摘要
时延是战术数据链的重要性能指标,时隙分配方案对时延有很大的影响。结合战术数据链L ink 16的通信协议,分析了数据链时延构成的各种因素,并采用概率周期分析方法,对主要构成因素进行了详细的统计分析。最后,采用目前常用的网络仿真软件OPNET对其TDMA组网方式进行了建模与仿真,仿真结果给出了战术数据链的时延与时隙分配方案和业务量的变化关系。
The message delay is an important performance index of tactical data link, and the method of time slot allocation has great effect on the time delay performance. According to the communication protocol of Link 16, components of delay of data link are analyzed. The main components are analyzed by using probability cyclical analysis method. OPNET, a commonly used network simulation software, was used for modeling and simulation of Link 16 TDMA network. Simulation results showed the relationship among message delay, the method of time slot allocation and network traffic.
