| 摘 要： | 本文提出了一种新的多级门限服务轮询系统MAC控制协议的分析模型.采用嵌入马尔可夫链理论，对离散时间的多级门限服务轮询系统进行了分析，获得了轮询时刻系统队长的概率母函数，精确解析了系统的平均排队队长、平均循环周期、信息分组的平均等待时延.通过对多级门限服务轮询系统的控制机理研究，分析获得了m控制参数的有效控制取值大小和系统的相关特性.多级门限服务轮询系统综合了基本门限服务轮询系统和完全服务轮询系统，在轮询系统的MAC控制协议的应用方面更为有效.

| Abstract: | This paper proposed a novel analytical model of the polling MAC protocol using M-gated services in discrete time.By the imbedded Markov chain theory,the generating functions of queue length at server arrival epoch is obtained.Then computational equations are explicitly determined for the mean queue length,the mean polling period time and the mean packet delay.Through analysis of the mechanism of the polling model,its control values of the M-gated service and the related properties have been obtained.Meanwhi... |
