Abstract
Nowadays, drones are widely used in many fields because of their flexibility, scalability, low cost, and easy deployment. However, their security issues are an important concern in communication networks. Blockchain, a distributed network technology, is a promising solution in providing secure, transparent, and efficient data transmission for drone systems. Moreover, edge and cloud computing can further assist blockchain-based drone systems with stronger data storage and processing capabilities. In this article, we propose a drone-assisted and blockchain-enabled edge-cloud computing network framework (DBECN), where drones can act as moving terminals and moving base stations for different scenarios, such as crowd monitoring, disaster relief, concerts, and sparsely populated area coverage. Integrated with terrestrial edge nodes and cloud centers, the framework can also provide plenty of caching and computation resources for delay-sensitive and resource-demanding task processing, and big data analysis, caching, and processing. In particular, we present a secure and credible data sharing scheme under our DBECN framework, where we deploy blockchain in the edge nodes to provide secure and efficient data storage and sharing among different terminal-based drones.
