RESEARCH ON QUEUE LENGTH-BASED ADAPTIVE EDCA ALGORITHM IN WIRELESS MESH NETWORKS

针对无线Mesh网络的网络特性,分析无线Mesh网络中的EDCA算法,提出一种基于队列长度的自适应EDCA算法。详细讨论该算法的具体实现过程及参数变化规则,通过仿真验证了该算法在提高网络性能的同时还可以达到对不同业务流的业务区分。

In light of network property of wireless Mesh network,we analyse the enhanced distributed channel access（EDCA） algorithm in wireless Mesh network and propose a queue length-based adaptive EDCA algorithm. We discuss in detail the specific implementation process of the algorithm and the rule of parameters variation. Through simulation we verify that the algorithm can improve the networks performance,and meanwhile the business differentiation on various business flows can also be achieved.
