Abstract
In the recent years Wireless Local Area Networks of the IEEE 802.11 standard experienced an impressing commercial success. The increasing demand for Quality-of-Service is the motivation for extending this standard through the amendment 802.11e. These enhancements introduce a Hybrid Coordination Function to enable the support of Quality-of-Service. The Hybrid Coordination Function defines two medium access mechanisms: the (1) contention-based channel access and (2) the controlled channel access. The contention-based channel access is referred to as Enhanced Distributed Channel Access and is discussed in this paper. 802.11e introduces four Access Categories that define different parameter sets for the Enhanced Distributed Channel Access that enable the support of Quality-of-Service on a probabilistic basis. This paper evaluates the capabilities of the Enhanced Distributed Channel Access for supporting Quality-of-Service in distributed environments by analytic approximation and simulation.
