Internet-of-Vehicles data exchange method based on block chain

Abstract

The invention provides an Internet-of-Vehicles data exchange method based on a block chain. The method comprises the following steps: enabling the vehicle-mounted sensor of an information sending vehicle node to monitor the state of the vehicle at any time; transmitting the monitored data parameters to an OBU; enabling the OBU to define various received data parameters according to protocol standards; defining the message as a universal security message, wherein the basic security message is information which must be sent when data exchange is carried out between vehicles; enabling the OB to continuously and periodically send the BSM, on the basis of WAVE protocol-based Internet-of-Vehicles multi-triangle multicast communication, achieving data exchange between vehicles through master-slave node communication, ensuring rapid and stable communication between vehicles, and then achieving data exchange between roads and between vehicles through distributed broadcasting and storage of roadside units. According to the invention, the block chain technology is used to improve the safety and stability of vehicle mutual communication in the Internet of Vehicles.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a data exchange method for the Internet of Vehicles based on block chains. Background technique [0002] The Internet of Vehicles is the embodiment of the Internet of Things technology in the field of intelligent transportation systems, and is the core of the field of intelligent transportation systems. The Internet of Vehicles is composed of multiple vehicle nodes. It collects real-time running data of vehicles through wireless data communication technology and processes them for communication between vehicles, between vehicles and roadside basic units, between vehicles and Data interaction between pedestrians, etc., so that vehicles can be better integrated into the urban network. Vehicles can collect their own surrounding environment and state information through sensors, GPS, RFID, cameras, image processing and other devices; and all vehicles can use Interne...

AI Technical Summary

Problems solved by technology

[0003] However, the existing Internet of Vehicles has problems in big data management, transparency and security, and the communication between nodes of the Internet of Vehicles cannot be guaranteed to be safe and reliable.
