摘要
针对无线传感器网络中传统的RSSI定位算法定位精度低的问题。
Aiming at the problem of low positioning accuracy of the traditional RSSI positioning algorithm in wireless sensor networks,a method based on distributed node correlation coefficients is proposed.In the method,the anchor nodes in the target region are screened by using the constraint conditions,so as to select the anchor nodes with large correlation coefficients.The positioning is realized in the selected region with large correlation coefficients.The influence of the node distribution on the positioning accuracy is demonstrated theoretically,and the larger the distributed node correlation coefficient is,the better the node positioning effect is.A simulation experiment was carried out.The results verified that the algorithm can improve the positioning accuracy.
