffic conditions; it outperforms almost all existing models. Based on the proposed model, the achievable throughput and access delay of each EDCA access category are given. Simulation is performed to demonstrate that our model provides a high degree of accuracy.
