    Context-aware service coordination for mobile e-Health applications
    (European Conference on eHealth 2006, 2006) Bergenti, Federico; Caceres, Cesar; Fernandez, Alberto; Fröhlich, Nadine; Helin, Heikki; Keller, Oliver; Kinnunen, Ari; Klusch, Matthias; Laamanen, Heimo; Lopes, António; Ossowski, Sascha; Schuldt, Heiko; Schumacher, Michael
    In this paper, we present a general architecture for service delivery and coordination in intelligent peer-to-peer (IP2P) environments that has been developed within the CASCOM research project. Our essential approach is an innovative combination of agent technology, Semantic Web Services, peer-to-peer, context-awareness, and mobile computing for intelligent peer-to-peer mobile service environments. Services are provided by software agents exploiting the coordination infrastructure to efficiently operate in highly dynamic environments. Our infrastructure includes efficient communication means, support for contextaware adaptation techniques, as well as dynamic service discovery and composition planning. For end users, the architecture provides seamless access to Semantic Web Services anytime, anywhere, and using any device. Our architecture is being evaluated using a sample ad-hoc emergency healthcare assistance application scenario. We deployed a prototype of an open IP2P service environment and expect results on methods for service provision, discovery, composition, and monitoring in mobile environments.

    Efficient networking for pervasive eHealth applications
    (European Conference on eHealth 2006, 2006) Helin, Heikki; Pelt, Tim van; Schumacher, Michael; Syreeni, Ahti
    This paper presents the networking architecture developed in the CASCOM research project. This architecture provides an efficient and reliable communication support and service discovery for pervasive intelligent P2P business applications. We give an overview how wireless environments and resource-poor devices are taken into account in our architecture. For that, we have designed and implemented a new agent platform for resource-poor devices, which is a modified version of JADE/LEAP. Agents are used to coordinate (semantic) web services in the health care domain. To support the discovery of such web services descriptions, we shortly describe a distributed directory system called WSDir. It is based on federation of repositories of web service descriptions that are managed with pre-defined policies. Our architecture is being evaluated using a sample ad-hoc emergency health care assistance application scenario.
