战术数据链媒体接入控制协议评价方法研究

摘要

Medium Access Control(MAC) protocol has a decisive influence on the overall performance of tactical data links,and how to evaluate the performance of MAC protocol is an important part of the life cycle of tactical data links.TDMA is the most widely used access method in tactical data links, so, the evaluation indexes of slot assignment protocol were proposed,and a simulation evaluation method of slot assignment protocol for tactical data links was proposed.Then,the simulation evaluation framework was designed, the simulation models and the process of the framework were discussed. Finally, the validity of the method was verified by a simulation evaluation example.%媒体接入控制协议对战术数据链系统整体性能具有决定性的影响,如何进行媒体接入控制协议评价是战术数据链全寿命周期中需要解决的重要问题.基于时分多址在战术数据链中的广泛使用,重点设计了战术数据链时隙分配协议评价指标体系,并在此基础上,提出了战术数据链时隙分配协议仿真评价方法,给出了战术数据链时隙分配协议仿真评价框架,并对其中的仿真评价系统模型和仿真评价流程进行了阐述.最后,通过仿真示例,说明了方法的有效性.
