With the continuous development and advancement of technology,people’s living standards have gradually improved,and more and more people own vehicles.Vehicles on the road must be connected to the network,and the Internet of Vehicles network will face extremely high-performance requirements.People are becoming more and more dependent on in-vehicle applications such as wireless VR,autonomous driving,and augmented reality.Such applications have the characteristics of delay sensitivity,large amount of data,and large computing requirements.Therefore,it puts forward higher requirements on the communication capabilities and computing capabilities of the Internet of Vehicles.The millimeter wave is in the frequency band of 30-300 GHz and has rich bandwidth resources.Applying it to the Internet of Vehicles will greatly improve the communication performance of the existing Internet of Vehicles networks.This article will start from the research on the collaborative technology of communication and computing in 5G Internet of Vehicles,then analyze the characteristics of millimeter wave communication technology in Internet of Vehicles,and finally study the collaborative technology of communication and computing in 5G Internet of Vehicles integrated with millimeter wave communication.First of all,in the 5G Internet of Vehicles,this paper studies the collaborative technology of communication and computing.This article uses the architecture of mobile edge computing to move computing resources from the cloud to base stations that are closer to users.In order to utilize the computing resources of the base station and the vehicle itself,this paper proposes a new service processing model,which allows the service requested by the vehicle to be split into two sub-services at any ratio and processed by the base station and the vehicle.At the same time,at the base station and vehicle,data transmission and processing can be parallel.Finally,an optimized model of communication and computing collaboration is established.Numerical simulation shows that the scheme proposed in this paper can effectively shorten the service completion time.Secondly,this paper analyzes and studies the millimeter wave communication technology in the millimeter wave vehicular network in detail.Due to the high-speed movement of vehicles,the topology of the millimeter wave vehicular network changes rapidly,and its communication environment is complex and changeable.For the first time,this paper comprehensively considers factors such as vehicle movement,obstruction of obstacles,short communication distance,and communication-related time,and deduces millimeter-wave communication probability and millimeter-wave communicationrelated time.Based on this,the concept of effective millimeter-wave communication data volume is proposed.This will bring certain help to the communication technology research of millimeter wave vehicle networking.Finally,in the 5G vehicular network integrated with millimeter wave communication,this paper studies the collaborative technology of communication and computing.First,a collaborative mechanism for vehicle 5G communication and millimeter wave communication is proposed.The vehicle periodically informs the base station of information such as position and motion status.The base station informs the relevant vehicles to establish a millimeter wave communication link through centralized scheduling and the link is established using a beam-forming technology.In addition,this article uses the millimeter wave relay technology,and puts forward the millimeter wave communication network and demand topology.Then the paper comprehensively considered the factors such as vehicle movement,occlusion,millimeter wave communication distance and communication related time,and then made joint decisions on millimeter wave relay vehicle selection,offloading ratio,and computing resource allocation.Experiments show that the proposed scheme can effectively shorten the service completion time.This article also gives the relationship between service inputoutput ratio,service calculation complexity,computing resources and offloading ratio.
