无线网状网路由协议的路由判据研究与改进

Research on Routing Metric of Wireless Mesh Network Routing Protocol

针对AODV协议的跳数路径判据的不足,以传统的ETX判据为基础,将链路质量、链路干扰和节点负载等参数相结合,提出新的路径判据计算方案,通过仿真实验证明,新的方案的路径选择算法有助于提高网络吞吐量,降低丢包率和平均延时,对于提高网络性能是行之有效的。

Aimed at the insufficient of hop count metric of AODV protocol, based on traditional algorithm of ETX, and combined with the parameters such as link quality, link interference and node load, a new path metric is put forward. The experimental results demonstrate that the new path selection algorithm program is helpful to improve network throughput, reduce packet loss rate and average delay, and effective for improving the network performance.
