I NTERNET of Vehicles (IoV) is a large interactive network composed of information such as vehicle location, speed and route. Vehicles can collect their own environment and state information through GPS, RFID, sensors, camera image processing, and other devices. They can transmit their various information to the central processing unit through Internet technology. These large amounts of vehicle information can be analyzed and processed through computer technology to calculate the optimal route

... or different vehicles, and report road conditions in time and schedule signal light cycles. Internet of Vehicles (IoV) is a large-scale system network for wireless communication and information exchange between vehicles and people, vehicles and roads, vehicles and the Internet, which is based on intra-vehicle network, inter-vehicle network and vehicle mobile Internet, in accordance with the agreed communication protocols and data interaction standards. The system realizes the integrated network of intelligent traffic management, intelligent dynamic information service, and intelligent vehicle control by "filtering and cleaning" massive data and processing data on the platform. Internet of Vehicles (IoV) system utilizes advanced IoT technology, cloud computing, and big data to make the system fully aware of roads and traffic. It enables all vehicles to collect information through their own environment and state, and upload all kinds of information to the Internet big data platform. The central processing unit collects, analyzes, and processes a large amount of uploaded information. The system will control every vehicle involved in the traffic and control every road in real time to provide users with traffic efficiency and safety. SDN can provide a feasible, cost-effective way to manage IoV and ensure network security. What's more, it can furthest improve the application programs and analyze performance. Due to the explosive growth of IoV and the chaotic nature of the public Internet, traffic in this area needs to be migrated to private channels; otherwise, there will be delays in key communications services and applications. Service providers and their users can transmit traffic of key services through these private channels, and transport the less important traffic through the public Internet. This requires the ability of SDN technology to respond to all kinds of requests. SDN enables the network to be automatically and intensively managed, which can be achieved through remote configuration and management. The time to manage data center switches and USB device profiles by manpower have passed, IoV requires providers to rapidly configure devices around the world. That's why centralized management points will be essential components of the solution.
