Wireless communication systems either ad hoc or infrastructure mode are the key challenges that must be overcome to realize the practical benefits of Quality of Service (QoS). The ability of Wireless Local Area Network (WLAN) to support real-time services is possible with QoS. To improve the QoS, the original IEEE Medium Access Control (MAC) protocol is enhanced to IEEE 802.11e standard. In this paper enhancements have been shown to effectively improve latency and throughput in 802.11e networks. A distributed adaptive algorithm allows 802.11e networks to deliver dynamic prioritization without the aid of a central coordinator. The adaptive algorithm provides QoS to high priority data.
