本文对基于移动Ad Hoc网络的营连以下战术互联子网的网络环境以及应用业务类型特点进行了分析,通过OPNET仿真软件对AODV、DSR和OLSR路由协议在CBR、FTP和Voice三种不同业务类型下进行了仿真,分析了路由协议的平均端到端延时、平均吞吐量和路由控制开销。仿真结果表明,在营连以下战术互联子网在进行战场态势感知任务时,AODV和OLSR协议性能较好;而进行语音话务任务时,OLSR比其AODV和DSR协议性能好。
This paper analyzes the network environment and the application service type characteristics of the following tactical Internet subnets based on mobile Ad Hoc networks. Through the OPNET simulation software, the AODV, DSR and OLSR routing protocols are implemented in CBR, FTP and Voice three different service types Under the simulation, the average end-to-end delay, average throughput and routing control overhead of routing protocols are analyzed. The simulation results show that AODV and OLSR protocols perform well when the tactical subnets below the camp are connected to perform battlefield situational awareness tasks. OLSR performs better than its AODV and DSR protocols when performing voice traffic tasks.
