## 8 Future Directions  
In virtualized conditions, vehicles will require to communicate with the framework so as to give administrations, for example, traffic the executives, impact shirking, internet gaming, and so on. Thus, this will lead to explicit virtual network functions (VNFs) custom-fitted for systems (as the self-mending virtual capacities: self-association, terminal self-revelation, and portability of the executives) and virtual capacities for the intra and inter vehicle regions (e.g., the virtual OBU work). Then again, so as to screen traffic and stay away from security attacks, organized administrators need to indicate additional security capacities, such as virtual interruption recognition framework, virtual Firewalls, virtual intrusions protection framework, and the DDoS. Various occupants may have distinctive security prerequisites for the streams by considering the security works their streams shall cruise by. Consequently, one ought to think about the arrangement and requesting of these VNFs. In previous studies [80, 81], the authors designed various ways to deal with a secured VNF situation in particular to their requesting and launch in rush hour gridlock. This position of the secure capacities all through stream traffic of inhabitants ought to be dynamic so as to adapt to the portability of vehicles and various administrations that they give, and explain the security dangers with respect to the organization and usage of virtual system capacities. Mobile edge computing (MEC) [149] depends on a virtualization stage and empowers the application to execute at the edge of the system. The environment of the MEC is portrayed through low inactivity, closeness, huge data transfer capacity, and area mindfulness. MEC opens up administrations to buyers and ventures to convey their crucial application. The vehicular system could benefit through edge computing with the goal, for example, to expand vehicular cloud computing (VCC) into a dispersed versatile condition. MEC empowers information and the application to be put near vehicles. In safety applications related to the vehicles, the MEC applications can get information from the applications in the vehicles or RSUs. At that point, this type of application examines the information and spreads alarm cautioning alerts about the roads' environments to vehicles close by on the roads. Utilizing the MEC applications, information is quickly received, enabling the vehicles or drivers to respond right away. MEC can have distinctive VNFs, so as to permit secure interchanges of administrations between vehicles or vehicles to foundations. Initially, the integrated computer network (ICN) was imagined to tackle the squeezing necessities (e.g., gadget versatility, organize adaptability, access to data, and appropriated content generation) of the present Internet. Notwithstanding, because of its novel preferences that suit the different necessities of various system designs, along with the SDN [59], 5G, and VANETs [55], the utilization of the ICN worldview is imagined in models too. In this perspective, there are a few starter arrangements (i.e., the ICN empowered the SDN-based VANETs) that have been proposed by utilizing a broadly

The correspondence model of SDN-based VANETs replaces the conventional host-driven worldview to another data-driven one [58]. Due to the different advantages that the ICN gives, specialists have researched its use for tending to various VANET problems [55]. For example, [PERSON] et al. [150] proposed a V2I correspondence design that endeavors to convey an RSU foundation for content recovery in SDN-based VANETs. The authors elaborate that the utilization of SDN-based VANETs can give enhancements in VANETs concerning portability of executives, asset utilization, and quicker substance recovery.
