A Review of Internet of Things Platforms through the IoT-A Reference Architecture

For simplifying and speeding up the development of Internet of Things (IoT) ecosystem, there has been a proliferation of IoT Platforms, built up according to different design principles, computing paradigms, technologies, and targets. This paper proposes a review of main examples populating the wide landscape of IoT Platforms and their comparison on the basis of the IoT-A Reference Architecture. In such a way, heterogeneous IoT Platforms (both current and future) can be analyzed regardless of their low-level specifications but exclusively through the lens of those key functionalities and architectural building blocks that enable the interplay among devices, data flow, software, and stakeholders within the IoT ecosystem.
