Abstract

The embodiment of the invention discloses a SDN-based Internet of Vehicles cloud system s. The SDN-based Internet of Vehicles cloud system comprises a global SDN control module, a local SDN controllermodule, a cloud center module, a fog server module, a middleware module and a bottom layer node module, wherein the global SDN control module is used for managing service orchestration of the local SDN controller; the local SDN controller module is used for allocating local network resources and controlling service requirements of all RSUs and terminal vehicles in a local area; the cloud center module is used for managing global resources of the Internet of Vehicles, including resource storage allocation, network management, security authentication and virtual management, so that a user can have flexible and convenient services as required; the fog server module is used for data processing and analysis of the local area; and the middleware module is used for connecting the global SDN control module, the local SDN controller module and the bottom layer node module.

Description

technical field [0001] Embodiments of the present invention relate to the field of radio frequency integrated circuits, and in particular to an SDN-based Internet of Vehicles cloud system. Background technique [0002] With the continuous improvement of the architecture of the Internet of Vehicles and the continuous development of communication technology, people have put forward higher requirements for vehicle applications. The network topology of the Internet of Vehicles is updated quickly, with various communication methods, heterogeneous integration, and non-uniform interfaces. Problems such as low utilization of network resources such as equipment and spectrum, unbalanced traffic, delay caused by high mobility, and unreliable connections, etc., and these requirements have formed a severe impact on the existing architecture and quality of service (QoS). big challenge. [0003] However, when the vehicle is moving at high speed, or when the number of vehicle nodes is too ...
