METHOD AND SYSTEM FOR POSITION COGNITION USING UBIQUITOUS SENSOR NETWORK IN SHADOW ZONE OF MOBILE COMMUNICATION AND WIRELESS INTERNET

摘要

Provided are a method to recognize locations using a USN in a blind spot in a mobile communication and a wireless internet environment and a system thereof. According to an embodiment of the present invention, the location recognition method calculates the current location based on the tag information received from the adjacent tags and the reception intensity to accurately recognize the current location even when a device is not connected to the mobile communication or wireless internet or in a blind spot in the mobile communication and wireless internet environment where the connection is very weak.
