Abstract

The IEEE 802.11 wireless LAN (WLAN) has emerged as one of the prevailing wireless technologies for multimedia applications. The wireless technologies are expected to experience a considerable growth in near future. However, while the multimedia applications require some QoS support such as guaranteed bandwidth and bounded delay, 802.11 does not support QoS. Currently IEEE 802.11 group is working on a new QoS-enhanced standard: IEEE 802.11e which propose to improve the performance of wireless LAN. This paper investigates the performance of the original IEEE 802.11 Distributed Coordination Function (DCF), the IEEE 802.11e Enhanced DCF (EDCF) and Adaptive EDCF using contention windows adjustment method. Simulation results show that the original IEEE 802.11 DCF cannot handle service differentiation and QoS guarantee for time-bounded application showing increased in delay. Moreover, the Adaptive EDCF obtains up to 16% improvement of the throughput compared to the IEEE 802.11 DCF.
