Saturation Throughput of IEEE 802.11e EDCA Based on Mean Value Analysis

Overview The IEEE 802.11-based wireless LANs have been widely deployed for local area high-speed data access. The IEEE 802.11e amendment aims at providing QoS provisioning to support real-time multimedia traffic in WLANs. The Enhanced Distributed Channel Access (EDCA) is a QoS extension of the Distributed Coordination Function (DCF) in IEEE 802.11a/b/g. This paper proposes an analytical model to evaluate the saturation throughput of the IEEE 802.11e EDCA. The analytical model is based on the use of mean value analysis. The scheme models accurately the effects of the change of contention window size and AIFS (Arbitration Inter-Frame Space).
