RFID Middleware-Based Sensor Data Stream Processing System and Method

Disclosed herein is a Radio Frequency Identification (RFID) middleware-based sensor data stream processing system and method. The RFID middleware-based sensor data stream processing system of the present invention includes one or more sensors for measuring and collecting surrounding environmental information, sensor nodes for transmitting data collected by the sensors or receiving sensor management commands, a master node for transmitting or receiving data to or from the sensor nodes and for configuring the data received from the one or more sensors into data having a specific protocol structure applied in common to the sensors, and RFID middleware for receiving the sensor data from the master node, converting the sensor data into data of an Electronic Product Code (EPC), and converting the EPC data into data of a Uniform Resource Name (URN) code. Accordingly, the present invention has the advantage of processing various types of sensor data as well as RFID tags through RFID middleware, and thus ubiquitous computing can be efficiently realized.
