A service-oriented discovery framework for cooperating smart objects

Abstract

The chapter presents a service-oriented framework designed to support indexing, discovery and selection of network-enabled Smart objects. The framework allows the dynamical discovery of distributed Smart objects and, specifically, the services and operations they provide. To this end, a new metadata model has been defined to describe features, services, and operations of network-enabled Smart objects, and a service-oriented service, accessible through a REST interface, has been implemented for registering, searching and selecting Smart objects on the basis of application needs. The chapter describes the metadata model, the framework architecture and implementation, and the programming APIs.
