Using Software Defined Network (SDN) Controllers to Enhance Communication between Two Vehicles in Vehicular AD HOC Network (VANET)

Traditional Vehicular Ad-hoc Networks (VANETs) can efficiently be supplemented with the software-defined networking (SDN) paradigm which uses independent planes for data transmission and control. Integrating the SDN with the VANETs is a part of the development of intelligent VANETs. This integration technology has collected the attentions of researchers. In this paper, a new simulation model called the IoT-VANET is suggested with the SDN controller to enhance the communication between vehicles. This model uses the mininet-IoT simulator. For the purpose of comparison with previous work, a simulation model called the WiFi-VANET is built. It uses the mininet-WiFi software in two ways. Firstly, utilizing the Vehicle to Vehicle (V2V) communication performance evaluation based on the Road Side Units (RSU) and SDN controller. Three controllers of the Ryu (a Japanese word means flow), Python-based OpenFlow (POX) and centralized controller are exploited. Secondly, using the V2V communication performance evaluation based on the Global Positioning System (GPS). In terms of average delay and throughput, the performance evaluations of these two models show that the IoT-VANET is more efficient than the WiFi-VANET.
