POSTER Adaptive OSGi-Based Context Modeling for Android

Although contextual information is recognized as a foundation of self-adapting software, context modeling middleware is often prohibitively complex and limited to small-scale deployments. To mitigate this complexity, we are developing Dynamix, a wide-area context modeling approach for Android. Dynamix simplifies context-aware application development through an extensible, OSGi-based framework that runs as a background service on a user's Android-based device, modeling context information from the environment using the device itself as a sensing, processing and communications platform. Context modeling is performed by a tailored set of plug-ins, which are dynamically provisioned to the device over-the-air during runtime. User privacy is maintained by a user-configurable context firewall. This poster introduces Dynamix's OSGI-based context modeling approach.
