VANETs Built on SDN: Emerging Trends in Technology and Modeling

Abstract

Integrating Software-Defined Networking (SDN) into Vehicular Ad-hoc Networks (VANETs) holds great potential to revolutionize the connectivity and functionality of current vehicular systems. This paper inspects the implementation of SDN within VANETs to improve adaptability and network administration and overcome current challenges. SDNs simplify managing changes in network configurations. Support the integration of vehicle technologies such as traffic analysis and self-driving cars by centralizing network resource management. Moreover, this article investigates the relationship between SDNs and wireless technologies such as 5G, which are essential for boosting data processing speed and minimizing delays in the data operations of upcoming transportation systems. Nevertheless, VANET's changing environment poses difficulties in scalability, security, and real-time data management. The research seeks to enhance the dependability and efficiency of SDNs in VANET settings by investigating ways to address these challenges with the objective of fostering safer transportation alternatives in the future.  The study shows enhancements in capacity efficiency and response time, as well as better resource utilization, through the simulation of SDNs in mimicking everyday traffic conditions. However, problems like scalability and security need to be overcome to fully maximize the effectiveness of SDNs in VANET.
