Abstract:
1. A system for tracking the position of a moving object, the system comprising: WSNs (wireless sensor networks) composed of a plurality of sensor nodes, each generating connection release information representing that a connection between the corresponding WSN and a moving object having a moving node serving as a sensor node attached thereto has released if having perceived the departure of the moving object; base stations managing the plurality of WSNs and collecting position information on the plurality of sensor nodes; a node information database storing the position information on the plurality of sensor nodes collected by the plurality of base stations; middleware checking the current position information on the moving object stored in the node information database if receiving the connection release information through any of the plurality of base stations, and deleting the current position information on the moving object stored in the node information database if the checked current position of the moving object is in a WSN having perceived the departure of the moving object; and a moving-object tracking application provided with the position information on the moving object by the middleware to track the position of the moving object.
