Smart CAPs for Smart Its - Context Detection for Mobile Users

Context detection for mobile users plays a major role for enabling novel, human-centric interfaces. For this, we introduce a context detection scheme for disseminated, computer empowered sensors, referred to as Smart-Its [7]. Context-detection takes place without requiring any central point of control, and supports push as well as pull modes. Our solution is based on an in-network composition approach relying on so-called smart context-aware packets (sCAPs). sCAPs travel thru a sensor network governed by an enclosed retrieving plan, specifying which sensors to visit for gaining a specific piece of context information. For enhanced flexibility, the retrieving plan itself may be dynamically altered in accordance to past sensor readings.
