Luminaire-aware dynamic illuminationrole assignment scheme fora safe and greensmart city

Abstract

Devices are becoming smarter with the incorporation of sophisticated sensors, micro controllers and communication devices. A smart city integrates its core services using smart devices. The outdoor lighting application is one of the key core services, as it is a high power demand application. With the advent of sophisticated, smart luminaries, the need for an energy efficient, green smart city and adequately well-lit safe smart city has been much awaited. A safe green smart city is achieved by meticulously assigning illumination roles to every individual luminaries via a dynamic role assignment scheme. The proposed dynamic scheme assigns the illuminating task to the luminaries based on the evaluation criteria such as luminaire life span, illumination level, temperature, peak hours and critical zones. The objectives of the work is to achieve a green smart city by reducing power consumption and provide a safer smart city with adequate illumination. The proposed dynamic role assignment has been compared with the conventional lighting methods and static role assignment algorithm (COIRAS). The analyses reveal the proposed dynamic role assignment scheme achieve the objectives for a safe and green smart city.
