Abstract
The new medium access protocol proposed by the IEEE 802.11 e group, namely EDCF (Enhanced Distributed Coordination Function) provides a best way to guarantee a Qos for real time and multimedia applications. However the parameters used in EDCF are static and don’t takes into account the instantaneous wireless link fluctuation, and applications requirements. In this work, we propose a new MAC access protocol AAIFS (Adaptive Arbitration InterFrame Space), which dynamically adjusts the intrinsic MAC parameters to fit both the transported stream relevant priority and wireless link overload. AAIFS protocol provides (I) a wireless link conditions aware scheme based on the measured packet loss rate (2) a differentiate QoS provisioning scheme at the mobile node side, which aggregate the different traffic into 3 service classes (3) a fair medium exploitation between the some service class belonging to different nodes.
