With a subtle rise in the vehicular traffic, it has become necessary for the users to be more aware of their surroundings. Vehicular AdHoc Network (VANET) provides a solution to connect these vehicles with the data centers to leverage this information for the benefit of the users. It renders end-to-end details for traffic flow monitoring and dynamic route scheduling of vehicles to prevent unforeseen incidents. Current researches suggest that numerous IoV architectures authenticate the vehicles enabling inter-vehicular communication. To improve the quality of service, this work leverage vehicle-to-roadside communication, and priority based batch-verification system. Further, to ensure safer computations of time-critical information and faster processing of event-driven messages, vehicular edge computing based hierarchical framework is proposed. The security analysis proves that this framework can substantially improve power consumption and mitigate security issues such as traceability, identity privacy-preserving, replay attacks, denial of service attacks, and impersonate attacks.
