Basically the system consists of a centralized microprocessor interfaced with many sensors for making the city smarter. The project aims to bring smartness in four different aspects of any city such as density based traffic monitoring, city pollution control, intensity based street light monitoring and digital water supply system. The complete system is controlled and monitored by a multipurpose web app connected to the server. The Internet of Things (IOT) shall be able to incorporate transparently and seamlessly a large number of different and heterogeneous end systems, while providing open access to selected subsets of data for the development of a plethora of digital services. Building a general architecture for the IOT is hence a very complex task, mainly because of the extremely large variety of devices, link layer technologies, and services that may be involved in such a system. In this paper we focus specifically to urban IOT systems that, while still being quite a broad category, are characterized by their specific application domain. Urban IOT, in fact, are designed to support the Smart city vision, which aims at exploiting the most advanced communication technologies to support added-value services for the administration of the city and for the citizens. This paper hence provides a comprehensive survey of the enabling technologies, protocols and architecture for an urban IOT.
