The problem of mobile localization for wireless sensor network has attracted considerable attention in recent years.The localization accuracy will drastically grade in non-line of sight (NLOS) conditions.In this paper,we propose a mobile localization strategy based on Kalman filter.The key technologies for the proposed method are the NLOS identification and mitigation.The proposed method does not need the prior knowledge of the NLOS error and it is independent of the physical measurement ways.Simulation results show that the proposed method owns the higher localization accuracy when compared with other methods.
