WaterCOM: An Architecture Model of Context-Oriented Middleware

Integrating physical and information space into applications increases application´s complexity and development difficulty. In Ubiquitous environment, context collection, aggregation and notification raise complex scientific problems and new challenges. In this paper we address these challenges by proposing a conceptual context-oriented middleware architecture. We first discuss the reason to use context in ubiquitous computing, and context-oriented middleware requirements. Then we present our approach by describing a service-oriented architecture model. It provides a dynamic adaptation ability, supports multiple context models and multi-domain context consumer. Finally, we discuss the benefit of our conceptual approach by describing and comparing current context middlewares.
