The IEEE 802.11e Enhanced Distributed Channel Access (EDCA) protocol allocates multiple Access Categories (ACs) with different priorities, inter-frame spaces, and contention window sizes in order to support differentiated Quality-of-Service (QoS) in multimedia Wireless Local Area Networks (WLANs). This paper presents an improved Medium Access Control (MAC) scheme to enhance the QoS of WLANs based on the idea of using the different increasing functions for each AC to enlarge the size of contention window in the case of transmission collision. The performance of this improved scheme in the presence of wireless multimedia applications is extensively investigated and compared with the original EDCA using the well-known network simulator NS-2. The results reveal that this scheme is able to achieve higher throughput and medium utilization as well as lower access delay than the EDCA protocol. Moreover, it provides a good prioritization level between multiple ACs.
