摘要
为了降低无线自组网按需平面距离矢量路由(AODV)协议在维护路由时广播参数中源地址和目的地址均为本节点地址的路由应答报文(HELLO消息)时的网络开销,提出了一种基于广播中继(MPR)的AODV路由协议改进方案,对AODV的HELLO消息机制进行了改进,并在NS2中对改进协议和原AODV协议进行了对比仿真。仿真结果证明:改进的AODV协议在网络吞吐量、端到端时延和丢包率方面均优于原AODV协议。
In order to decrease the network overhead of broadcasting HELLO message during the process of route maintaining of the AODV protocol,the paper proposes the AODV-MPR protocol,an improved AODV routing protocol based on MPR(radio relay) , improves the HELLO mechanism of AODV,and simulates the improved protocol in comparison with the original AODV protocol on NS2 platform. The simulation result proves that the improved AODV is better than the original AODV protocol in network throughput,end-toend delay and packet loss rate.
