In sensor network processing environments, the current location tracking method has problems in accuracy on receiving the transmitted data and pin-pointing the exact locations depending on the applied methods, and also has limitations on decision making and monitoring the situations because of the lack of consideration on context-awareness. In order to overcome such limitations, we propose a method which utilizes context-awareness in a data processing module which tracks a location of the magnetic object (Magnetic Line Tracer) and controlled introspection data based on magnetic sensor. Also, in order to prove its effectiveness we have built a wireless sensor network test-bed and conducted various location tracking experiments of line tracer using the data and resulted in processing of context-aware data. Using the updated data from the previous study, we have analyzed the effectiveness of the proposed method for locating the information database entries and for controlling the route of line tracer depending on context-awareness.
