Treffer: Service Discovery in Peer-to-Peer Networks av

Service discovery is necessary to enable computers to interact with each other through heterogeneous wired and wireless networks in a seamless way. In this work, we show how the JXTA Peer-to-Peer networking infrastructure can be extended and integrated with current technologies for advanced service discovery and interaction: The DAML-S service ontology for service description, WSDL for interface descriptions, and SOAP for remote invocation. Our approach allows platform-independent interaction between devices represented by JXTA peers, and the ability to describe services with rich semantic information to enable advanced service discovery. The inference engine JTP (Java Theorem Prover) is used to reason about (evaluate) services. We have demonstrated our work by providing a simple
