非对称轮询多址门限服务排队系统高阶特性分析

Analysis on the higher order performance of unsymmetrical polling systems

从系统工作稳定的角度出发,提出一种分析方法用于非对称轮询多址服务排队系统的高阶性能研究,并以排队队长方差作为系统二阶特性参考量,采用嵌入马尔可夫链理论和概率母函数的方法,推导出排队队列方差的数学解析式,仿真实验表明理论值与仿真值有较好的一致性,在移动、多业务的情况下系统性能仍然保持稳定.

Provide a stable wireless MAC protocol to analyze the higher order performances of unsymmetrical polling systems.The method of the imbedded Markov chain theory and the probability generating function is used obtain the diversion of waiting query length.The results of computer simulation are in concordance with the theoretical analysis,and it can provide a stable delay QoS in the multi-operation mobile network.
