Blockchain-Based Incentive Mechanism for Spectrum Sharing in IoV

Abstract

In this paper, we design a blockchain-based incentive mechanism for the problem of low-level participation of primary users caused by location privacy leakage during spectrum data sharing in the Internet of Vehicles (IoV). First, we propose a K -anonymous location protection scheme for multiuser cooperation, which can protect the location privacy of primary users by generalizing their location information through the construction of anonymous areas. Then, we design an incentive mechanism, which performs reporting and adjudication strategy through the transaction stored in blockchain. Simulation results indicate that the proposed scheme can effectively prevent the privacy leakage of primary users’ location and encourage them to actively participate in spectrum sharing in IoV.

Blockchain-Enabled Internet of Vehicles Applications

“…The author of Ref. [101] adds blockchain to privacy protection to ensure that location privacy is not disclosed. At the same time, the work designed an incentive scheme to encourage more vehicles to participate in the network through credibility and virtual currency.…”

“…Refs. [100,101] and other schemes proposed to take advantage of the good performance of blockchain in digital currency, introduce blockchain into the incentive mechanism, and use economic incentives to increase the participation of vehicles. However, the current research takes motivation as an additional research, and there is little special consideration on motivation, so this direction is also more challenging.…”

Security Challenges Facing Blockchain Based-IoV Network: A Systematic Review

“…The rapid increase in automobiles has led to the overuse of spectrum resources. To address this, a multiuser k-anonymous location protection method was proposed by Hongning Li et al in [11]. The system preserves users' location privacy by creating anonymous zones and encouraging primary users to share spectrum.…”
