Abstract

Abstract: This paper proposes a localization algorithm based on the beacons moved by geometry.The main idea of this algorithm is to use values of signal strength between unknown nodes and beacons to define the field of the unknown nodes and calculate coordinate of the unknown nodes by geometry way.Experimental results show the error of this algorithm is low，and its calculation is simple so that suitable for all sizes of Wireless Sensor Networks（WSN）.

Key words: Wireless Sensor Network（WSN）, localization algorithm, signal strength
