A method for information sharing of Internet of Vehicles based on block chain architecture

Abstract

The invention discloses a method for sharing information on the Internet of Vehicles based on a blockchain architecture. In the method, vehicle users are encouraged to become Provider user nodes, and high-quality and reliable Internet of Vehicles information is shared for other users in the area. Consumer users in the area The node pays rewards to the provider user node according to the validity of the information provided by the provider user node. This method allows the vehicle user to effectively obtain the information of the Internet of Vehicles in the area where the RSU deployment of the roadside unit is lacking. Management control can solve the problem of excessively long system response time in a fully distributed network, and meet the low-latency requirements of the Internet of Vehicles for information transmission. According to the regional network environment, set the access threshold of Provider user nodes to reduce the message of the overall system network. It can effectively reduce the transmission of useless information and repeated information while avoiding network information congestion in local areas, and meet the high reliability and real-time requirements of IoV users for road traffic IoV information.

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
