Resumo: |
Pervasive applications use context provision middleware support as infrastructures to provide context information. Typically, those applications use communication publish/subscribe to eliminate the direct coupling between components and to allow the selective information dissemination based in the interests of the communicating elements. The use of composite events mechanisms together with such middlewares to aggregate individual low level events, originating from of heterogeneous sources, in high level context information relevant for the application. CES (Composite Event System) is a composite events mechanism that works simultaneously in cooperation with several context provision middlewares. With that integration, applications use CES to subscribe to composite events and CES, in turn, subscribes to the primitive events in the appropriate underlying middlewares and notifies the applications when the composed events happen. Furthermore, CES offers a language with a group of operators for the definition of composite events that also allows context information sharing |
