Estimation Method of NLOS Error in WSN

Yu Zhigen,Sheng Hua,Zhen Ningguo(Faculty of the Machine and Electron of Telecommunication,Huzhou Vocationaland Technological College,Huzhou,313000,China)  
An algorithm for estimating non-line of sight(NLOS) based on the ratio of the single-path arrival time to the received energy is presented to reduce effects on the non-line of sight error when a wireless sensor network has locating nodes.An NLOS formula based on the model of signal propagation path loss is constructed,and corrected in view of the antenna system′s directivity.The measured data show that the node location error reduces significantly within 45 cm after the nodes are modified by NLOS.The method can meet the location requirements for all kinds of wireless sensor networks.
