多通道多业务优先级控制随机多址系统研究

Research on Two Multiple Channels and Multiple Services ALOHA Systems with Priority Control

在两种多通道多业务优先级控制随机多址系统模型建立的基础上 ,对这两种模型的随机争用及优先级性能进行了分析 ,分别得到了两种系统的平均成功队长、各优先级吞吐量和系统吞吐量的完整数学表达式 ,通过仿真实验验证了理论分析的正确性 .

On basis of building two models of multiple services and multiple channels ALOHA systems, authors have analyzed and compared each priority's performance in the systems. Through the analysis of performance we have abtained the integral mathematic formule of mean values of successful periods, idle and colliding periods and the throughputs of two systems. Moreover, we have proved them through simulation experiments.
