Energy Based Target Localization in a Wireless Ad Hoc Sensor Network
Prof. Yu Hen Hu

Abstract
Wireless ad hoc sensor network is an emerging technology for remote
monitoring. An important signal processing task to be performed by such
a sensor network is to detect and locate a moving or standing ground
vehicle target based on source (acoustic, seismic) signals emitted from the
vehicle's engine or transmission system. In this presentation, we
present preliminary work of a novel target localization method using the
acoustic signal energy measured at surrounding sensors. Using an
exponential energy decaying model of acoustic sources, we propose a
robust and efficient method to compute the target location based on a
maximum likelihood estimation framework. Some basic properties of the
proposed algorithm will be discussed, together with simulation results.
