- Abstract
Wireless location and location-based services are key technologies in wireless distributed applications. The unknown wireless nodes can be localized by means of ranging method, and the positioning results can be obtained with high precision in the line-of-sight (LOS) environment. In this paper, we study the NLOS error suppression method in the three dimensional positioning, and propose an algorithm to identify the NLOS-Anchor. Dispense with the environmental factors, even if all range values contain NLOS error, a set of anchor nodes with small errors can be find to involve in the unknown node localization, experiments show that positioning accuracy is higher than the LS and Rwgh algorithm.
