E-book Advancing IoT Platforms Interoperability
The IoT European Platforms Initiative (IoT-EPI) projects are address-ing the topic of Internet of Things and Platforms for Connected Smart Objects and aim to deliver an IoT extended into a web of platforms for connected devices and objects that supports smart environments, businesses, services and persons with dynamic and adaptive configu-ration capabilities. The specific areas of focus of the research activities are architectures and semantic interoperability, which reliably cover multiple use cases. The goal is to deliver dynamically-configured in-frastructure and integration platforms for connected smart objects covering multiple technologies and multiple intelligent artefacts. The IoT-EPI ecosystem has been created with the objective of increasing the impact of the IoT-related European research and innovation, in-cluding seven European promising projects on IoT platforms: AGILE, BIG IoT, INTER-IoT, VICINITY, SymbIoTe, bIoTope, and TagItSmart.This white paper provides an insight regarding interoperability in the IoT platforms and ecosystems created and used by IoT-EPI. The scope of this document covers the interoperability aspects, challeng-es and approaches that cope with interoperability in the current ex-isting IoT platforms and presents some insights regarding the future of interoperability in this context. It presents possible solutions, and a possible IoT interoperability platform architecture. Due to the critical and important role of interoperability in IoT systems, it is strongly related with many relevant topics and aspects in IoT: performance, compatibility, integration, ROI, market accep-tance, development design, architecture.The creation and development of this white paper has taken ad-vantage from outcomes and available information from other activi-ties in the framework of the IoT-EPI projects. In particular, important sources of information that complement the authors’ research are the IoT-EPI platforms reports and the exchange of information among the projects during the work in task forces.Regarding the output of this work, this white paper intends to be a useful source of information of interoperability in IoT platforms. This critical aspect in IoT systems has relevance and impact on the topics of each Task Force of the IoT-EPI (Innovation, Platform Interoperability, Community Building, Business Models, Educational Platforms, Inter-national Cooperation).The research regarding interoperability architecture is useful for the current and future IoT platforms and IoT projects, as it provides deep awareness and valuable insights regarding the critical aspect of interoperability in them, as well as possible architecture solutions to the challenges that the achievement of platform interoperability in-volves. This information can be valuable in the development of new services, applications and businesses on top of IoT platforms. Lack of platform interoperability causes major technologic and economic drawbacks such as impossibility to plug non-interoperable IoT devices into heterogeneous IoT platforms, impossibility to develop IoT applications exploiting multiple platforms, slowness of IoT tech-nology introduction at a large-scale, discouragement in adopting IoT technology, vertical silos in IoT ecosystems and markets, increase of costs, scarce reusability of technical solutions, or user dissatisfaction.
