摘要
Wireless sensor networks (WSNs) have the focus of research in recent years. Moreover, positioning is very important for wireless sensor networks. However, the positioning accuracy still has large error in the case of non-line-of-sight. In this paper, we propose an improved Kalman filter algorithm to reduce the influence of NLOS error. For the case of NLOS, the measurement residual E
