The Wise-IoT objectives and stakeholder needs are addressed with an integrated architectural approach that builds on established IoT standards and features the following technological contributions which have been delivered :
Morphing Gateway to offer interworking between heterogeneous IoT platforms. Different sources need to be transformed in different ways. The Morphing Gateway is the technology proposed by Wise-IoT to provide a world-wide interoperable IoT infrastructure. Based on the requirements of the target platforms, domain-specific ontologies have been developed, as in the case of the bus information system, crowd modelling and smart skiing, or existing ontologies have been re-used/enhanced as in the case of smart parking. It has been described how the ontology-based information can be used in the context of oneM2M and NGSI, and how the semantic information can be used for the translation between oneM2M and NGSI in the Semantic Mediation Gateway, which will evolve into the Adaptive Semantic Module of the Morphing Mediation Gateway in release 2 of the Wise-IoT components.
Semantic interoperability components: IoT devices must be managed to be discoverable and deliver data with appropriate quality. Wise-IoT aims at automating the discovery, provisioning, and reconfiguration functions. The first version of the MMG provides the basis for building a bridge between the NGSI layer and oneM2M layer using at least two different components from two partners of the project. Using two semantic models into an unified architecture allows the upper layer application developers to access to a larger set of data and thus propose new kinds and cross environment applications for the end user. The provided release demonstrates the interest of the approach in a world in which the set of available platforms is increasing, addressing more and more environments.
Monitoring and adaptation mechanisms: in a global interoperability and mobility context, user behaviour, IoT systems capabilities, and data quality are difficult to predict. User goal fulfilment needs to be monitored and the factors affecting user trust be identified. The monitoring and adaptation mechanism is the technology proposed by Wise-IoT to win and retain users’ trust for exploitation of data offered by global IoT infrastructure. An architecture for
Trust framework and end-to-end security: the introduction of globally connected IoT systems increases the sensitivity of the data that is being collected and the scale of risk exposure when the IoT system is being attacked. The trust framework is the technology proposed by Wise-IoT to harden the security and dependability of world-wide interoperable IoT infrastructure and has been discussed within the ITU-T Y.3052 “Overview of Trust Provisioning in ICT Infrastructures and Service” working group.
Overall, the results obtained from conceptual design, implementation, and empirical evaluation of the Wise-IoT contributions are being used to evolve the worldwide standardisation landscape. As example, the project has made participation and exhibition to two interoperability events. Additionally, the project has contributed a lot to standardisation activities.
In respect to exploitation activities, the joint EU-KR collaboration has already achieved three patents and a number of joint collaboration among project partners. Also, the Wise-IoT project is performing in-line and very well to the four main exploitation axes (i.e. research market, products markets, services and technology consulting market, and standardisation sector).
