Clustering-based Internet of Vehicles multi-channel allocation method, device and equipment

Abstract

The invention provides a clustering-based Internet of Vehicles multi-channel allocation method, device and equipment. The method comprises the following steps: acquiring vehicle density information ofa current road section; determining a target communication mode corresponding to the vehicle density information according to the vehicle density information and a preset channel allocation rule, wherein the target communication mode comprises a target channel mode and a target communication radius, the preset channel allocation rule comprises a corresponding relationship between vehicle densityinformation and a channel mode and a corresponding relationship between the vehicle density information and a communication radius; and sending the target channel mode to the vehicles on the current road section, so as to enable the vehicles to communicate according to the target communication mode, thereby avoiding transmission conflicts while adapting to the density change of the vehicles, and improving the utilization rate of the channel.

Description

technical field [0001] The present application relates to the technical field of vehicle communication, and in particular to a method, device and equipment for multi-channel allocation of the Internet of Vehicles based on clustering. Background technique [0002] At present, many MAC protocols (Medium Access Control) in the Internet of Vehicles are designed for the highway model, and most cluster-based TDMA protocols are only for highway scenarios. [0003] The topology in the VANET (Vehicular ad-hoc network, Vehicular Mobile Ad-hoc Network) vehicle network can be described in terms of levels. Under the centralized topology, the base station (RSU) usually controls or manages all the vehicles in the network, and coordinates the channel access of the vehicle nodes within its coverage. In the fully distributed VANET, there is no concept of central control, and each vehicle with the same function can be used as a routing node. Protocols that access channels in a distributed fa...

Problems solved by technology

[0006] This application provides a cluster-based multi-channel allocation method, device and equipment for the Internet of Vehicles to solve the defect that the MAC protocol in the prior art allows fixed vehicles to access channels at most and cannot adapt to changes in vehicle density, especially in vehicle load distribution. The problem of low communication channel utilization under unbalanced conditions
