— In this paper, we study the angle coverage problem in visual sensor networks where all sensors are equipped with cameras. An object of interest moves around the network and the sensors near the object are responsible for capturing images of it. The angle coverage problem aims to identify a set of sensors that preserve all the angles of view of the object(More)
In a tracking system, an object of interest is monitored continuously in a sensor network. Information about the object is kept in the sensors and sensors transmit the information upon request. In this paper, we consider the scenario where all sensors around a targeted object capture images of it and these pictures will be sent to a mobile agent upon(More)
— In this paper, we study the angle coverage problem in visual sensor network. We consider a tracking system where an object of interest moves around the network, and the sensors surrounding it are responsible for capturing the images of it. We aim at finding the minimum cost cover which preserves all the angles of view with minimum transmission cost. We(More)
— Wireless sensor networks are under active research for tracking systems, where camera nodes are installed in a large area to take images of a targeted object. In this paper, we consider the scenario where the sensors around the object of interest capture images of it. Since some sensors are in similar viewing directions, the images they capture likely(More)
