An Extension of the Use Case Diagram to Model Context-aware Applications
Context-aware applications have the ability to sense the context of the user and use the sensed context information to make adaptation decision in response to changes in the user’s context. Hence, besides the functional requirements, context-awareness is an important requirement of such applications. Although, the use case diagram of the Unified Modeling Language (UML) is considered as the industrial de-facto standard for modeling the functional requirements of applications, it is insufficient to accurately capture context-awareness requirements. This paper proposes an extension of the use case diagram with new notations to cater for the modeling of context-aware applications. The proposed extension called context-aware use case diagram is more expressive and enables a clear separation of concerns between context-awareness requirements and functional requirements which is helpful during requirements capture and analysis of large scale or complex context-aware applications.

An Efficient Approach for Realizing RCCAR to Resolve Context Conflicts in Context-Aware Systems Using Influential Context Elements The first step for determining the quality of context (QoC) in context aware systems (CASs) is to make sure that there are no conflicts among the values of each context element collected from different resources/sensors. ...
