Semantic-Based Context-Aware Service Discovery in Pervasive-Computing Environments

Service discovery is vital in pervasive-computing environments, where a great number of devices and software components collaborate unobtrusively and provide numerous services. Current service-discovery protocols do not make use of contextual information in discovering services, and as a result, fail to provide the most appropriate and relevant services for users. In addition, current protocols...

Secure and Private Service Discovery in Pervasive Computing Environments

Every year, billions of computing devices are built and seamlessly integrated into our surroundings and daily lives. In the near future, we will live in pervasive computing environments. In these environments, devices range from traditional PCs, printers, or servers, to devices that people carry, wear, and to the devices that are embedded into commodities and ambient environments. Smart phones,...

Efficient Semantic Service Discovery in Pervasive Computing Environments

Service-oriented architectures, and notably Web Services, are becoming an incontrovertible paradigm for the development of applications in pervasive computing environments, as they enable publishing and consuming heterogeneous networked software and hardware resources. Combined with Semantic Web technologies, in particular ontologies, Web services’ descriptions can be unambiguously and automati...

Towards Distributed Service Discovery in Pervasive Computing Environments

The paper proposes a novel distributed service discovery protocol for pervasive environments. The protocol is based on the concepts of peer-to-peer caching of service advertisements and group-based intelligent forwarding of service requests. It does not require a service to be registered with a registry or lookup server. Services are described using the Web Ontology Language (OWL). We exploit t...
