One of the key enablers of the evolving 5G technology are Vehicular Ad hoc Networks (VANETs) and Software Defined Networking (SDN). The development of next generation intelligent vehicular networks includes integration of SDN in Vehicular Ad hoc Networks (VANETs). Researchers have focused on the development of the integrated technology including architecture and benefits of SDN based VANET services. In this paper we have simulated the Vehicular Ad hoc Networks (VANETs) using Mininet-wifi. The VANET is incorporated with SDN controller. The performance is evaluated by varying the speed of vehicles. We have evaluated the performance in two ways: performance evaluation of V2V communication in same RSU and performance evaluation of V2V communication from different RSU. We have evaluated the proposed system for POX and RYU SDN OpenFlow controllers. As demonstrated in the results the RYU controller of SDN performs better as compared to POX controller in terms of average delay and throughput.

Technology such as vehicular ad hoc networks can be used to enhance the convenience and safety of passenger and drivers. The vehicular ad hoc networks safety applications suffer from performance degradation due to channel congestion in high-density situations. In order to improve vehicular ad hoc networks reliability, performance, and safety, wireless channel congestion should be examined. Features of vehicular networks such as high transmission frequency, fast topology change, high mobility, high disconnection make the congestion control is a challenging task. In this paper, a new congestion control approach is proposed based on the concept of hybrid power control and contention window to ensure a reliable and safe communications architecture within the internet of vehicles network. The proposed approach performance is investigated using an urban scenario. Simulation results show that the network performance has been enhanced by using the hybrid developed strategy in terms of received messages, delay time, messages loss, data collision and congestion ratio.
