Abstract
Recently, the IEEE 802.11 working group has announced a new distributed MAC called EDCF to provide service differentiation among traffic classes. With the increasing demand for supporting Quality of Service in IEEE 802.11 wireless LANs, the EDCF is now attracting many researchers' attention due to its practical worth as a standard mechanism. In this paper, we focus on the analytical approach to evaluate the performance of the EDCF. An analytical model is developed to estimate the throughput of the EDCF in saturation (asymptotic) conditions. Extensive simulation studies have been carried out for the validation of the analysis, and they show that it estimates the throughput of the EDCF accurately By utilizing the analytical model, we evaluate the performance of the EDCF. Specifically, we concentrate on discovering the characteristics of the EDCF Parameters, such as CW/Sub min/, CW/Sub max/ and AIFS, in the way that they influence on the performance of the EDCF.
