分层分布式Ad Hoc网络拓扑模型的研究

Simulation Model of Topology Generation in Hierarchical Distributed Ad Hoc Networks

以战术互联网络应用环境为背景,对分层分布式Ad Hoc网络拓扑仿真模型进行了研究,提出了“分层分阶段拓扑生成算法”,拓扑仿真结果与实际网络拓扑特点相吻合。利用仿真平台GlomoSim,将不同网络拓扑连接情况的组网性能参数相比较,发现分层分布式Ad Hoc网络拓扑对系统组网效率影响较大。

Topology generation model is a very important factor in Hierarchical Distributed ad hoc network simulation architecture. Due to the hierarchical network organization and group mobility, ad hoc network performance varied with the changes in network environment. We analyzed the deployment of the radio set in US army 21st century troops, and set up a simulation model of topology generation. Different topology patterns with same characteristics are generated, and there are significant difference in network performance between random deployed network and hierarchical distributed network. Simulation results show that, simulation model of topology generation is very suitable for hierarchical distributed ad hoc networks, and has same characteristics with real deployment of the 21st century troops.
