Security and Communication Networks has retracted the article titled “Blockchain-Based Dangerous Driving Map Data Cognitive Model in 5G-V2X for Smart City Security” [1] due to concerns that the peer review process has been compromised.
Following an investigation conducted by the Hindawi Research Integrity team [2], significant concerns were identified with the peer reviewers assigned to this article; the investigation has concluded that the peer review process was compromised. We therefore can no longer trust the peer review process, and the article is being retracted with the agreement of the Editorial Board.
The authors do not agree to the retraction.
