中文摘要：

为了抑制接收信号强度指示（RSSI）误差对无线传感器网络节点定位精度的影响,从消除RSSI误差的角度,提出了一种基于对RSSI距离值差分修正的加权质心定位算法。该算法计算简单,无需硬件扩展,仿真结果表明：该算法比传统算法有更好的定位性能。

英文摘要：

In order to suppress the effects of RSSI error on WSNs node positioning precision,from the point of view of eliminating RSSI error,weighted centroid localization algorithm based on distance difference correction of RSSI for WSNs.This localization algorithm doesn＇t need additional hardware expansion,easy computation.Simulation results show that this algorithm has better localization performance than classical algorithm.
