Smart transducer technology supports the composabil-ity, configurability, and maintainability of sensor/actu-ator networks. The configuration and management of such networks, when carried out manually, is an expensive and error-prone task. Therefore, many existing fieldbus systems provide means of " plug-and-play " that assist the user in these tasks. In(More)
– This paper presents a framework for generic modeling of distributed embedded applications. An application is decomposed into services and mapped on a set of distributed nodes, whereas each node hosts one or more services. Each service is described by four interfaces: a real-time input/output, a configuration and planning (CP), and a diagnostic and(More)
– Plug-and-play is an important mechanism for achieving component integration and improving interoperability in smart transducer systems. While recent research in smart transducer interfaces has achieved a syntactically well-defined interface to arbitrary sensors and actuators, current plug-and-play approaches are limited by the semantic gap between the(More)
— Transducers are sensors and actuators in order that a computer system can interact with the physical environment. An intelligent or smart transducer is the integration of an analog or digital sensor or actuator element, a processing unit, and a communication interface. In this paper we describe the basic design principles for smart transducers and compare(More)
— Testing and verification are important methods for gaining confidence in the reliability of a software product. Keeping this confidence up is especially difficult for software that has to follow fast changing development cycles or that is targeted at many platforms. In this paper we present a test framework for creating and executing function (black-box)(More)
