Abstract

Based on the performance of received signal strength indicator（RSSI） and the limitation of trilateration localization algorithm

quadrilateral localization algorithm is proposed.In order to improve the location accuracy

computing centroid and weight centroid are used.The results of simulation achieved by C++ demonstrate show that the weight centroid algorithm has a better accuracy.Since the algorithm is simple and no extra spending of communication is needed during locating

it can be used in many areas.
