Unified Modeling Language (UML) is an effective tool to model information systems and to develop effective system specifications. Context Aware systems possess a dynamic behaviour based on parameters such as time and location which makes the task of modelling a context aware system quite complex namely the security requirements of the system. Since UML doesn't provide specific use cases to model Context...
We have reviewed the research of context awareness of recent years in this paper. First of all, we describe the definitions of context and context awareness which are made by different scholars in different fields, and propose our own definition. In addition, different classifications of context and context awareness are analyzed. We focus on context acquisition and sensing, context modeling and representation,...
Context aware system (CAS) is a large scale system which senses information and changes of surrounding environment, and adapts its response correspondingly. Recently, CAS is widely investigated and developed both in academy and industry. CAS is notoriously heterogeneous and complex. For this reason, it is especially important to achieve a complete and safe context aware system. Requirements analysis...
This paper addresses two fundamental research problems in the domain of context sensitive systems: the development of a generic context model that can be used to represent general purpose contexts in a computer interpretable way and the context model management. The context model is represented using a triple set consisting of context resources, actors and policies. The model is mapped onto real contexts...
