POSITION TRACKING SYSTEM USING A SENSOR NETWORK AND METHOD FOR TRACKING OBJECT USING THE SAME

摘要

A position tracking system using a sensor network and a method for tracking an object using the same are provided to track the position of the object by using an anchor node, a base node and an object node. According to a method for tracking the position of an object having an object node in a sensor network including an object node, a base node and more than one anchor node, a region is divided into grids and a grid ID is allocated to each grid. An object message including an object ID of the object node, a node ID of the base node and the grid ID is transmitted to one target node of the anchor node from the object node. The object message is routed to the base node from the target node along a routing path set using an anchor message including the node ID of the target node and the grid ID. The position of the object is sensed on the basis of the object message.
