dc.description.abstract[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Deployment of wireless networks has risen rapidly in the last decade thanks to their convenience and flexibility. Meanwhile, multimedia service has grown to be the main part of the network traffic. As a result, Quality of service (QoS) became an indispensable part of wireless networks, and consequently 802.11e amendment has been created. There are two QoS mechanisms in 802.11e amendment, one is Enhanced Distributed Coordination Function (EDCA), and the other one is HCF Controlled Channel Access (HCCA). Since HCCA is a contention-free-based mechanism, it can provide a guaranteed QoS which is important for real time multimedia traffic. However, in IEEE802.11e amendment HCCA is not fully specified and has some overhead issues. In this thesis, we propose an innovative way to reduce overhead by utilizing beacon frame. In addition to improve the efficiency of this mechanism, we also utilize different time intervals to separate different transmission phrases and utilize certain data frame to carry traffic queue information.eng
