随着无线网络的迅速发展,网络上的业务流量与日俱增,如何保证无线网络上实时业务的服务质量问题也越来越突出。本文分析了802.11e协议的MAC接入机制,并仿真分析了在音频、视频和数据三种业务下无线网络的吞吐量和时延网络性能。仿真结果表明该协议对无线网络上的语音和多媒体应用有一定的服务质量保证。
With the rapid development of wireless networks, business traffic on the network is increasing day by day, and how to ensure the quality of service of real-time services on wireless networks is also becoming more and more prominent. This paper analyzes the MAC access mechanism of 802.11e protocol, and simulates and analyzes the performance of wireless network throughput and delay network under the three kinds of business of audio, video and data. The simulation results show that the protocol has a certain quality of service guarantee for voice and multimedia applications on wireless networks.
