유비쿼터스 컴퓨팅은 언제, 어디서나, 사람과 사물의 구분 없이 상호간의 정보를 공유할 수 있는 무선 네트워크 환경을 의미한다. 유비쿼터스 컴퓨팅의 대열에서 u-센서 네트워크 기술과 함께 전파식별(Radio Frequency IDentification; RFID)기술은 다양한 산업분야에 적용가능한 차세대 핵심기술로 인식되고 있다. RFID는 사물에 초소형 칩을 부착하여 사물 및 주변 환경정보를 무선주파수로 전송하고 처리하는 일종의 비접촉식 식별기술이다. RFID 기술은 주요 산업전반에 걸쳐 다양하게 활용될 것인데 특히, RFID 시스템에서 활용하는 정보가 실시간 센서 정보로까지 발전하게 되면, 기존 애플리케이션에서 감당하던 정보량과는 비교할 수 없을 만큼 방대한 데이터가 발생하게 될 것이다. 그러나 현재 데이터처리를 담당하는 미들웨어는 주로 EPC 코드 등과 같은 간단한 형식의 데이터를 처리할 뿐, 대량의 데이터 처리에 대한 고려가 부족한 상태이다. 본 연구에서는 RFID에 대한 개념적 활용 분야와 핵심기술인 EPC global의 EPC 네트워크 구조의 구성요소를 알아보고, RFID 기반 미들웨어 동향 및 적용방안과 연속적으로 들어오는 데이터 스트림의 효과적인 실시간 처리방안을 기술하고, 주요 활용가치와 향후전망에 대해 제시하였다.

Ubiquitous Computing System is wireless networking system that exchanges information regardless of human beings and materials from everywhere. RFID technology, together with u-sensor network technology at the file of Ubiquitous Computing that can be applicable in different industrial division is recognizing as a core technology of next generation. RFID is a kind of no-touch-type identification technology where microchip is stuck in material and that transmits and manages the information of material as well as surrounding environment through the wireless frequency. RFID technology is widely utilized in industry, especially information that utilized by RFID system is generated to real time sensor, that produces massive amount of data which is incomparable to the quantity of information that was capable in past applications. However, at present data processor like middleware like EPC code, which manages only a simple type of data and there is lack of massive data management. This study investigates conceptual utilization part of RFID and core technology like EPC composition elements of network structure of EPC global, presents RFID based middleware trends and application plans, and effective real time processing plan of continuously entering data stream. And presents important utilization value and afterward prospects of RFID.
