Problems solved by technology

[0003] However, considering the density and mobility of networked vehicles, if all networked vehicles directly communicate with the Remote Radio Header (RRH, Remote Radio Header), a large amount of communication resources will be occupied, and the accuracy of communication will also be affected. Affected, communication efficiency is not high

Abstract

The invention provides an Internet of Vehicles efficient communication method based on a cloud wireless access network architecture and related equipment, and the method comprises the steps: a cluster head vehicle of a vehicle cluster is generated based on a similarity propagation cluster head vehicle selection mechanism according to the similarity between vehicles in the vehicle cluster, and continuous iteration responsibility parameters and feasible parameters between the vehicles; the cluster head vehicle establishes wireless communication connection with a radio frequency remote end, and other common vehicles except the cluster head vehicle in the vehicle cluster establish wireless communication connection with the cluster head vehicle; in response to determining that the common vehicle drives out of the communication radius of the cluster head vehicle, the common vehicle disconnects the wireless communication connection with the cluster head vehicle and becomes a cluster-free vehicle; and in response to determining that the cluster-free vehicle enters the communication radius of the target cluster head vehicle, the cluster-free vehicle establishes wireless communication connection with the target cluster head vehicle. And the vehicle always keeps efficient wireless communication with the cluster head vehicle in the driving process, so that the network communication efficiency of the Internet of Vehicles is improved.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to an efficient communication method for Internet of Vehicles based on a cloud wireless access network architecture. Background technique [0002] In order to solve the network problems faced by networked autonomous driving, technologies such as ultra-dense networking, large-scale antennas, cloud wireless access (C-RAN, Could Radio Access Network), short time slots, and new air interfaces have been proposed in 5G networks. Among them, C-RAN technology is considered to be one of the important solutions to the problems faced by 5G networks. [0003] However, considering the density and mobility of networked vehicles, if all networked vehicles directly communicate with the Remote Radio Header (RRH, Remote Radio Header), a large amount of communication resources will be occupied, and the accuracy of communication will also be affected. Affected, the communic...
