A discovery service for smart objects over an agent-based middleware

This paper proposes a novel discovery framework for smart objects in the Internet of Things (IoT). The discovery service is a fundamental block of the IoT as it allows smart objects and their users to dynamically discover distributed smart objects and, specifically, the services and operations they provide. The proposed framework defines a new metadata model to describe features, services, and operations of network-enabled smart objects, and implements a service-oriented service, accessible through a REST interface, for registering, indexing, and searching smart objects. Thanks to its generic architecture and the use of open Web standards, the proposed discovery service can be easily integrated into any smart object middleware. In particular, we show its integration into an agent-based middleware supported by the JADE platform
