BUTLER Final Results Available

End of the BUTLER project

The BUTLER project is officially over since October 31st. Over the three years of the project, BUTLER has laid foundations for a user oriented, context-aware Internet of Things, through key scientific breakthroughs, reusable technological components and the organisation of an open community.

The project’s final public deliverable have all been made available:

  • Deliverable 2.5 provide a complete vision of the IoT enabling technologies developed in the project: privacy and security, localization and behavior modelling, as well as a vision for potential future developments.

  • Deliverable 5.2 presents the final state of the BUTLER platform as a whole, of the project 5 field trial deployments (Shopping, Parking, Office, Health and Transport), and a quality assessment of the platform.

  • Deliverable 6.6 presents an analysis of the potential socio economic impacts of the project and of IoT as a whole, and provide clear and reusable solutions and methodologies to mitigate risks and increase acceptance and user engagement in large scale IoT deployments.

The project main reusable results are documented and made available on the IoT Open Platform Initiative web portal. Some of the project outcomes have already be made fully available as open source and others will follow.

Key Results

The BUTLER project has been a major contributor to IoT research in Europe, over the three year of the project, the partners have published in more than 85 peer reviewed conferences, 18 peer reviewed journals, and filled several patents. The project contribution to excellent research has been several times distinguished by “best papers awards” in international research conferences.

Among the major contributions of the project, BUTLER has provided an integrated architecture model for context-aware IoT applications, cutting across communication layers, integrating location, security and behaviour modelling, and addressing horizontal application domains. This architecture model is building on existing efforts such as FI-WARE and IoT-A and supported by other industry standards body, such as OMA, OAuth, SAML 2.0 or OSGi.

The components of this architecture have been developed by the project in a modular approach, some reaching already a high level of technology readiness: The BUTLER gateway provides a unifying platform that bridges the communication between the physical and virtual worlds. It provides an abstraction layer in order to access to IoT devices from various manufacturers using different protocols. The abstraction is based on a service oriented approach that allows better management of the dynamicity of the environments, easier and faster application development and other additional features such as service discovery, lookup, run-time binding and management.

The project has gone up to the deployment of some of its technologies as field trials on various domains. This includes a large scale deployment in the City of Santander of the “Smart Shopping” application: a system able to alert merchants about the optimal moments for sending notifications to citizens based on an analysis of city context information: city agenda, parking information, banking information, environmental data…

As the project evolved toward field trial and lives deployments, the project has addressed several ethical issues related with the Internet of Things. A comprehensive analysis of ethics, privacy and data protection in the IoT has been produced by the project. Together with the project guidelines for end users involvement and privacy enabling technologies they provide a complete framework for a responsible, privacy aware and user oriented IoT.

Finally, the project provided a vision of the potential socio economical impacts of the project and the IoT development, providing analysis of the obstacles to large scale deployments of the IoT and providing some reusable solutions.

Exploitation prospects

As presented above, the BUTLER project has developed many exploitable results, and each member of the consortium has clear plans to exploit the result of the project (more than 40 individual exploitable items have been identified, with clear associated plans and TRL ranging from 5 to 9).

In addition to these numerous individual opportunities, the project has developed common exploitation plans that will continue the most promising opportunities of the project and that for some of them already reach even beyond the existing consortium.
The BUTLER project has initiated the Open Platforms initiative whose objective is to provide a far reaching, open and modular set of technologies for the development of the IoT. The BUTLER project has launched the Open Platforms portal. The objective of the portal is to reference the open technologies that can be used to create Internet of Things applications but also to document their interoperability, relationships, and reference to existing use cases, infrastructures and deployments. This will enable the discovery, support and reuse of IoT component beyond the end of the projects. Newcomers to IoT application development will be able to discover existing models, libraries, tools, use cases, and deployments through complex queries including IPR, TRL, service level, and relationships with other components, effectively mapping the whole IoT Ecosystem. The open approach of a “platform of platforms” proposed here is a guarantee to address not only current foreseen IoT scenarios but also to be able to adapt to emerging needs. The BUTLER project has been joined by other EU project in this initiative, and the Open Platform Initiative has become a part of the IERC, as activity chain 1.

Among the BUTLER components that will be part of the Open Platform initiative, some assemble important sub groups of the consortium, committed to an open source approach. They form the core of an open source community that will pursue together the developments of the project. The BUTLER Gateway is among the most comprehensive, assembling at least 7 members of the consortium. Each partner involved in these common initiatives has a clear plan and agenda.

The project has also resulted in reinforced or new link between members of the consortium across the value chain of the Internet of Things, matching devices providers to integrated solution provider that reach the market. These future commercial connections have been enabled by the integration of the research results of the project and by the early deployments in the project trials. Through this process the SMEs of the consortium have been able to develop new solution that will reach the market in a short time frame after the end of the project with direct link with other consortium members.
