Managing context information in mobile devices

An advanced software framework which simplifies the development of context-aware mobile applications by managing raw context information gained from multiple sources and enables higher-level context abstractions, is discussed. This framework allows recognization of semantic contexts in real time in the presence of uncertain, noisy, and rapidly changing information and delivery of contexts for the terminal applications in an event-based manner. A blackboard-based approach was used as the underlying communication paradigm between framework entities. It is suggested that there is a need to add resource server information processing requirements.
