When mobile sensors are initially deployed, some sensors may be located far away from the region of interest and due to the sensor's limited sensing of range, some sensors may not be able to participate in the coverage task. This paper proposes a new algorithm on the coverage problem for mobile sensor networks which guarantees all sensors to participate in the coverage task. The algorithm is a combination...
Underground water and waste-water pipelines are essential arteries and veins of developed cities and countries. Being hidden under the surface of the earth, these pipelines are at risk of being abandoned or damaged by “blind” construction machines digging the ground to place new utilities or undertake road or other construction works. Moreover, due to the high costs associated with the inspection...
This paper considers the deployment problem for mobile visual sensor networks equipped with omni-directional communication capability in a non-convex environment. The performance of the visual sensor is assumed to depend not only on the distance but also on the orientation from the sensor to the target. A gradient-based distributed deployment algorithms is designed to maximize the joint detection...
