针对无线传感器网络中基于RSSI的室内定位精度不高的问题,提出一种基于动态路径衰落常数和距离误差修正的改进RSSI算法。实验结果表明改进后的算法使定位点的误差得到了减小,有效地提高了定位的准确度。
Aiming at the problem that indoor positioning accuracy based on RSSI is not high in wireless sensor networks, an improved RSSI algorithm based on dynamic path fading constant and distance error correction is proposed. Experimental results show that the improved algorithm can reduce the error of locating point and improve the accuracy of locating effectively.
