Discovering Web Things as Services within the Arrowhead Framework

The IoT is spreading heavily around us and many new standard at different architectural layers proliferate. This creates a heavy interoperability gap that many architectural proposals and new standards have tried to cope with over the years. In particular, we take into account the Arrowhead interoperability Framework, a powerful and promising paradigm for interconnecting local clouds and we demonstrate the possibility to integrate it with the emerging W3C Web of Things standard. We study the usage of the Arrowhead Framework as a potential candidate for discovery operation and inclusion of WoT ecosystems within Service Oriented Architectures (SOA), in order to support the integration of legacy and proprietary systems. To this aim, a three-layered architecture is proposed and validated experimentally on a proof-of-concept use case, by highlighting the advantages of the proposed integration.
