针对网络仿真工具在流星突发组网协议仿真方面的不足,提出了应用OPNET的SITL模块来构建流星突发组网协议仿真平台的设计。根据系统在环原理,对包从虚拟到真实和从真实到虚拟的过程进行了分析,并针对流星突发通信信道和流星突发通信网协议的特殊性,对流星突发通信网采用OPNET软件进行建模仿真,实现了物理设备和OPNET仿真网络的互联。完成了仿真实验并收集了网络中数据包的传输时延和信息通过量,仿真结果表明,半实物仿真平台对流星突发通信网的仿真真实、可信。

In order to overcome the deficiency of meteor burst network,this paper introduced a method of SITL construct simulation platform to support the network protocol of meteor burst.Based on the theory of system-in-loop,this paper analyses the packet from virtue to reality and its reverse process,models the network of meteor burst for the particularity of its protocol and the meteor channel,achieves the interconnection of physical equipment and OPNET simulation network.Finally,OPNET simulation experiment is performed and packet transmission delay and network throughput are collected.Simulation results indicate that our modelling results of the meteor burst network on the semi-physical simulation platform are true and trusted.
