Scriptless Connection of Sensor Data Processing Components in Network Middleware for Home Environment
Hiroshi Noguchi, Taketoshi Mori, Tomomasa Sato · Advanced Robotics · 2008
This paper describes network middleware for distributed sensors in the home environment. The feature of the middleware is automatic connection of sensor data processing components without a fixed script. The connections of components are not directly fixed but determined based on existing components in the middleware when the components are deployed. The individual component reconnects to the target components with a condition that represents abstract sensor properties related to the target components, when the configuration of components changes. The target components are discovered with not only sensor properties but also spatial properties of sensor-attached objects such as positions and volumes. Automatic connection based on sensor properties realizes adaptability of the component to many heterogeneous sensors and sensor layouts in the home environment. Reconfiguration in the middleware was successfully shown in experiments of a monitoring application for an occupant in our experimental environment (Sensing Room).
