摘要: 提出了一种新的无线传感器网络定位算法,该定位算法主要用来有效处理无线传感器网络在实际应用地理环境中遇到的一些问题,使得算法更适应于实际应用环境。研究分析了在实际应用环境中,导致RSSI测距产生误差的两大因素,基于此提出了RSSI信号理论模型在线修正方法及使用三个网络节点来实现定位的方案,以减小RSSI误差对定位精度的影响。仿真实验结果表明,算法是有效可行的。

Abstract: A new localization algorithm for Wireless Sensor Networks(WSN) is proposed in this paper.The new algorithm can handle some problems of WSN.The two key factors that result in error of distance measurement by RSSI are analyzed in this paper.In order to reduce the RSSI error,the parameters are amended online with three network nodes.The simulation results show that the algorithm is effective.
