An Adaptive QoS-Supported Backoff Mechanism for IEEE 802.11

摘要：

Although the existing QoS-supported MAC Protocols can provide QoS guarantee at some degree, most of them sacrifice the performance of best-effort traffic. An Adaptive QoS-supported Backoff Mechanism for MAC Protocol is proposed, in which nodes can adjust their backoff algorithm according to the network load state they measured. So the proposed adaptive backoff algorithm can improve the link utility while at the same time meeting the QoS demand of real-time traffic. In simulation study, our algorithm shows better performance improvement over IEEE 802.11e in QoS guarantee and link utility under various scenarios.
