Classification of Object Tracking Techniques in Wireless Sensor Networks
Object tracking is one of the killer applications for Wireless Sensor Networks (WSN) in which the network of wireless sensors is assigned the task of tracking a particular object. The network employs the object tracking techniques to continuously report the position of the object in terms of Cartesian coordinates to a sink node or to a central base station. A family tree of object tracking techniques has been prepared. In this paper, the authors have summarized the object tracking techniques available so far in wireless sensor networks.
