Lightweight Reputation Management for Multi-Role Internet of Vehicles

With the rapid development of the Internet of Vehicles (IoV), smart vehicles can fulfill multiple roles in either the information-centric IoV or the task-oriented IoV. However, malicious vehicles may undermine the trustiness of vehicles towards each other, and further damage these IoV networks. Given the multiple roles undertaken by vehicles in IoV networks, we aim to design a lightweight reputation-based mechanism for a hybrid IoV network in this article. This mechanism can realize real-time reputation updates and synchronization in the device-edge-cloud continuum. Simulation is conducted to validate the reputation management strategy in this article. We also discuss some opportunities and challenges to shed a light on the future research directions in this topic.
