Abstract

This paper proposed EDWM (Extended DiffServ in the WLAN MAC) architecture, an extension of the IEEE 802.11-like MAC protocol to support various multimedia traffics. The proposed MAC consisted of three modules: Premium Service (EDWM/PS), Assured Service (EDWM /AS), and the Best-effort (EDWM/BE) functionalities. The EDWM/PS and the EDWM/AS were designed to provide the scheduling mechanism used in DiffServ routers, which were equivalent to Expedited Forwarding and Assured Forwarding, respectively, in order to guarantee QoS requirements such as low delay and bandwidth assurance. In the simulated performance, this novel approach increased the channel utilization, thus guaranteeing QoS for multimedia traffics at the same time preserving the traffic classification.
