覆盖可靠度是度量战术互联网"动中通"能力的重要指标。首先,针对战术互联网移动节点的协同行为与想定任务、编制等密切相关的特点,归纳分析战术互联网的移动特性并总结了5种典型的战术移动模式;其次,分析战术互联网覆盖可靠度参数的内涵,建立了考虑战术移动模式影响的覆盖可靠度计算模型及仿真算法;最后,设计了仿真实验,分析了5种典型战术移动模式对覆盖可靠度的影响,从而证明了所提模型及算法的有效性。
The coverage reliability is used to measure the capability of communicating during the moving of tactical Internet.First,both typical mobility characteristics and five kinds of tactical mobility patterns are proposed,which are based on the relationship between the cooperation of nodes and tactical tasks.Second,by studying the concept of coverage reliability of tactical Internet,the coverage reliability evaluation model and an improved Monte Carlo algorithm are presented on a basis of considering the tactical mobility patterns.Finally,simulations are executed to evaluate the different influences of mobility patterns to coverage reliability of tactical Internet.The results show that the proposed model and algorithm are effective.
