| 摘 要： | 针对无线传感器网络平台,对基于接收信号强度(RSSI)的定位原理进行了介绍,并探究了影响RSSI的因素。利用CC2530硬件平台和TinyOS软件平台对RSSI的定位原理进行了实践性的测量工作,利用数据与图表从功率、收发点相对角度、多结点收发和环境因素等方面定量分析了RSSI影响因素的大小。同时也利用测量的数据分析得到了RSSI的Log衰减模型,并利用这一模型进行了定位实验,通过一定的算法优化,定位精度能达到1m。

| Abstract: | For wireless sensor network(WSN) platforms,the localization principle based on RSSI is introduced,and the factors that influence RSSI are explored in details.Through CC2530 hardware and TinyOS software,extensive measurements are performed.And based on the data,the factors that influence RSSI are analyzed,such as power,the relative angle between transmitter and receiver,multi transmitters and receivers,and environment.At the same time,the Log fading model of RSSI is obtained,with which a localization experiment is conducted.With some suitable algorithm,the localization accuracy can be up to 1 m. |
