Abstract

Vehicular Ad Hoc Networks (VANET) is network of vehicles communicating between each other and to the
deployed roadside units. They share information regarding traffic and infotainment. In the next generation
of VANET with 5G networks, software defined network (SDN) technology will place a very important role
for the network management. To optimize strategy to balance the latency requirement and the cost on
cellular networks, in which we encourage vehicles send the SDN control requests through the cellular
networks by rebating network bandwidth. Further, we model the interaction of the controller and vehicles as
a two-stage Stackel-berg game and analyze the game equilibrium. From the experiment results, the optimal
rebating strategy provides smaller latency than other control plane structures. Index Terms—SoftwareDefined Network (SDN), vehicular ad-hoc network (VANET)
