specific Embodiment

[0155] The algorithm based on distributed miner connected dominance set is verified through specific embodiments. Arbitrarily arrange car-linked social network entities in a square area whose length varies from 40 to 120 meters, and the transmission range (R) of each car-linked social network entity varies from 10 to 20 kilometers. Use N to represent the total number of nodes in the network, and its calculation method can be expressed as N=L×L×ρ, where L×L represents the area of ​​the test area, and ρ represents the node density. For example, in an area of ​​40×100 kilometers, the social network entities of the Internet of Vehicles are arranged with a node density of 0.01, then the total number of network nodes in the area is N=40×100×0.01=40. The detailed information and simulation parameters of the test scenarios are shown in Table 1. Four scenarios were designed using different parameters to test the selection of miners. The important influencing parameters include node den...

Abstract

The invention discloses a method for building a secure vehicle-linked social network based on blockchain technology. The entire network includes a three-level architecture of a main controller, a roadside unit, and a local controller (vehicle miner), and uses software-defined means to strengthen network programmable , virtualization and partitionable features, but it will cause the vulnerability of network single point failure. The invention is supplemented by block chain technology, through the system consensus mechanism design based on the trust degree algorithm and the reliable miner selection method, the transaction authentication is realized and the data anonymity is realized in a completely distributed manner to ensure the security of the system.

Description

technical field [0001] The invention relates to a method for building a social network for the Internet of Vehicles, in particular to a method for building a social network for the Internet of Vehicles that is safe based on blockchain technology. Background technique [0002] The Internet of Vehicles social network is a very promising concept, which realizes the combination of the vehicle network and the social network. In the IoV social network, vehicles are equipped with multiple sensors that can collect multiple spatiotemporal data. The social dimension of the Internet of Vehicles mainly refers to the ability to analyze, use, and share data on commuters who have the same interests or are in similar traffic situations. The Internet of Vehicles social network combines the relevant characteristics of vehicle networks and social networks. Vehicle networks provide network communication infrastructure and can be deployed in a centralized, distributed or hybrid manner. The In...
