MANET中编队网络的路由协议应用研究

移动自组织网络(mobile ad hoc network,MANET)中的编队网络是现实应用中的一个典型抽象。对编队网络进行分析,指出其网络拓扑变化具有全局性和阶段稳定性,其流量具有典型的不对称性;并对节点移动和网络流量进行建模。为编队网络设计混合式的路由协议——HSRP(hybrid source routing protocol),该协议采用基于拓扑变化感知的路由更新和类似多点中继的广播抑制;并融合了网络体系结构中的跨层设计思想。仿真结果表明,相比于DSR及ZRP协议,HSRP协议在丢包率及网络时延方面具有显著的优势,能更好地适应编队网络,满足应用的需要。

Reserch on the Application of Formation Network Routing Protocol in MANET

The formation network in MANET is a typical abstract of application in reality. By analysis of the formation network, we point out that the topology of the network changes globally with periodically stable topology, and the load is typical asymmetrical. Then the models of node mobility and network load were established. A hybrid routing protocol called HSRP(Hybrid Source Routing Protocol) for the formations network was designed. The protocol updates the route by apperceiving the change of the network topology. The protocol syncretizes the strategy of MRP(Multi Point Relay) and the idea of cross-layer in network architecture. Simulation results show that compared with the protocols of DSR(Dynamic Source Route) and ZRP(Zone Routing Protocol), HSRP performs better in fraction of losing packet and average end-to-end delay. The protocol could adapt to the formation network better, and meet the needs of the application.
