Abstract

Scalar field mapping has many sensing application related to monitoring, rescue, disaster etc. In our work we proposed cooperative and active sensing mechanism of sensor deployed in field. The cooperative and active sensor is designed via the real-time feedback of the sensing performance to steer the mobile sensors to new locations in order to improve the sensing quality. The sensor sensing functions here defined is according to the active sensing framework that employed in sensor nodes. While sensing happened in near field area the movement of sensor taken place. During the movement of the mobile sensors, the measured value of each sensor node and its neighbors are fused with the corresponding confidences using distributed consensus filters. As a result Localization information about the presence of sensor in the sensing field can be determined and various path of sensor can be traced.
