AURORA: an Energy Efficient Public Lighting IoT System for Smart Cities

Public lighting accounts for a considerable amount of the total electricity consumption. Solutions to reduce its energy (and cost) footprint do exists, and they often translate into costly lamp replacement projects, which cannot be afforded by the majority of municipalities. To solve this situation, we propose Aurora: a low-budget, easy-to-deploy IoT control system that exploits the ubiquity of cellular networks (2- 4G) and scalable Cloud computing architectures to allow Smart Cities to save on the public lighting electrical bill. We deploy Aurora in a mid-size Italian municipality and we evaluate its performance over 4 months to quantify both the power and the economic saving achieved by our solution. We estimate the impact of a city-level Aurora installation and further extend the benefit analysis to most populated EU countries.
