摘要
为了减少AODV协议链路断裂时的修复时间,提出利用Hello消息改进AODV的备份路由协议——AODV-IB,并将其应用于电力线通信(PLC)网络.AODV-IB在AODV-ABL协议的基础上,利用Hello消息携带备份路由的目的节点IP、序列号与跳数等信息,通过制定避免备份路由产生环路的规则,依据最短路径的原则,使各个节点周期交换Hello消息后均能够获得最佳的备份路由信息,即使得节点能够同时维护主路由与备份路由,并在主链路断裂时可以利用备份路由进行快速恢复.为了测试协议性能,搭建基于电力线通信网络的测试平台,对AODV-IB以及AODV、AODV-BR、AODV-ABL、IBR-AODV 5种协议进行测试.实验结果表明,电力线通信网络环境中AODV-IB在减少延时、提高数据包投递率方面较其余4种协议性能更好,更加适合在电力线通信网络中使用.
An improved backup routing protocol of AODV AODV-IB was proposed and deployed in power line communication (PLC) network in order to reduce the delay of AODV routing reconstruction. The AODV-IB modified AODV-ABL and used Hello message to carry the backup routing information of destination node IP,serial number and hops. According to the principle of the shortest path and the regula- tion of avoiding backup routing loops, each node with the AODV-IB can get optimal backup routing infor- mation after cyclical exchange of Hello message. Each node with the AODV-IB can maintain primary rou- ting and backup routing at the same time. Once the primary link breaks, it can be quickly recovered by using the backup routing. For the performance evaluation of the AODV-IB, a test-bed based on PLC net- work was constructed. Protocols of AODV-IB, AODV, AODV-BR, AODV-ABL and IBR-AODV were tested. Experimental results show that AODV-IB is vastly superior to other four protocols in the aspects of reducing the delay and improving the packet delivery ratio. AODV-IB is more suitable for the PLC net- work.
