Abstract. Vehicle ad hoc networks (VANETs) enable wireless ad hoc communications for performing efficient driver assistance and car safety. However, pure VANETs may be not sufficient to address all modern challenges. The software-defined networking (SDN) concept with separate planes for data forwarding and control can effectively supplement traditional VANETs. In this paper, we propose a model for traffic light control and coordination along the route of emergency vehicles (fire, police, and ambulance), in which an unmanned aerial vehicle (UAV) acts as an SDN controller. This model can also incorporate the use of augmented reality (AR) to mitigate the risks and distortion introduced by the emergency vehicles.
