Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...
Time aware systems claim for an explicit representation of time-related concepts, so that they can be observed and possibly controlled at run-time. The paper identifies a set of architectural abstractions capturing such concepts related to time and classifies the base activities performed by a time aware system. Our proposal has been formalized using two different modeling techniques: UML and P...
Smart Home is one of the main application domains of Pervasive Computing, and it can provide Context-aware Services to homeowners. As context information is obtained from different sources in the Smart Home environment, the context information may be heterogeneous, inaccurate and dynamic. How to effectively model these different types of context information is a main research issue. To address ...
Context-aware systems offer entirely new opportunities for application developers and for end users by gathering context information and adapting systems behavior accordingly. Several context models have been defined and various context-aware middleware has been developed in order to simplify the development of context-aware applications. Unfortunately, the development of an application by usin...
This paper proposes a new efficient approach to optimize energy consumption for energy aware buildings. Our approach relies on stochastic hybrid automata for representing energy aware systems. The model is parameterized by several cost values that need to be optimized in order to minimize energy consumption. Our approach exploits a stochastic semantic together with simulation in order to estima...
