利用SNMP协议实现无线网设备定位

Realizing Location Services of Wireless Lan by SNMP

无线局域网技术日趋成熟,无线局域网环境中的定位服务已逐渐成为一个研究热点。文章基于SNMP协议提出一套利用无线局域网机站本身的网管功能实现定位服务的机制。文章的定位方法利用实时的网管事件报告立即进行定位,因此具有系统反应时间快、定位正确性高的优点。此外,由于使用者只需使用IP地址便可查询位置信息,该方法非常有利于发展以定位信息为基础的Web应用与服务。

With the development of wireless LAN, location-Based service has become the hotspot on WLAN research. This paper gives a method to realize location-Based service in WLAN by the function of network management of WLAN site. The method is characterized with quickly response and high correctness. Only depending with IP address, the method in this paper is in favor of developing Web application and Service based on locating information.
