Wireless LANs (WLANs) are one of the fastest growing wireless access technologies. Unfortunately, since they were developed to closely match existing wired LANs, the popular IEEE 802.11 standards have several problems in providing Quality of Service (QoS) to stations. Importantly, especially for real-time multimedia services, they do not define support for traffic prioritization or upper bound delay guarantees. The IEEE 802.11e standard is being developed to overcome these drawbacks. In this paper, we give an overview of the Medium Access Control (MAC) enhancements found in the current 802.11e draft specification. The standard defines two new mechanisms for QoS support, namely the Enhanced Distributed Coordination Function (EDCF) and the Hybrid Coordination Function (HCF).
