Context Aware Computing Systems: A survey

The term context has been studies in different areas of Computer Science. Context-aware systems have high demand in areas like Intelligent Environments, Pervasive & Ubiquitous Computing and Ambient Intelligence. Such systems gather data and adapting system behavior accordingly using context information like physical context, computational context, and user context/tasks. Developing such context-aware applications is inherently complex and hence should be supported by adequate context information modeling and reasoning techniques. In this paper the concept of context awareness is discussed along with requirements for context identification and formulation, procedure for converting context modeling to intelligent actions and context recognition techniques & algorithms are discussed. The applications of context aware are reviewed.
