RESEARCH ON MATCH FACTOR-BASED ACTIVE QUEUE MANAGEMENT STRATEGY IN WIRELESS MESH NETWORKS

针对无线Mesh网络的网络特性,分析现有的队列管理策略,提出一种基于匹配因子的积极队列管理策略MFAQM。MFAQM算法通过网络的实际情况确定匹配因子MF,根据匹配因子来调整队列管理策略中丢包率和ECN标记概率,从而实现动态的积极队列管理。详细讨论MFAQM算法的实现过程和相关参数的计算方法,通过仿真分析验证了该算法对无线Mesh网络性能的提高。

In light of the network property of wireless Mesh networks （ WMNs）, we analyse existing queue management strategies and present a match factor-based active queue management strategy MFAQM. The algorithm determines the match factor MF through actual condition of networks, and adjusts packet loss rate and ECN marking probability in queue management strategy based on MF, so as to realist the dynamically active queue management. The paper thoroughly discusses the implementation process of MFAQM algorithm and the computation method for correlated parameters, by simulation we verify the improvement of the algorithm in performance of wireless Mesh networks.
