The escalating growth of vehicles has amplified the complexity of Vehicle Ad-hoc Networks (VANETs), necessitating innovative strategies to combat communication delays and disruptions. In this study, we covered a literature review from 2009 to 2023 where we present a comprehensive exploration of solutions by integrating Software-Defined Networking (SDN), Programming Protocol-independent Packet Processors (P4), and Service Function Chaining (SFC). Our research addresses the core challenges of VANETs, emphasizing the specific problem of communication delays.
We conducted an in-depth analysis of SDNâ\euro™s application in VANETs, showcasing its potential to enhance network efficiency and adaptability. Additionally, we delve into the practical implementation of P4 architecture in traffic management and multihoming environments, elucidating its pivotal role in improving VANET performance. Simultaneously, we explore the intricacies of SFC and its support for services and policies in VANETs.
Our study reveals novel approaches to mitigate delays in VANETs, presenting valuable insights for both researchers and practitioners. By integrating SDN, P4 architecture, and SFC in a multihoming environment, our research not only advances the understanding of VANET challenges but also provides practical and implementable solutions for achieving efficient and low-latency vehicular communication networks. This work do not only contributes to the academic discourse but also holds significant promise for real-world applications, marking a pivotal step towards the future of seamless vehicular communications.
