移动Ad hoc网络分簇拓扑结构及性能分析

Clustering topology and Performance Analysis in Mobile Ad hoc Network

针对移动Ad hoc网络分层拓扑结构存在的"瓶颈"隐患、"稳健性"差,以及因成员节点切换而引起的簇域构造频繁等问题,本文提出了一种改进的拓扑结构并进行了性能分析。它通过连通统治集内各簇头,使簇头之间可以相互直接通信,从而消除网关成为自治系统的"瓶颈"隐患,解决因"乒乓切换"所引发的簇域频繁构造问题,增强自治系统的"稳健性"。此外,改进的拓扑结构在没有增加任何新的物理设备的情况下,还能在一定程度上减少簇域之间的通信时延,提高网络安全性。

A new kind of topology is put forward and performance is analyzed to solve the problems of bottle-neck,bad robustness and clustering area construction frequency caused by member nodes’ handoff in exiting hierarchy mobile Ad hoc network. Cluster headers in our proposed topology connect to each other to communicate directly,which can remove the problem of gateway’s bottle-neck and solve clustering construction frequency resulting from ping-pong handoff as well as improve robustness of autonomous sys-tem.
