A Cost-effective Mobile Sensor Network for Target Area Detection

Abstract

An application model of a mobile sensor network is presented to explore an unknown target area. The proposed SensorGroup (SG) network can reduce the operation cost since only few mobile sensors are required to be organized into a group. The members of the sensing group always move following the center node. They will spread out to perform efficient detection when the center node crosses the boundary of the target area. In order to discover the target area, an S-shaped sensing mechanism is designed for the SG network structure. The detection performance is evaluated by detection completeness for different scenarios in a 100m*100m environment.
