基于超级节点的AODV路由协议改进

Improvement of AODV Routing Protocol Based on Super Node

在移动Ad Hoc网络中,针对AODV路由协议在路由建立过程中通过广播发现路由的缺点,本文提出一种基于超级节点的分簇思想的AODV路由改进协议。新的协议在网络中设置若干个超级节点,根据超级节点的位置将整个网络分成若干簇区,每个超级节点维护本簇区内完整的路由信息。仿真实验表明,通过该方法可以避免采用广播的方式,缩短路由建立的时间,提高数据包发送的成功率。

In mobile Ad Hoc networks,aiming at the disadvantage of the AODV routing protocol,which establishes the route with broadcast,this paper proposes a cluster to improve AODV routing protocol based on super node.In the new protocol some super nodes are set in the network,then the whole network is divided into a number of cluster regions according to the position of super nodes,each super node maintains the integrity of routing information in the own cluster region.Simulation results show that the method can be avoided by using the broadcast,shorten the route setup time,and improve the success rate of packet.
