Pushing context-awareness down to the core: more flexibility for the PerLa language

Information technology is increasingly pervading our environment, making real Mark Weiser’s vision of a “disappearing technology”. The work described in this paper focuses on using context to enable pervasive system personalization, allowing context-aware sensor-data tailoring. Since sensor networks, besides data collection, are also able to produce active behaviours, the tailoring capabilities are also extended to these, thus applying context-awareness to generic system operations. Moreover, because the number of possible context can grow rapidly with the complexity of the application, the design phase is also supported by the possibility to speed-up and modularize the definition of the data and operations associated with each specific context, producing a support tool that eases the job of the designers of modern context-aware pervasive systems.
