Abstract
유비쿼터스 컴퓨팅 환경을 구성하기 위한 핵심 기술로서 센서 네트워크에 대한 관심이 증가하고 있다. 대규모 설치와 협소한 자원을 이용하여 운용되기 때문에, 기존의 네트워크 기술을 그대로 적용할 수 없다. 또한 한번 설치되면 차후 유지 보수를 위한 추가적인 관리가 거의 불가능하다. 이러한 환경에서 다양한 응용을 필요한 시기에 즉각적으로 실행하기 위해, 메시지에 실행코드를 포함하여 전달하는 이동코드 지원 기술이 요구된다. 본 논문의 이동코드 지원 시스템은 메시지를 수신하여, 일부코드를 처리하고, 노드 상태를 포함하는 이동코드 메시지를 정의한다. 네트워크로 구성된 노드들 사이의 추상화된 메시지 계층을 지원하여 네트워크를 유동적으로 관리하고 프로그래머블한 기능을 제공한다. 응용 시나리오를 제시하여, 이동코드 메시지와 시스템의 타당성과 효용성을 검증하고, 향후 유비쿼터스 컴퓨팅 환경에서, 이동코드 시스템을 효과적으로 활용할 수 있는 기술적인 기준을 제안한다.
