无线局域网视频传输控制协议研究

A Study on Video Transform Controlling Protocol of Wireless LAN

采用嵌入马尔可夫链理论和概率母函数的分析方法,用完全服务规则和门限服务规则构造出两级循环查询无线局域网传输系统的分析模型,并对其系统性能进行分析,给出高优先级数据业务和低优先级数据业务的平均排队队长和平均时延解析式。将理论计算与计算机仿真结果进行比较,二者具有较好的一致性。

The study constructs two-level circulate query mathematic model, adopting embedded Markov chain theory and the generating function method, abiding by exhaustive service rule and gated service rule. The paper analyzes system performance and presents the characteristic of each level. Furthermore, this one presents the precise equation of average queue length and average packet delay for high-level PRI and low-level PRI operation. Theory results was compared with simulation results, the results indicates that there is consistency between these two.
