Boundary Detection Using Actuated Sensor Networks

Abstract

We present an algorithm that detects and traces a contour of a scalar field. A set of static sensor nodes are deployed in a given area. The algorithm causes a mobile sensor node to approach a given contour. The algorithm uses local communication between the mobile node and its immediate neighbors only. Also, the path generated by the mobile node is near optimal when the static nodes are deployed at reasonable densities (avg. degree of about six).
