摘要：With the advent of pervasive computing environments, the issue related to context-aware middleware is an emerging area of research. We propose proactive services on the basis of CAMUS (Context-Aware Middleware for URC Systems). First, this paper presents the system architecture of CAMUS. CAMUS is a middleware for providing context-aware applications with development and execution methodology. Accordingly, the applications developed by CAMUS respond in a timely fashion to contexts. Secondly, this paper illustrates the contents recommendation and control service agents with the property, operation, and task for the context-aware active services. Next, proposed active services are applied to the pervasive home environment for evaluation of our system. To do this, we implement the TV contents recommendation service agent, control service agent and context-aware task using CAMUS. And we evaluate the performance of Planet communication model of CAMUS.
