一种基于RSSI技术的大楼定位系统的实现

在无线传感器网络中,位置信息对于无线网络的监测至关重要,该文提供了一种可实现的大楼人员定位系统方案。采用基于RSSI技术,定位精度在3m左右,具备可扩展性的特点和信息采集能力。

A Received Signal Strength Indicator Based on Floor Location System

With the development of wireless sensor network, it has been important to localize the sensor node. The location of sensor nodes contain the information of the place where occurrences are detected and where the data of sensor node come from. Now, base the localization ways could be carved up into two part, one is rang-based, another is range-free. Rang-based technol have received signal srength indicator, time of arrival, time difference of arrival, angel of arrival and so on. This location system is based on RSSI, realizes the localization of sensor node and the sense data collection.
