| 摘 要： | 随着无线局城网(wLAN)的流行,在无线局城网上进行实时多媒体应用受到了广泛重视。传统无线局城网没有提供QoS保证,无法胜任实时流的传输。EDCA实现了区分服务,改善了多媒体流的传输质量。本文首先简要介绍了EDCA机制,然后通过理论和模拟分析了基于EDCA无线局域网的VoIP性能,并分析了协议参数设置对VoIP性能的影响。

| Abstract: | With the popularization of WLAN(Wireless LAN),more attention has been paid to on real-time multi-media applica- tions over WLAN.Traditional WLAN had no guaranty on QoS(quality of service),so it can not be used to support real-time transfer effectively.EDCA realized the separation of services and thus improved the transfer quality of real-time streams.In this paper,we firstly introduced the EDCA mechanism,and then analyzed the performance of VoIP based on 802.le EDCA through theory and simulations.At last,we analyzed the affect of the setup of protocol parameters on the performance of VoIP. |
