Abstract

A self-adaptation with context-awareness is needed within network to meet costumed services according a user's changing constraints. But the existing network has many difficulty in adding new functions because of slow standardization of network and slow deployment of new services. To solve this problem, an active network can support the suitable environment to add new function such as self- adaptation. Therefore, this Paper suggests Self Adaptation Service(SAS) using agent-based active network and the constraint-based Service Creation Environment(SCE) to support self-adaptation with context-awareness. SAS provides benefits to support the context-aware service and the fast deployment of new services.

최근 유비쿼터스 컴퓨팅 환경의 등장에 따라, 사용자의 자주 변화하는 제약조건에 맞는 서비스를 제공하기 위해서 망 내에서의 문맥인식성을 고려한 자치적응성(self-adaptation)이 요구되고 있다 그러나 기존 망에 자치적응성 기능을 추가하고자 할 때 느린 망 표준화 문제와 느린 서비스 재배치 문제가 발생한다. 액티브네트워크는 이러한 문제점을 해결하기 위한 적합한 환경으로써 망에 새로운 자치 적응성을 추가하고 빠른 재배치를 할 수 있다. 그러므로 본 논문은 문맥인식성을 고려한 자치적응성 지원을 위해서 에이전트 기반 액티브네트워크와 제약조건 기반 SCE(Service Creation Environment)클 이용한 SAS(Self Adaptation Service)를 제안하였다. 본 SAS의 이점은 망 내에서 문맥인식(context-aware)을 고려한 서비스 지원과 빠른 서비스 재배치 지원이다.
