Abstract: A system, method, and non-transitory computer readable medium that assigns an electric vehicle to a charging station is described. The system includes a software-defined networking (SDN) controller application stored in a cloud-based computing platform, a computing device stored in the cloud platform, and a fog and cloud-based charging service application stored in the computing device. The SDN controller application is linked to a plurality of fog servers and is configured to manage network communications between the fog servers and the cloud-based computing platform, between the fog and a number S of charging stations CSs, where s=1, 2, . . . , S, and between the fog and a number I of electric vehicles EVi, where I=1, 2, . . . , I. The fog and cloud-based charging service application determines an optimal charging station CSopt for each electric vehicle and transmits a route to the optimal charging station to the EVi.
