Abstract

기존 미들웨어는 클라이언트와 서버 사이에서 필요로 하는 서비스를 효율적으로 제공하는 소프트웨어이지만, 상황인식 기능 부재로 일관성이 미흡하고, 다양한 의미관리나 보안체계등의 문제로 인해 RFID 시스템에 적용할 수 없으며 기존 연구도 미흡하다. 따라서 새로운 기준의 RFID 미들웨어 선정을 위한 품질 선정 프로세스와 품질평가 방법이 필요하다. 본 논문은 국제표준 ISO/IEC 14598을 바탕으로 새로운 선정 프로세스를 제안하고, 제안된 프로세스를 통해 최적의 품질요소를 추출, 선정하였다. 선정된 품질요소는 표준 품질모델인 ISO/IEC 9126의 품질 특성과 SUN, Microsoft, EPCglobal, IBM등 RFID 미들웨어 품질요소들과의 매핑하였다. 이러한 과정을 통해 제안된 프로세스에 의해 추출, 선정 품질요소가 공정하고 적절한 RFID 미들웨어 품질요소로 추출, 선정하였음을 보여주었다. Conventional middleware is software providing services between clients and servers efficiently, but it is not applicable to RFID systems because of low consistency due to the absence of context awareness function, and problems in the management of meaning, security system, etc. Accordingly, we need a quality selection process and a quality evaluation method for selecting RFID middleware based on new criteria. This Paper proposed a new selection process based on international standard ISO/IEC 14598, and extracted and selected optimal quality factors through the proposed process. The selected quality factors were mapped to the quality characteristics of standard quality model ISO/IEC 9126, and to quality factors of RFID middleware of SUN, Microsoft, EPCglobal, IBM, etc. The results of these works showed that the quality factors extracted and selected through the proposed process were fair and adequate for evaluating the quality of RFID middleware.
