    Agreement Computing
    (KI - Künstliche Intelligenz: Vol. 25, No. 1, 2011) Sierra, Carles; Botti, Vicent; Ossowski, Sascha
    In this paper we introduce the concept of Agreement Computing, motivate the central role that the concept of agreement plays in open software systems and discuss a number of research challenges that need to be addressed to make the agreement computing vision a reality.

    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.
