A subtype of mobile ad hoc networks called vehicular ad hoc networks, or VANETs, is now one of the most comforting, motivating, and rapidly evolving (MANETs). The erratic wireless media that they transmit through includes smart cars, on-board units (OBUs), and SDN. Because of this, VANETs have different framework issues and security issues when it comes to gaining the executive's framework, all of which have an impact on the confidence in cooperation and strategy across practical frameworks. The sub-module known as the software-defined network (SDN) is part of a new VANET structure that is provided for secure communication. VANET requirements in the future are met by the scalability, programmability compliance, and global network information that the SDN offers. This study presents the scheduling protocols of the security blockchain-based architecture as well as the SDN-enabled 5G VANET model directly. Packet delivery ratio, packet loss ratio, overhead, and efficiency calculation in 5G VANET for SDN-based secured data-enabled connection are all dependent on the number of cars during the performance evaluation. Comparing the proposed SDN-based ECC system to the current efforts, like S-AODV and ES-AODV, reveals that it performs well and provides greater efficiency.
