Abstract
After analyzing localization algorithm currently used in sensor networks,a new movement detection algorithm is introduced for active localization based on Doppler frequency shift (DFS) phenomenon. The aim of this detection algorithm is to find whether Doppler localization is out of work. The result of detection can be used as a criterion for algorithm adjustment. Simulation results shows that this hypothesis test based detection algorithm can be used to precisely find low speed moving object.
