Rapid optimization method of Internet of Vehicle based on fog computing

Abstract

The invention discloses a rapid optimization method of the Internet of Vehicle based on fog computing, and relates to the field of deployment and planning of the Internet of Vehicle. The optimization of a network topology structure is divided into two aspects; first of all, the network topology structure of nodes and links must be satisfied; secondly, aiming at an optimization target of the network, the requirement of the minimum total cost of network deployment must be satisfied; the problem of minimizing the cost of the entire network deployment is translated into the problem of the cost and minimum of the overall network link and network equipment; and the network is divided into three sections, the connection between a road-side unit (RSU) and fog equipment (fog), the connection between the fog equipment and a gateway (gw), and the connection between the gateway and cloud equipment; and a heuristic connection mode is used to minimize the total cost and optimize the network speed under the necessary condition of satisfying the network connection.

Description

technical field [0001] The invention discloses a fog computing-based rapid optimization method for the Internet of Vehicles, which relates to the field of network deployment planning for the Internet of Vehicles. Background technique [0002] Fog computing (Fog Computing), in which data, data processing and applications are concentrated in devices at the edge of the network, rather than stored almost entirely in the cloud, is an extended concept of cloud computing (Cloud Computing). Fog computing is not composed of powerful servers, but is composed of various functional computers with weaker performance and more dispersed functions, which penetrate into factories, automobiles, electrical appliances, street lamps and various supplies in people's material life. Fog computing is mainly based on small clouds such as personal clouds, private clouds, and enterprise clouds. Fog computing enables many services to be deployed. For example: Internet of Vehicles. The application and...

Problems solved by technology

Fog computing can provide services such as infotainment, security, and traffic guarantee in the service menu of the Internet of Vehicles. However, due to its complex network structure, it is slow to use traditional optimization algorithms for network optimization in a large-scale network environment.
