摘要
为了满足无线Mesh网络自身的负载均衡、路由容错与网络容量等要求,根据无线Mesh网络的网络特点,按照其路由协议的要求,分析了路由协议DSR的优缺点.引入跨层设计的方法,提出一种适用于WMN的基于综合准则的DSR跨层路由协议,该方法综合考虑了路径帧投递率、期望传输次数与平均端到端时延的因素.分析与仿真结果显示,该方法极大地提高了网络吞吐率,并且能够达到负载均衡的目的.
In order to satisfy the requirements of WMN such as load balancing,routing fault-tolerance,network capacity,and according to the characteristics of the wireless Mesh network and its routing protocol,the advantages and disadvantages of the DSR routing protocol were analyzed,a cross-layer design method was proposed,and a DSR cross-layer routing protocol was proposed that was suitable to WMN on the basis of integrated metric criterion.In this method the factors such as path frame delivery rate,expected transmission count,and average end-to-end delay were taken comprehensively into consideration.The analysis and simulation results showed that the proposed CDSR-IM protocol improved significantly the throughput of WMN,being able to reach the target of load balance.
