摘要

本文针对IEEE 802.11无线局域网提出了一种基于分组到达率的区分服务实现方法

建立了一种基于二维马尔可夫链的分析模型

结果表明

在控制网络总的负荷的情况下

该方法可有效实现吞吐量的区分并且能够为各个业务流提供统计意义上的吞吐量保证.另外

该方法易于实现而且不需要对IEEE 802.11硬件做任何改动.仿真实验结果表明分析模型相当准确.

Abstract

A new service differentiation scheme based on packet arrival rate diversity is proposed for IEEE 802.11 WLAN.An analytical model is developed for performance evaluation.It’s shown that the new scheme can achieve effective service differentiation and statistical throughput guarantee by controlling the total offered load.The scheme requires no modifications at 802.11 MAC layer.Simulation results validate the analytical model.
