We present a novel software architecture for context-aware applications based on a distributed, non-monolithic, simple and extensible relational model for representing context; a service-oriented architecture for computing these relations in a decoupled, flexible fashion; and with data driven, event based communication providing the kind of fine grained dynamic service composition required in mobile...
The European2228319 research project ??C-Cast?? (context-aware content casting) aims at providing an end-to-end system design for context-aware services and content provisioning. The project does not limit itself to reasoning but embraces also efficient service provisioning to user groups detected and formed according to the inferred user context. This paper presents the architecture components related...
In ubiquitous computing environments like smart home, context awareness is a very important component which aims at providing automatic services. This paper proposes chaining case based reasoning (CCBR) as the reasoning method which solves the vagueness of traditional case based reasoning (CBR) approach "In the certain case with more than one solution, we donpsilat know which solution or activity...
Context is any information used to characterize the situation of an entity. Examples of contexts include time, location, identity, and activity of a user. This paper proposes a general context-aware DBMS, named Chameleon, that will eliminate the need for having specialized database engines, e.g., spatial DBMS, temporal DBMS, and Hippocratic DBMS, since space, time, and identity can be treated as contexts...
