Background: Recently, the Internet of Things (IoT) has brought various changes in the
existing research field by including new areas such as smart transportation, smart home facilities,
smart healthcare, etc. In smart transportation systems, vehicles contain different components to access
information related to passengers, drivers, vehicle speed, and many more. This information can
be accessed by connecting vehicles with the Internet of Things leading to new fields of research
known as Internet of Vehicles. The setup of the Internet of Vehicle (IoV) consists of many sensors
to establish a connection with several other sensors belonging to different environments by exploiting
different technologies. The communication of the sensors faces a lot of challenging issues. Some
of the critical challenges are to maintain security in information exchanges among the vehicles, inequality
in sensors, quality of internet connection, and storage capacity.
Objective: To overcome the challenging issues, we have designed a new framework consisting of
seven-layered architecture, including the security layer, which provides seamless integration by
communicating with the devices present in the IoV environment. Further, a network model consisting
of four components such as Cloud, Fog, Connection, and Clients has been designed. Finally, the
protocol stack which describes the protocol used in each layer of the proposed seven-layered IoV
architecture has been shown.
Methods: In this proposed architecture, the representation and the functionalities of each layer and
types of security have been defined. Case studies of this seven-layer IoV architecture have also been
performed to illustrate the operation of each layer in real-time. The details of the network model
including all the elements inside each component have also been shown.
Results: We have discussed some of the existing communication architectures and listed a few challenges
and issues occurring in present scenarios. Considering these issues, we have developed the
seven-layered IoV architecture and the network model with four essential components known as the
cloud, fog, connection, and clients.
Conclusion: This proposed architecture provides a secure IoV environment and provides life safety.
Hence, safety and security will help to reduce the cybercrimes occurring in the network and thereby
provide good coordination and communication of the vehicles in the network.
