5G Internet of Vehicles vehicle reputation management method based on alliance chain

Abstract

The invention provides a 5G Internet-of-Vehicles vehicle reputation management method based on an alliance chain for a 5G Internet-of-Vehicles intelligent traffic application scene and aiming at malicious behaviors and selfish behaviors shown when a vehicle reports sensing information to a roadside base station. According to the method, a vehicle reputation model is designed, and a vehicle reputation management system based on an alliance chain is constructed, so that the requirement that vehicles actively participate in reporting real and accurate sensing information is met. According to the vehicle reputation model, on one hand, a semaphore-based reward and punishment mechanism is adopted to suppress malicious behaviors of vehicles, and on the other hand, a periodic tax mechanism is adopted to suppress selfish behaviors of the vehicles. According to the vehicle reputation management system based on the alliance chain, on one hand, a distributed management architecture meeting multi-party participation requirements of a government agency and an operator is established, and on the other hand, four basic services of user access authorization, vehicle information reporting, vehicle reputation value reward and punishment and vehicle periodic tax are realized on the alliance chain in an intelligent contract manner; the vehicle reputation value calculation basis and the safety and reliability of the calculation process are ensured, and the balance flow and long-term stability of the reputation value between the vehicle and the management party are also ensured.

Description

technical field [0001] The invention relates to the field of intelligent traffic management supported by 5G Internet of Vehicles, and is specifically applied to establishing and maintaining the reputation of vehicles in urban traffic scenarios, thereby suppressing malicious and selfish behaviors exhibited by vehicles in an intelligent traffic system. Background technique [0002] The fifth generation (5G) mobile communication technology has the advantages of high frequency, high speed and high throughput. With the improvement of technology and the comprehensive deployment of infrastructure, intelligent vehicle networking has become the most promising application field of 5G. As the core communication technology for building future intelligent transportation systems, 5G can support various applications such as collision avoidance warning between vehicles, road traffic status detection, vehicle path planning and navigation, automatic driving and unmanned driving.

Problems solved by technology

While performance is bottlenecked, the centralized solution also exposes many problems. For example, a single point of failure can easily cause serious security consequences, and poor scalability can hardly meet the needs of government agencies, network operators and other parties involved in supervision in real scenarios.
