提出了一种连续与离散时间混合控制的多通道随机多址接入协议(MRMCS),设计了离散时间接人和连续时间接人相结合的控制时钟,采用概率P的选择、负载均衡技术,对多通道优先级业务控制的随机多址系统进行了研究.由于综合了时隙式接入控制和连续时间型接入控制的优点,使得连续与离散时间混合控制的多通道随机多址系统的性能得到了提高.通过建模分析,得到了CSMCMA网络协议的吞吐量解析结果.仿真实验结果表明理论分析和仿真实验相一致.同时,仿真实验还给出了概率检测时隙式和概率检测连续型随机多址系统的比较结果,说明双时钟控制系统的较优性能.
A multi - channel and random multiple - access protocol ( MRMCS ) with consecutive time and slotted time are presented. The control clock was designed by consecutive time and slotted time together. The choice of the probability and the channel load equilibrium were adapted to study the random system with multichannel and multi -service controlling. Due to the advantages of slot time combining with consecutive time, the performance of multi - channel and multi - service random multi - access protocol with consecutive time and slotted time was improved. Furthermore, it analyzed the systemic throughput of MRMCS protocol. The results show that the simulation is in concordance with the theoretical analysis. In other words, the comparing results with slotted- time and continuous- time CSMA system show the MRMCS protocol is better.
