摘　　要：文章设计了一个面向无线网络的监测系统,系统基于Linux系统下的Libpcap函数库进行程序设计和实现,可以捕获802.11协议封装的MAC数据帧,根据WIFI联盟定义的帧结构对相应字段进行解析,并将解析结果存储于本地数据库中,通过4G通信模块将系统监测的无线网络数据传输到远端的系统客户端进行显示和分析。This paper designs a monitoring system for wireless networks. The system is designed and implemented based on Libpcap library in Linux system. It can capture MAC data frames encapsulated by 802.11 protocol, and then parse the corresponding fields according to the frame structure defined by WIFI alliance. The analysis results are stored in the local database. The data will be transmitted to the remote client for display and analysis by 4 G communication module.
