基于K-最近邻基站的移动手机自组网路由协议胡 君 徐署华 王 雷


摘 要:通过分析AODV算法及其存在的问题,结合节点的移动速度和方向等信息, 提出了一种基于K-最近邻基站的移动手机自组网混合路由协议。在新协议中, 当网络的本地基础设施发生故障时,每个本地节点首先生成并维护一个K-最近邻基站信息表,然后基于该K-最近邻基站信息表,利用改进的AODV协议来进行按需路由。理论分析与仿真结果表明, 新算法的性能要优于传统的按需路由协议AODV,因此,更适合移动手机自组网中的路由。

  Abstract:By analysing the AODV protocol and its defect,then considerded the information about the moving speed and direction of nodes,this paper presented a new hybrid routing protocol for mobile Ad hoc cell phone network based on K-nearest neighboring base stations, in which, when the local network infrastructures fail or was destroyed,each local node would generate and maintenance a K-nearest neighboring base stations information table, and then, based on the table,used the improved AODV protocol to do on-demand routing.Theoretical analyses and simulation results show that, the newly proposed protocol has better performance than the traditional on-demand routing protocol AODV, so it is more suitable for routing in mobile Ad hoc cell phone networks. ......
