An agent-based context-aware middleware for pervasive computing

Pervasive computing technology plays a key role for providing context information and offering context-aware services, which allows users to obtain digitized contents and services from wired and wireless networks virtually anywhere at any time via different handheld mobile devices. In this paper, we propose an agent-based context-aware middleware for pervasive computing environment, which is implemented in JADE agent platform and we integrated ontology and rule-based reasoning to automatically infer high-level contexts and deduce a goal of context-aware services. The middleware has been implemented as a distributed multi-agent system, which allows mobile agent delegating user's intent, roaming about the networks, searching proper resources, and supplying appropriate services for users. A Healthcare scenario demonstrates the detail functions of each agent and shows how these agents incorporate with each others.
