Context awareness is one of the most fundamental issues in pervasive computing. In this paper, an ontology based context model is proposed, which defines "high-level" context ontology to provide basic concepts for sharing and managing context information. Our context model takes QoS and Security supporting into account. In addition, a context aware architecture based on semantic web service...
Classical tracking methods are often insufficient when dealing with complex scenarios. In order to solve tracking errors, innovative techniques based on the use of information about the context of the scene have been proposed. Context information ranges from precise measures computed on the pixels of the object neighborhood to high level representations of the entities and the activities of the scene...
Context awareness in Web services is gaining momentum. Since it is not a trivial task, it suffers from lack of a general solution.
