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。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 must improve the algorithm.
