摘要：
The localization is a key technology for wireless sensor network (WSN). The accuracy of localization is high in line of sight (LOS) propagation between the beacon node and unknown node. The NLOS propagation severely degrades the accuracy of localization. Therefore, the NLOS localization is one of the important challenges for WSN, in this paper, we firstly employ the Bays sequential test method to identify the propagation condition of beacon node. Then NLOS measurements which contain the NLOS error are corrected by subtracting the mean of NLOS errors to mitigate the impact of the NLOS propagation. Finally the simulation results show that the proposed method owns relatively higher localization accuracy in compare with other methods.
