摘　　要：针对战术通信中的网络异构性和节点群组移动性,在建立群组移动模型的基础上,采用簇头稳定分簇算法动态划分管理异构网络分层结构,提出基于链路状态的分层路由策略整合异构无线资源。该策略分为区内路由策略和区间路由策略,面向不同网络层次采用不同路由机制。OPNET仿真结果表明,该策略的分组成功接收率和平均端到端延时性能均优于分层AODV协议。Aiming at the network heterogeneity and node group mobility in tactical communication,based on building group movement model,this paper uses cluster-head stable clustering algorithm to dynamically divide and manage hierarchical structure in heterogeneous network.It presents hierarchical routing strategy based on link state to integrate heterogeneous wireless resource.The strategy consists of intra-group routing strategy and inter-group routing strategy,adopts different routing strategies for hierarchical network structure.OPNET simulation results show that this strategy has better performance of group success delivery ratio and average end-to-end delay over hierarchical AODV.
