Design And Implementation Of Information Distribution Simulation System Of Vehicular Network Based On Dynamic Micro-cloud

With the development of the Internet of Vehicles,the business in the Internet of Vehicles is also increasing,and the data exchange between vehicles and other vehicles,roads,infrastructure,pedestrians and remote cloud servers is increasing and more frequent.With the development and gradual maturity of autonomous driving technology,various applications that require a large amount of global data,such as path planning,global traffic management,vehicle information management,and traffic prediction,are constantly increasing,and many involve real-time operations.The demand for low latency requirements and high quality services such as object detection,redundant collision detection,steering braking,motion planning,behavior planning,etc.is also growing rapidly.These applications require a large amount of data to be transmitted over the network,while also requiring a large amount of data processing for low latency requirements.Based on the current situation and future development of the Internet of Vehicles and autonomous driving,this thesis analyzes and summarizes the information distribution requirements in the future Internet of Vehicles,and proposes a vehicle network information distribution simulation system based on dynamic micro-cloud.The system utilizes a remote cloud server to complete application tasks that need to process and store global big data,and exchange data between vehicles through a dynamic micro cloud formed by vehicles,so that vehicles can obtain a larger range of environmental data through cooperation between vehicles.Improve the data processing and computing capabilities of a single vehicle and complete low-latency application tasks locally.The micro cloud computing node in the micro cloud is responsible for managing vehicles in the micro cloud,controlling the cooperation between vehicles in the micro cloud,and data exchange between the member vehicles and the remote cloud,migrating complex data processing to the edge of the network,and reducing the network.Bandwidth usage and business latency.This thesis also designs an incentive mechanism to encourage vehicles to become micro-cloud computing nodes by means of integral incentives,and use their own computing and storage resources to provide services to other nodes.This thesis firstly investigates related technologies such as car networking,and analyzes the development of autonomous driving technology,the problem of the car network is about to face,and the demand for these problems is based on the dynamic micro cloud-based car network information distribution simulation system.Design,and give a detailed design,including the overall architecture,program flow,module functions and so on.Finally,the design scheme is simulated and verified,and the effectiveness of the design scheme is verified.
