Abstract

Since Context Driven Component model is based on the idea that a context-aware application consists of the components that are context sensitive and the components that do not depend on the context, it divides the context sensitive part into components according to which context information they are related to. The model supports the scalability of context information by building an application through composing Context Driven Components. Furthermore, it solves the embeddedness of context information inside the application logic. To show the contributions of the model, this paper applies it to Call-forwarding application, and analyses how the model supports the scalability and the embeddedness.

상황정보기반 컴포넌트 모델은 상황인식 어플리케이션이 상황정보에 민감한 부분과 그렇지 않은 부분으로 구성된다는 아이디어에서 출발하여, 상황정보에 민감한 부분을 각 상황정보의 모습과 수행 조건에 따라 분할하고 각각을 소프트웨어 컴포넌트로 구성하는 모델이다. 본 모델은 상황인식 컴포넌트들을 조합하는 방식으로 어플리케이션을 구현함으로써, 상황인식 어플리케이션의 상황정보에 따른 확장성을 지원한다. 더불어 어플리케이션 소스코드 자체에 내재되어져 있는 상황정보를 어플리케이션 로직과는 분리시킴으로써, 변화하는 상황정보에 효율적으로 적응하도록 한다. 본 모델이 갖는 특성을 보이기 위하여, 대표적인 상황인식 어플리케이션의 하나인 Call-forwarding 어플리케이션 구현에 제안한 모델을 적용하고, 이를 통해 실제 상황정보 확장에 대한 지원과 상황정보의 분리를 어떻게 해결하는지를 분석한다.
