The Research of CLRM-HWMP Routing Protocol Based on Cross-Layer Design

在研究HWMP路由协议的基础上引入跨层设计方法,综合考虑数据链路层的数据帧传输成功率DFTE(Data Frame Transmission Efficiency)、网络层的可用带宽和节点跳数作为跨层路由度量值CLRM(Cross-Layer Routing Metric),提出一种综合路由判据的跨层路由协议CLRM-HWMP路由协议。该协议有效解决单一的路由量度判据在提高无线Mesh网络性能方面的局限问题。通过NS-3仿真工具对无线Mesh网络中的HWMP路由协议和提出的CLRM-HWMP跨层路由协议进行分析对比,实验结果表明:提出的CLRM-HWMP路由协议有效降低了节点间端到端时延、提高了数据包投递成功率和网络吞吐量。

Based on the research HWMP routing protocol on the introduction of cross-layer design approach,proposed an integrated cross-layer routing metric routing protocol CLRM-HWMP.Considering the success rate of the data frame transmission DFTE（Data Frame Transmission Efficiency）in data link layer,available bandwidth and the number of hops in network layer as a cross-layer routing metric（Cross-layer Routing Metric,CLRM）,this method is effective to solve a single routing metric criterion confined to raise the issue in the wireless Mesh network performance.By NS-3 simulation software for wireless Mesh network routing protocols and HWMP CLRM-HWMP proposed cross-layer routing protocol analysis and comparison of experimental results show that：the proposed CLRM-HWMP routing protocol effectively reduces the end to end delay between nodes,improves the packet delivery success rate and network throughput.
