Novel Game-Theoretical Approach in Blockchain-Aided Communication at Internet of Drones

Abstract

Advances and growth of the Internet of Drones (IoD) allow devices, applications, and people to communicate and share data, improving comfort in daily life, commercial, and search-and-rescue operations in smart cities. This article investigates security issues in the IoD by considering both physical threats and mainly cybersecurity threats. Blockchain is considered as a promising technology for tackling security threats in IoD. Nevertheless, many distributed ledger systems do not have any low transaction latency, because the consensus protocols have to synchronize the whole blockchain. This article presents a novel game-theoretical approach, Stackelberg-followed Nash Game, for multirobot task allocation via secure communications in IoD.Finally, several challenges and future research trends are discussed about blockchain applications in uncrewed aerial vehicles.
