Abstract
WSN technology is a technology that relies on the random deployment of several sensor nodes in a certain range to obtain information. WSN technology has been fully applied in many neighborhoods, and indoor positioning technology is one of the important branches. But because the signal may be seriously disturbed by the barrier in the process of propagation, we must take some measures to improve the positioning accuracy. A robust localization algorithm based on UWB technology is proposed in this paper, which can achieve long time stable tracking with high precision. The results of real experiment and computer simulation show the effectiveness of this method.
