Experimental validation of a wireless distributed system for smart public lighting management

This paper presents the validation of a wireless system for the smart management of the public lighting network aimed at reducing the power consumptions of the lamps. The distributed and adaptive control of the dimming profiles has been investigated taking in consideration the time-varying environmental conditions. The presented system is able to control each single lamp thanks to the integration of smart wireless devices in the existing light poles. A demonstrative deployment has been installed in different areas of the city of Trento, Italy, in cooperation with the municipality of Trento, which is responsible for the control and maintenance of the public lighting. The advantages and the limitations of the proposed solution have been experimentally assessed and the energy saving performances have been evaluated.
