战术数据链层次化网络拓扑模型研究

Simulation Model of Hierarchical Topology Generation in Tactical Data Link

以战术数据链应用环境为背景,对战术数据链层次化网络拓扑模型进行了研究,提出了"分层聚类拓扑生成算法",拓扑仿真结果与实际网络拓扑特点相吻合。利用仿真平台NS2,将不同网络拓扑连接情况的组网性能参数相比较,发现层次化网络拓扑对系统组网效率影响较大。

Topology generation model is a very important factor in tactical data llnk network simulation architecture. Due to the hierarchical network organization and group mobility, tactical data link network performance varied with the changes in network environment. We set up a simulation model of topology generation, which has same chacteristics with real deployment of the troops. Different topology patterns with same characteristics are generated, and there are significant difference in network performance between random deployed network and hierarchical network. Simulation results show that, simulation model of topology generation is very suitable for hierarchical distributed tactical data link networks.
