Abstract: The Internet of Things shall be able to incorporate transparently and seamlessly a large number of different and heterogeneous systems by giving open access to appropriate subsets of data for the development of a plethora of digital services. To build common architecture which is general for IoT is hence a very complex task, mainly because of the extremely large variety of devices and services that may be involved in such a system. In this paper, we focus specifically on urban IoT system which is being a broad category, are characterized by their specific application domain. Urban IoTs are designed for supporting the Smart City vision, which aims at exploiting the most advanced communication technologies to support value-added services for the administrative of the city and for the citizens. Furthermore, the paper is going to discuss and present the technical solutions and best-practice guidelines adopted in the Padova Smart City project, a proof-of-concept of deployment of an IoT island in the city of Padova, Italy, performed in collaboration with the city municipality.

Keywords: Automation, Smart Cities, Urban IOT Architecture.
