Abstract
The amalgamation of Vehicular Ad hoc Network (VANET) with the Internet of Things (IoT) leads to the concept of the Internet of Vehicles (IoV). IoV forms a solid backbone for Intelligent Transportation Systems (ITS), which paves the way for technologies that better explain about traffic efficiency and their management applications. IoV architecture is seen as a big player in different areas such as the automobile industry, research organizations, smart cities and intelligent transportation for various commercial and scientific applications. However, as VANET is vulnerable to various types of security attacks, the IoV structure should ensure security and efficient performance for vehicular communications. To address these issues, in this article, an authentication-based protocol (A-MAC) for smart vehicular communication is proposed along with a novel framework towards an IoV architecture model. The scheme requires hash operations and uses cryptographic concepts to transfer messages between vehicles to maintain the required security. Performance evaluation helps analyzing its strength in withstanding various types of security attacks. Simulation results demonstrate that A-MAC outshines other protocols in terms of communication cost, execution time, storage cost, and overhead.

By 2020, around 50 billion devices will be connected to the Internet for a better society using different technological systems
Vehicle users enjoy a better experience when amalgamating the Internet of Things (IoT) and Vehicular Ad hoc Network (VANET) architectures, and this emerging field is called the Internet of Vehicles (IoV) [2]
A cognitive engine relates to a physical data space and the cognition layer divides into cognition and resource cognitive engines at the control layer
Summary
By 2020, around 50 billion devices will be connected to the Internet for a better society using different technological systems. VANETs should be able to ensure privacy, security and reliability of messages while accomplishing efficient authentication, as well as resisting security attacks. To address such issues, an Authentication-based Medium Access Control (A-MAC) protocol is proposed in this article. One of the main challenges of the IoV deployment in the smart cities is integration of all its components Another challenge is to ensure reliable and real-time delivery of rapid emergency services and big scale of data collection between vehicular application and platform [5]. We discuss future scope related with the implementation of IoV in Section 6 and draw our conclusions
