Service discovery in ubiquitous environments: Approaches and requirements for context-awareness

Abstract

We are living a democratization of ubiquitous environments offering a great number of services. Different devices, having different technical capacities access those services. Such environment requires an effective service discovery approach. In this paper, we start with a study of some existing service discovery approaches. Then we introduce a semantic and context-aware service discovery approach. We propose to distribute services registries in a P2P network. The registries will be structured according to the capacities and semantics of the services. To describe capacity and semantic of a service, we annotate its WSDL description. © 2009 Springer Berlin Heidelberg.
