摘要

WLAN是当前移动互联网接入的重要方式之一，然而随着移动互联网用户数量的增加，WLAN接入性能迅速下降，提高在高密度部署条件下的性能是WLAN技术发展的重要方向。对IEEE 802.11协议中的基本媒体接入方法的分布式协调功能（DCF）进行了分析，建立模型分析基础架构WLAN 的性能，指出在基础架构WLAN中下行吞吐率在站点数量较多情况下的瓶颈及产生瓶颈的原因。采用近年来有突破性进展的全双工技术，设计新的MAC层协议并对其性能进行分析，通过对基础架构中的AP提供全双工支持以及对DCF协议进行简单修改，使基础架构无线局域网性能可以突破瓶颈，在网络负载较高的情况下保证一定的下行吞吐率，并使总吞吐量提高60%以上。

Abstract

WLAN is one of the important ways of accessing mobile internet.However，the performance of WLAN declines rapidly as the number of users increases.Improving the performance of WLAN with high density deployment is an important research direction of WLAN technology.Distributed coordination function（DCF）which was the basic media access method of IEEE 802.11 in infrastructure-based networks was modeled and the bottleneck of downlink throughput was pointed out.Taking advantage of full-duplex technology where there was a breakthrough in recent years，a new MAC protocol was designed and analyzed.By providing the AP full-duplex transmitting ability and simple modifications to traditional DCF protocol，the new protocol made the downlink throughput breaking through the bottleneck in infrastructure-based WLAN and increased the total throughput by more than 60%.
