Domain Independent Architecture and Behavior Modeling for Pervasive Computing Environments

Although pervasive computing and ambient intelligence are emerging disciplines, domain independent middleware for those scenarios are rare. In this paper we propose act-mobile as a domain independent middleware for pervasive computing environments that consists of a central service platform and locally integrated gateways, building the bridge between sensors and actuators and the act-mobile server. Through the use of a centralized server we are able to connect to controlled environments over the internet and use different clients like mobile applications for monitoring and controlling. One key feature in achieving the domain independence is the way we define the behavior of the whole system and abstract from technical details to easily provide domain dependent functionality. The used state chart-based behavior modeling is also introduced in this paper. We show how we first build properties and composed properties to achieve a higher abstraction of sensor data and apply that abstraction to actuators, too. Finally, the rules are defined based on state charts using composed properties and activities.
