A Context-Aware System Architecture for Dealing with the Emergency by the Community Service in Apartment

摘要

to offer the adaptive services using the context of various devices and sensors. The user-centric service has been given a consider- able attention in Ubiquitous computing. To be sure, there have been studies concerned specially with user-centric services, but it remains the problems to be explored with emergency situation and policy. Therefore, our system is focused on the improvement to helping people such as the elderly, young children, and the disabled according to the intelligent system architecture and application. Our system manages the service access and policy which consists of notification, association, privilege and privacy. We propose a context-aware, agent-based system architecture which performs the intelligent, comfortable and safety services to meet the respective requirements. We also propose a context model using the F-logic and an agent-based system using the OSGi. Moreover, the evaluation of the system shows evidence that our system enhances the query response time for offering adaptive services and improves the maximum 20% performance of service response time compared with the conventional system of the basic architecture and context model.
