Abstract

IEEE 802.11e has been heavily researched with regard to support the Quality of Service (QoS) in wireless LAN environments. The Enhanced Distributed Coordination Function (EDCF) mechanism of IEEE 802.11e has several control parameters for QoS provision, such as minimum/maximum contention window (CW min /CW max ), retry limit, Arbitration Inter Frame Space (AIFS), and so on. Through varying of these parameters, differentiated services can be provided to different priority classes, in terms of throughput, packet loss rate, and delay. The parameters of the IEEE 802.11e EDCF mechanism that have the greatest effect on QoS are investigated in this paper. Especially, Proportional Throughput Differentiation Service (PTDS) is proposed through mathematical analysis for proportional service differentiation between adjacent priority classes and proper setting of control parameters. Finally, the minimum contention window size is confirmed to have the greatest effect with regard to throughput. The validation of PTDS is validated with well-known network simulator, NS-2.
