摘要

在无线局域网中提供QoS保证近年来日益成为研究热点.本文基于自适应无线局域网MAC协议在一种新的建模分析的基础上提出了一种提供QoS的新算法QoS-NSAD.QoS-NSAD赋予高优先级站点和低优先级站点不同的自适应特性从而很好地保证高负载环境高优先级用户的QoS特性.同时由于继承了以前算法的自适应机制

系统吞吐量能够逼近最优.大量仿真结果验证了算法的有效性.

Abstract

The provision of QoS in IEEE 802.11 Wireless LANs has recently become a research focus.Based on the previously proposed mechanism

a new self-adaptive algorithm with QoS guarantee on IEEE 802.11 wireless LAN is proposed.This new algorithm tunes the initial contention window of different priority stations dynamically to decrease the unnecessary collisions and achieves the optimal resource utilization.High priority stations and low priority stations are assigned different self-adaptive parameters to guarantee the QoS property of high priority stations.Numerous simulation results have been shown about the performance of the new mechanism.
