文档简介
本文针对基于EDCA 协议的无线局域网实时多媒体系统,提出一种基于用户冲突概率调控的接纳控制算法。并在实际802.11 系统参数下进行仿真,仿真结果表明该接纳控制算法可以在统计意义上保证各类业务的服务质量要求,并有效利用系统资源。关键字:无线局域网;服务质量;接纳控制。Abstract: In this paper, an admission control mechanism is proposed to statisticallyguarantee the QoS requirements of multimedia applications in WLANs. Simulation is performed with parameters of real 802.11 systems, simulation results shows the proposed admission control algorithm statistically guarantee the QoS of multimediaapplications while efficiently utilized the bandwidth resource.Key words: WLAN, QoS, admission control.
