A Fair MAC Algorithm with Dynamic Priority for 802.11e WLANs

摘要：

This paper proposed a new multi-metric dynamic priority MAC algorithm for 802.1 le WLAN in order to fairly distribute the bandwidth among different kinds of traffic. Our main contribution is to dynamically adjust the priority of each queue and assign corresponding access parameters according to the value of priority function during update period. The waiting time of a packet in the queue and the ratio of actual bandwidth occupied time proportion (BP) to its promised BP share threshold are adopted as two metrics for calculating the value of priority function. The simulation result indicates that our proposed scheme could attain fairness among different kinds of traffic and decrease the ratio of packet loss, thereby improve the throughput of network.
