ABSTRACT

“Quality of Service (QoS) requirements like good throughput and minimum access delay are challenging tasks to accomplish with regard to 802.11 WLAN protocols and Medium Access Control (MAC) functions. In this article, a distributed medium access scheme called EDCF, which is adopted in an upcoming standard IEEE802.11e to allow prioritized medium access for applications with QoS requirements, is described and discussed. Its performance is also evaluated via simulations using network simulator called OPNET”
