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

Abstract

The invention discloses an Internet-of-Vehicles data transaction method based on a block chain, which comprises the following steps: establishing a data transaction network topology structure based onan alliance block chain, wherein the data transaction network topology structure comprises: a plurality of vehicles which have locally stored vehicle data and are in communication connection with anauthorized edge server; a plurality of edge servers which comprise edge layers and block chain layers, wherein the edge layers are used as transaction agents, and a bidding process of inter-vehicle data transaction is executed by adopting a double auction mechanism; by taking the block chain layers, forming a block chain network, running the intelligent contract, and providing data agent storage,calculation support of a bidding process and consensus of the block chain intelligent contract for the edge layers; and establishing a first objective function by taking buyer utility maximization, seller cost minimization and social welfare maximization of a transaction agent as market balance, and obtaining the optimal solution of the first objective function. According to the invention, a safeand real mode is provided for data transaction in the Internet of Vehicles.

Description

technical field [0001] The invention relates to the field of the Internet of Vehicles, in particular to a blockchain-based data transaction method for the Internet of Vehicles. Background technique [0002] Due to its great research value and commercial benefits, the Internet of Vehicles has attracted more and more attention from academia and industry. In particular, data transactions in connected vehicles are believed to benefit commercial entities, creating new revenue streams. As more and more entities join the business chain of the automobile life cycle, data transactions in the Internet of Vehicles have the following characteristics: 1) Multi-party participation in the data transaction process (such as: data provider, data buyer, data sender and insurance companies); 2) The conflict of interest between the parties involved makes no one party can be truly trusted; 3) Data transactions only rely on the guarantee and credit of both parties, which increases the entry thres...
