摘　　要：基于随机理论提出了一种能够适应JTIDS的节点数动态变化的随机接入算法.基于随机理论,分析和比较了竞争接入算法和随机接入算法的抗毁性能,并进行了理论验证;基于OPNET建立了竞争接入算法和随机接入算法的仿真模型,通过仿真验证理论分析的合理性.对随机接入算法的抗毁性能进行了仿真,仿真结果表明,算法能够在不增加额外控制信息的情况下,动态地适应战场环境下网络拓扑结构的变化,提高了接入的可靠性,同时保证了时效性.An stochastic access algorithm, which can adapt to change of the number of nodes in JTIDS, was proposed based on stochastic theory. First, the invunerability of contention access （CA） and stochastic access （SA） were analyzed mathematically and simulated. Then, the network simulation model of CA and SA was built to verify the rationality of mathematical analysis above. Lastly, the invulnerability of SA was simulated, and the simulation results prove that this algorithm can adapt to network topology change in the battlefiled, and improve reliablity while assure timeliness.
