摘要
针对无线Mesh网络的网络特性,分析了无线Mesh网络的拥塞控制策略,对无线Mesh网络的拥塞程度进行分级,并提出了一种无线Mesh网络的拥塞控制算法——RICC算法。该算法主要通过移动节点不同的拥塞程度发送不同的拥塞通告消息,收到拥塞通告消息的移动节点动态地调整发送数据的速率以达到拥塞控制的目的,并通过仿真验证了该算法可提高无线Mesh网络性能。
Based on the network characteristics of wireless mesh networks（ WMNs）, the congestion control strat- egy of WMNs is analyzed, the grade of WMNs is classified, and a kind of congestion control algorithm for WMNs that RICC algorithm is presented. The different congestion announcements are sent out according to dif- ferent congestion grade of mobile node, so the mobile node that receives congestion announcement can dynami- cally adjust the rate of sending data to achieve congestion control. Analysis and simulation results verify that the RICC algorithm can improve the performance of the WMNs.
