Context-aware Middleware Architecture for Intelligent Service in Mobile Environment

The Context-awareness has been premised for ubiquitous computing. Context-awareness is perception of context itself based on information from sensors. There are many denunciation of definition, but it is very important conception for intelligent service. Context-awareness middleware is necessary for context-based service through context-awareness and mobile property also considered for fast context transfer in ubiquitous environment. Contexts should be mediated through appropriate middleware to be acquired, transformed, transferred and stored for service use and an efficient discovery protocol has to enable services to search suitable context providers. In addition, reasoning engine is required for high-level contexts because numerous sensors for more intelligent service are used to context-awareness.
