针对无线Mesh网络的特性,分析了随机早期检测(random early detection,RED)算法的实现过程,提出了一种基于链路状态的RED(link-states-based RED,LS-RED)算法。该算法的基本思想是通过移动节点的链路状态信息动态调整RED算法中的4个参数。详细讨论了LS-RED算法的实现过程,提供了无线网络下LS-RED算法参数的设置方法,并对该算法实现过程进行了分析,通过仿真分析验证了该算法对无线Mesh网络性能提高的有效性。

RED（ random early detection） algorithm is an important method to improve the performance of networks. To im- prove the capacity of wireless mesh networks, we propose an RED algorithm that is based on link states. The parameter of RED algorithm changes according to the information of link states. In addition, through a performance study and the results of simulation, we show that the proposed protocol can increase throughput and reduce delay in multiehannel wireless mesh networks.
