The Vehicular Ad Hoc Network (VANET) is regarded as one of the fundamental architectures of ITS since it provides valuable services. A VANET is a collection of moving or stationary vehicles connected via a wireless network. They manage intelligent traffic and provide real-time information as well as event collections. Initially, the main objective of VANET was to speed up the development and use of self-driving cars by providing reliable communication with the help of ITS. Nevertheless, it has evolved into a special kind of networking architecture that allows CAVs to communicate with each other and the road infrastructure. In VANET, CAVs are responsible for sending, receiving, and relaying information through V2X communication channels [4]. VANET delivers information and entertainment services known as infotainment, which requires ultra-reliable and low-latency communication models. VANET is adopted to improve road safety, control traffic congestion, regulate data flow, and facilitate emergency services through the reliable and timely dissemination of alerts and warnings. It also allows CAVs to check the weather and play music and videos on the way [5]. VANET inherits the features of the Mobile Ad Hoc Network (MANET) and is based on Telecommunication Control Protocol/Internet Protocol TCP/IP standards [6]. TCP/IP is a widely adopted communication standard for wired and wireless communications. For instance, the technologies used in the Internet of Things (IoT) and Internet of Vehicles (IoV) depend heavily on the underlying TCP/IP standards [7]. Multiple radio access methods, including Wireless in Vehicular Environments (WAVE), Dedicated Short Range Communications (DSRC), Long-Term Evolution Vehicle-to-Everything (LTE-V2X), and Cellular Vehicle-to-Everything (C-V2X), all operate under the TCP/IP standards [8]. However, the TCP/IP paradigm in VANET for the distribution of large amounts of data is challenging. In other words, TCP/IP-based communication cannot meet the requirements of a VANET due to the vehicles' frequent mobility and the dense environments [9]. Furthermore, security warnings and beacon messages that need timely communication necessitate a latency-free system. Moreover, quick content delivery, vehicle mobility management, a robust traffic management system, and adaptive routing render the TCP/IP infrastructure infeasible and make it complicated to meet the quality of service needs of various applications. Other obstacles include unstable communication between vehicles as a result of continuous changes in the networks as well as network instability. It is challenging to maintain dedicated pathways between source and destination vehicles in a TCP/IP-based VANET due to the mobility of vehicles [10]. On the other hand, a Named Data Network (NDN) is designed under the umbrella of Information-Centric Networking (ICN) [11]. NDN is a content-oriented architecture that has the potential to replace IP-based architecture in the near future. In the NDN, the data can be accessed according to their name/content/prefix rather than their IP address (host location) [12; 13]. The content's name is a key element in NDN-based communication in contrast to the IP address. Due to the benefits of NDN over traditional IP-based networking, new designs have been created to implement the VANET by using the NDN architecture [14]. Named Data Network (NDN)-enabled VANET is known as Vehicular NDN (VNDN), which has emerged as a viable data distribution option for connected vehicles (cars) [15]. Instead of safeguarding a communication connection, NDN encrypts data. However, it lacks defenses against Denial of Service (DoS) and Distributed-DoS (DDoS) attacks [16].
