基于PWLAN GPF的QoS性能分析与仿真

摘要

基于IEEE802.11协议中PCF/DCF技术,在无线局城网(WLAN)中,介绍了GPF的系统结构和数据帧格式等.分别对基于IEEE802.11b媒体接入控制(MAC)协议、基于IEEE802.11e媒体接入控制(MAC)协议以及基于业务划分Qos的GPF仿真的时间参数和接入原则等进行了说明.在PWLAN的3种测试环境下,时802.11b、802.11e、GPF协议的整体性能进行了仿真,并对其结果进行了分析.%The introduction of system constructure and data frames about GPF in WLAN is described,which based on IEEE802.11 standard about PCF/DCF.The time parameters and the access principle of the GPF simulation are illuminated,which base on IEEE802.11b standard about MAC,IEEE802.11e standard about MAC and Qos of partition.The result of simulation about the whole performance is analyzed,which based on IEEE802.11b,IEEE802.11b and GPF standard in three testing condition about PWLAN.
