Improved QoS in WLAN Using IEEE 802.11e

In this paper, a detailed overview of the new attributes of a long term effective standard IEEE 802.11e to aid Quality of Service (QoS) with Wireless Local area Networks (WLANs) is presented. We address Medium Access Control (MAC) enhancements revealed in the present 802.11e draft standards by centering the problems with the legacy 802.11 standard. Cutting edge mechanisms for QoS assistance, specifically Enhanced Distributed Coordination Function (EDCF) and Hybrid Coordination Function (HCF), defined within the 802.11e drafts are usually evaluated. The effectiveness of new schemes is layed out via simulation outcomes.
