Abstract

This paper investigates the challenges of data trust sharing faced by Internet of Vehicles (IoV) network with 5G broadcast services. Particularly we develop a decentralized IoV reputation management model with spatiotemporal feature perception fusion (RMM-STFP) based on blockchain. The proposed reputation evaluation method evaluates the reputation value of nodes from the two aspects of time continuity and spatial transitivity and thus improves the identification accuracy of malicious nodes. To further accelerate the dissemination of reputation data, we have constructed a blockchain-based management storage system, where PBFT consensus scheme combines reputation and Bayesian inference. Finally, numerical results are given to justify the superiority of our proposed scheme. When proportion of malicious nodes reaches 45%, the accuracy of our proposed method is 94.5%, and the suppression rate of malicious messages is 83%. Moreover, compared with the traditional PBFT consensus scheme, the consensus delay and communication overhead are reduced by 87.57% and 78.45%, respectively, and the transaction throughput is increased by 70.65%.

利用 5G 广播服务增强物联网网络的分散式声誉管理模型

本文研究了具有5G广播服务的车联网（IoV）网络所面临的数据信任共享挑战。特别是在区块链的基础上，开发了一种基于时空特征感知融合（RMM-STFP）的分散式车联网信誉管理模型。提出的信誉评价方法从时间连续性和空间传递性两个方面对节点的信誉值进行评价，从而提高了恶意节点的识别精度。为了进一步加速声誉数据的传播，我们构建了一个基于区块链的管理存储系统，其中PBFT共识方案结合了声誉和贝叶斯推理。最后给出了数值结果，证明了所提方案的优越性。当恶意节点比例达到45%时，本文方法的准确率为94.5%，对恶意消息的抑制率为83%。此外，与传统的PBFT共识方案相比，共识延迟和通信开销分别降低了87.57%和78.45%，交易吞吐量提高了70.65%。

期刊介绍： The Society’s Field of Interest is “Devices, equipment, techniques and systems related to broadcast technology, including the production, distribution, transmission, and propagation aspects.” In addition to this formal FOI statement, which is used to provide guidance to the Publications Committee in the selection of content, the AdCom has further resolved that “broadcast systems includes all aspects of transmission, propagation, and reception.”
