ZigBee系统中基于RSSI算法的定位方法研究与实现

The Research and Implementation of Locating Method Based on RSSI Algorithm in ZigBee System

在分析无线定位技术在无线传感器网络中的应用现状以及目前常用定位算法的基础上,研究如何基于RSSI算法的主要思想并结合三边测量算法对移动节点实现定位.并基于ZigBee系统芯片CC2530组建了无线传感器网络,完成了软硬件设计与实现,最后通过实验验证了该研究的有效性和可行性.

With the rapid development of wireless location technology, its application in all walks of life become more and more widespread. Based on the study and analysis of the basic application status of wireless location technology in wireless sensor networks and the currently used localization algorithms,the position of mobile nodes was studied based on the main idea of RSSI and trilateration algorithm. A wireless sensor network was set up based on the ZigBee system chip CC2530,and hardware and software were designed and realized. Finally the effectiveness and feasibility of the study were verified through experiments.
