| 摘 要： | 针对时隙ALOHA的稳定性控制问题，建立了时隙ALOHA系统模型，研究了伪贝叶斯稳定性调整算法的原理。研究了实际负荷与估计负荷的差异对调整过程的影响。结果表明，该算法能够保证系统的稳定性，其调整时间随系统总体输入负载的变化增大而变长。为减小调节时间，需要对该算法进行改进。

| Abstract: | Aiming at the stability of slotted ALOHA,this paper built the system model of slotted ALOHA,and researched the work principle of pseudo-Bayesian stability of adjustment algorithm.Researched the effect of adjusting time versus difference of compares actual terminals with estimating terminals.The result derive that pseudo-Bayesian control algorithm can assure the stability of system,but the adjusted time will become longer when the total offered load change increase.In order to reduce the time of adjusting,it... |
