As one of the fastest growing wireless access technologies, Wireless LANs (WLANs) must evolve to support adequate degrees of service differentiation. Unfortunately, current WLAN standards like IEEE 802.11 Distributed Coordination Function (DCF) lack this ability. Work is in progress to define an enhanced version capable of supporting QoS for multimedia traffic at the MAC layer. This paper aims at gaining insight into two mechanisms to differentiate among traffic categories, i.e., scaling the minimum contention window size and the length of the packet payload according to the priority of each traffic flow. The paper proposes an analysis model to compute the throughput and packet transmission delays.
