A Dynamic Object Tracking Protocol for Wireless Sensor Networks

Abstract

In this paper, we propose a protocol for dynamically tracking a mobile object in a sensor network. The problem we discussed here is that one source object is set to track a mobile object, called target, in a wireless sensor network. The source is moving to approach the target. In this kind of object tracking sensor networks, the activated sensor nodes can detect an object to be tracked as well as to keep tracking of information for the source. The source follows the movement route to approach the sensor node which the object is covered in. In order to maintain the accurate route, the sensors can be worked together to dynamically adjust the route between the target and source. The source will move to reach the site of the object quickly along the adjusted route in a power saving way. Finally, we compare our scheme with others with flooding-based mechanism.
