软件定义的虚拟网络调查：好处、挑战和未来方向
A Survey on Software-Defined VANETs: Benefits, Challenges, and Future Directions
摘要：
第五代（5G）网络的发展正越来越容易成为新应用和商业模式增长的主要驱动力。随着下一代智能车载网络和应用的发展，车载自组网（VANG）和软件定义网络（SDN）代表了5G技术的关键推动力。近年来，研究人员专注于SDN和VANET的集成，并研究与架构相关的不同主题，软件定义VANET服务的好处以及适应它们的新功能。然而，完整的体系结构的安全性和健壮性仍然是值得怀疑的，并已在很大程度上被淘汰。此外，部署和集成新的实体和几个架构组件驱动新的安全威胁和漏洞。在本文中，首先，我们调查了最先进的SDN为基础的车载ad-hoc网络（SDVN）架构的网络基础设施的设计，功能，优点和挑战。最后，我们讨论了SDVN体系结构对主要安全威胁的应对措施，这些安全威胁违反了关键的安全服务，如可用性、机密性、身份验证和数据完整性，我们还提出了不同的对策，最后，我们讨论了经验教训和未来的研究工作方向，为未来的SDVN体系结构提供严格的安全和隐私解决方案。据我们所知，这是第一个全面的工作，提出了这样的调查和分析SDVN在未来一代网络（例如，5G和以信息为中心的网络）和应用（例如，智能交通系统，以及温哥华的物联网广告）。
英文摘要：
The evolving of Fifth Generation (5G) networks isbecoming more readily available as a major driver of the growthof new applications and business models. Vehicular Ad hocNetworks (VANETs) and Software Defined Networking (SDN)represent the key enablers of 5G technology with the developmentof next generation intelligent vehicular networks and applica-tions. In recent years, researchers have focused on the integrationof SDN and VANET, and look at different topics related to thearchitecture, the benefits of software-defined VANET servicesand the new functionalities to adapt them. However, securityand robustness of the complete architecture is still questionableand have been largely negleted. Moreover, the deployment andintegration of novel entities and several architectural componentsdrive new security threats and vulnerabilities.In this paper, first we survey the state-of-the-art SDN basedVehicular ad-hoc Network (SDVN) architectures for their net-working infrastructure design, functionalities, benefits, and chal-lenges. Then we discuss these SDVN architectures against majorsecurity threats that violate the key security services such asavailability, confidentiality, authentication, and data integrity.We also propose different countermeasures to these threats.Finally, we discuss the lessons learned with the directions offuture research work towards provisioning stringent security andprivacy solutions in future SDVN architectures. To the best of ourknowledge, this is the first comprehensive work that presents sucha survey and analysis on SDVNs in the era of future generationnetworks (e.g., 5G, and Information centric networking) andapplications (e.g., intelligent transportation system, and IoT-enabled advertising in VANETs).
