DATA STRUCTURE AND MESSAGE TRANSMISSION METHOD FOR LOCATION AWARENESS ON LOCATION DETECTION SYSTEM BASED ON RFID

摘要

A message structure and a message transmission method for location awareness in a location detection system based on an RFID(Radio Frequency Identification) are provided to generate the more efficient message structure suitable for various contexts and register and store a location of a passive tag in a mobile device of a manager. A class 1 message structure(101) is applied if the number of recognized passive RFID tags is smaller than or equal to a set value. In the class 1 message structure, information about the passive RFID tag, which will be transmitted, is attached to information about active RFID tag. A class 2 message structure(102) is applied if a ratio of a value of extracting a common part to information about the whole RFID tags is smaller than or equal to a set ratio. A class 3 message structure(103) is applied if the number of recognized passive RFID tags exceeds the set ratio and the value of extracting the common value exceeds the set ratio when an algorithm for extracting the common part from goods attached with the RFID tag is applied. A class 4 message structure(104) is applied when transmitting information about sensors in order to grasp a location of the sensor.
