Internet-of-vehicles information sharing method based on block chain architecture

Abstract

The invention discloses an Internet-of-vehicles information sharing method based on a block chain architecture. In the method, a vehicle user is stimulated to become a Provider user node and share high-quality and reliable Internet-of-vehicles information to other users in the area, and a Consumer user node in the area pays awards to the Provider user node according to the effectiveness of the information provided by the Provider user node. According to the method, a vehicle user can effectively obtain the Internet-of-vehicles information in an area lacking RSU deployment, an area control nodeis used for carrying out management control on the Provider user node and the Consumer user node, the problem of overlong system response time in a fully distributed network can be solved, and the requirement of the Internet of vehicles for low time delay of information transmission is met. A Provider user node admission threshold is set according to a local area network environment, the messagecommunication traffic of the whole system network is reduced, the transmission of useless information and repeated information is effectively reduced while the network information congestion in a local area is avoided, and the requirements of Internet-of-vehicles users for high reliability and real-time performance of road traffic Internet-of-vehicles information are met.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a method for sharing information of the Internet of Vehicles based on a block chain architecture. Background technique [0002] The Internet of Vehicles is a brand-new network system, mainly composed of OBU (On Board Unit) and RSU (Road Side Unit). The road side unit RSU is deployed on the road side to provide road traffic information for the Internet of Vehicles system. Whether it is on urban roads or highways, it will be a high investment to build a complete Internet of Vehicles system, especially RSU units with sufficient density, and it will be difficult to achieve full network coverage of RSUs in the short term. At the same time, there will be more and more autonomous vehicles on the road in the future. With the help of its high-precision sensing equipment and powerful computing power, self-driving vehicles can obtain the road condition information require...

Problems solved by technology

However, the sharing of road condition information of self-driving vehicles will bring certain power consumption, CPU resource consumption, privacy leakage and other problems that are harmful to their own interests, and it is difficult to operate subjectively.

[0004] In the prior art, Publication No. CN109978623 A "A Blockchain-Based Information Sharing Incentive Method for Internet of Vehicles" and Publication No. CN110648134 A "A System and Method for Close-distance Data Sharing of Internet of Vehicles Users Based on Blockchain" proposed The Internet of Vehicles information sharing reward method encourages vehicle users to share information, but it is based on one party initiating an information request and the other party providing information services. It belongs to a single point-to-point transaction and does not consider the characteristics of vehicles. Information requirements of the road network of vehicles, without considering the actual network reliability and capacity requirements, if all users participate in information provision or initiate information demand, information storms and repeated information will easily occur
