环境监测无线传感器网络节点定位算法研究

无线传感器网络节点的定位技术是其关键技术之一，具有十分重要的地位。传感器节点采集到的数据必须结合其位置信息才有意义。结合环境监测无线传感器网络，通过对节点定位的基本原理和近几年国内外典型定位算法的分析研究，采用信号强度测距（RSSI）方法对其进行节点定位。为了提高定位精度，进一步对该方法进行了算法改进及节点坐标修正，最终实现了对目标的有效定位。通过仿真结果分析比较表明该方法平均定位误差小，是一种可行的定位算法。

ON LOCATION ALGORITHM OF WIRELESS SENSOR NETWORK NODE FOR ENVIRONMENT MONITORING

As one of the key technologies in wireless sensor network,the technology of node location is very important.The data acquired by node of sensor is significant only when it is combined with position information.In this paper,combining the wireless sensor network for environment monitoring and by the analytical study on the rationale of node location and typical location algorithm at home and abroad in recent years,the received signal strength indicator(RSSI) technique is used for locating its nodes.In order ...
