Acoustic target localization algorithm in wireless sensor networks

Abstract

Self-organizing and high fault tolerant characteristics of wireless sensor networks make them have great advantages in target tracking region, but untagged target localization is always a difficult problem to be solved. When the target appeared in the detection region, it must cause the nearby environment parameter change. This paper we use microphone to gather target signal. Much work has been done to improve the location accuracy with the effect of noise. In this paper UTLA target location method based on the signal transmission model has been proposed. The algorithm makes nodes calculate the target position cooperatively. Several experiments are made to verify the UTLA algorithm. The experimental results show that the target within sensor networks has better location result. © 2013 Springer Science+Business Media.
