Abstract

Ubiquitous Computing System (UCS) is a system where the user can get information through computer network anytime and anywhere regardless of the places. Since UCS is a personalized system, it should interact with other systems. UCS will bring a remarkable change in production, consumption, politics, economy, community, culture, and other areas related to our daily life. That is, a high-quality UCS results in high-quality services provided to users. Hence, this paper proposes a systematic quality model based on ISO/lEC 9126 in order to evaluate the ubiquitous computing system, based on ISO/lEC 9126. And, we identify key characteristics of UCS and derive the set of quality attributes based on identified characteristics. We define metrics for each quality attribute and Ubiquitous Computing Quality Model CUCQM) so that we can evaluate overall environment and important characteristics of UCS.

유비쿼터스 컴퓨팅 시스템(Ubiquitous Computing System, UCS)은 언제 어디서나 장소에 구애를 받지 않고 사용자가 컴퓨터 네트워크를 이용하여 서비스를 얻을 수 있는 시스템이다. 유비쿼터스 컴퓨팅 시스템은 개인화된 시스템으로써, 다른 시스템과 상호운영이 되는 시스템이다. 이러한 유비쿼터스 컴퓨팅 시스템은 우리 생활에 생산과 소비, 정치, 경제, 사회, 문화, 전 분야에 걸쳐 많은 변화를 가져올 것이다. 따라서 본 논문에서는 이러한 유비쿼터스 컴퓨팅 시스템을 평가하기 위하여 ISO/IEC 9126을 기반으로 체계적인 품질모델을 제안한다. 그러므로, 유비쿼터스 컴퓨팅 시스템의 품질이 좋아야 사용자에게 제공하는 서비스가 좋기 때문이다. 또한 본 논문에서는 유비쿼터스 컴퓨팅 시스템의 중요한 특징들을 식별하고, 식별된 특정을 기반으로 하여 품질속성(Quality Attribute)을 도출한다. 이렇게 도출된 품질속성을 기반으로 하여 메트릭을 정의하고, 유비쿼터스 컴퓨팅 품질모델(Ubiquitous Computing Quality Model, UCQM)을 모델링 하여 유비쿼터스 컴퓨팅 시스템의 전반적인 환경과 중요한 특정을 평가한다.
