Field sensing and target tracking using mobile sensors

Abstract

We investigate the problem of gathering of sensory data from a non-convex area (without a hole) using mobile sensors when certain regions of the area are under attacks from intruders. The theory of sensing and tracking targets is based on the idea of a potential field wherein the sensors move towards the areas of intrusion due to the existence of mutually attractive forces between intruders and sensors, and move away from each other due the existence of mutually repulsive forces between themselves. A set of algorithms have been proposed on the basis of the fore-mentioned potential field theory which accomplishes the twin objectives of field sensing and target tracking efficiently. © 2009 Springer.
