A Novel IoT-aware Smart Parking System based on the integration of RFID and WSN technologies

Enabling a sustainable mobility is one of primary goals of the so-called Smart Cities vision, and in this perspective, the deployment of intelligent parking systems represents a key aspect. This paper presents a novel IoT-aware Smart Parking System based on the jointly use of different technologies, such as RFID, WSN, NFC, and mobile. It is able to collect, in real time, both environmental parameters and information about the occupancy state of parking spaces. To reduce the overall system costs, the possibility to use a solar RFID tag as cars’ detection system has been analyzed. The system allows drivers to reach the nearest vacant parking spot and to pay for the parking fee, by using a customized mobile application. Furthermore, a software application based on RESTful Java and Google Cloud Messaging technologies has been installed on a CS in order to manage alert events. A proof-of-concept has been defined to demonstrate that the proposed solution is able to satisfy real requirements of an innovative Smart Parking System, while preliminary analysis of solar tag usage investigates the feasibility of the proposed detection solution.
