Abstract: The apparatus for tracking an object and the method thereof and the method for locating a sensor are described. The subject object tracking apparatus comprises an interface receiving sensor information and object information from a sensor communicated with an object; a first storing part successively storing sensor information in chronological order; a second storing part storing a neighborhood graph displaying an object space; and a location determining part determining a location of an object using sensor information and a neighborhood graph. According to the present invention, an accessibility graph corresponding to a space is generated and a location of a sensor is determined on an accessibility graph, thereby effectively locating a sensor and tracking an object.

Abstract: A method for optimization in an RFID location recognition system is developed to use in a blueprint in which an optimum location for installing an RFID reader is determined for using a blueprint so as to improve location recognition. The method includes the steps of inputting a blueprint and dividing a location recognition unit space from the blueprint; establishing a building interior space analysis model and an interior radio propagation space analysis model and deriving a building spatial significance and a radio propagation spatial significance; analyzing correlation between a building space and a radio propagation space and deriving a correlation coefficient; and defining an objective function for determining a location of a RFID reader based on the building spatial significance, the radio propagation spatial significance, and the correlation coefficient between the building space and the radio propagation space and performing optimization.
