摘要
移动自组网(MANET,MobileAdhocNetworks)是一种特殊的、应用前景广阔的新型移动无线网络。特有的网络特性使它在诸如灾难救助、战场、传感器网络、分布式计算等领域有着广泛的应用前景。结合在移动自组网络中应用最为广泛的分层结构——簇结构的特点,提出了一种基于簇结构的移动自组网多播波路由协议。协议通过对移动自组网进行簇划分,形成由簇头、簇间节点和簇内节点构成的分簇网络结构,并且在由簇头和簇间节点形成的虚拟骨干网基础上,对其进行回路检测和冗余剪枝算法处理,最终得到一个能满足多播要求的多播树,从而实现在移动自组网中的多播路由。通过对仿真实验结果的分析,该协议具有稳定的数据包发送率和较低的路由建立时间。
Mobile Ad hoc networks （MANET） are new kind of special mobile networks, which have good prospect of widely application in the field of disaster recovery, forward-deployed military networks, sensor network, distributed mobile computing and so on. In this paper, according to the characteristic of most used layered structure in mobile Ad hoc networks, clustering structure, and a clustering structure based multicast routing protocol for Ad hoc networks is proposed. Clustering networks structure which are composed of clus- terhead, gateway nodes and cluster member nodes is formed through partition of mobile Ad hoc networks. Virtual skeleton networks are composed of clusterhead and cluster gateway nodes in clustering networks structure. Multicast tree that meets the demand of multicast is obtained through looping test and redundant pruning algorithm to acquire the virtual skeleton networks. Simulating results show that steady packet delivery rate is achieved and routing time is also improved.
