Abstract :
Due to the growth in ubiquitous computing technology in the past few years, the need for context-aware service discovery across wide area networks is becoming prevalent. We propose GloServ, which is a global service discovery architecture that locates services throughout wide and local area networks. It supports services encompassing different domains such as events, people or places. Services can be described semantically using the resource description framework (RDF) and can be queried using the RDF query language (RQL). GloServ hierarchically defines services using RDF schemas and assigns each service a URI according to its location within the hierarchy. The hierarchical architecture for GloServ is similar to how domain names are categorized in DNS. Service discovery can either be initiated by the user or by the system. For automated service discovery, users are detected with sensors and are presented with services available according to their preferences. Graphical user interfaces for querying data is dynamically generated through the processing of RDF data.
