컨텍스크 기반 미들웨어는 응용 도메인에서 실제 상황을 구현할 수 있다. 전형적으로 실제 위치를 환경에 메핑시킴으로서 실제상황을 가변적으로 변화시킬 수 있다. 또한 실제 위치에 센서와 actuator 를 이용한 서비스의 라이프사이클을 원격지에서도 가변적으로 변경할 수 있다. 이 시스템은 CAMUS[1] 시스템에서 라이프 사이클 관리를 OSGi 기반으로 한 내용을 구현하였다. OSGi 는 홈 네트워크 관련 개방형 시스템 게이트웨이 시스템으로서 OSGi 를 이용함으로써 다양한 유비쿼터스 통신, 가정, 컴퓨터 시스템간의 쉽게 라이프 사이클 관리를 할 수 있는 장점이 있다.
