摘要:
为了使得WMN获得更好的负载均衡以防止网络拥塞,提出了一种适用于WMN的多路径路由协议。首先定义了一种综合考虑链路质量和节点负载的负载感知路由判据和可用带宽的计算方法,然后对路由更新机制进行了优化,并在路由请求阶段进行带宽预留,最后根据每条路径所分配的权值概率进行数据转发,进行节点问的负载均衡。仿真结果表明,与HWMP和AOMDV相比,改进后的路由协议有效避免了网络拥塞,增加了网络吞吐量,降低了平均端到端的延迟,提高了网络性能
Abstract:
In order to obtain load balance to avoid congestion in WMN, propose an improved multi-path routing which is suitable for WMN. Firstly,it defines an improved routing metric which takes into consideration the link quality and node load simultaneously and the method of computing available bandwidth, and then optimizes the routing update mechanisms and reserves sufficient bandwidth in the phase of route request. Finally, for load balance, it forwards data according to the assigned weight probability. Extensive experimental results demonstrate that the improved routing can avoid the congested area effectively,increase the throughput, reduce the average end-to- end delay and prompt the network performance compared with HWMP and AOMDV
