| 摘 要： | 本文提出了一种将集中控制信道存取和随机信道存取相结合的混合式信道存取协议,用以解决以上两种信道存取共存时移动计算机通信系统的信道存取问题。本文以一个列车自动定位系统中的计算机移动通信网为例,提出了适用于此类系统的混合式信道存取协议,用排队理论分析了该协议的特性,并进行了模拟试验,证明此协议是正确可行的.

| Abstract: | In this paper,we present a hybrid channel access protocol which combines the central controlled channel access protocol with the random channel access pro- tocol,solving the problem of the channel access of such systems that both chan- nel access strategies are essential.We develop an automatic train location system to discuss the issues mentioned above.It turns out to be a queue system of M/M /1/K for each track under some assumptions.We analyze the queue model and present the hybrid channel access protocol.We analyse the performance of the hybrid protocol and make a simulation experiment in LAB.It proves that the hybrid channel access protocol is correct and efficient. |
