A resource provision method for UAV-assisted edge computing based on improved DPoS consensus mechanism

With the proliferation of IoT devices and the widespread adoption of 5G technology, UAV-assisted edge computing (UAVAEC) architecture is rapidly expanding. However, the openness of wireless communication links renders the network vulnerable to malicious attacks, making security a significant concern in UAVAEC scenarios. We propose a blockchain-based approach for resource provisioning in UAVAEC architecture, ensuring secure network communication. To solve the service response latency of IoT terminals rendered by blockchain consensus process, this article adopts an offline strategy when recording the resource allocation process and crucially introduces an improved DPoS consensus mechanism. This mechanism aims to make the blockchain lightweight, and make the entire system run more efficiently in the UAVAEC environment. To strike a balance between efficiency and decentralization, we have designed an improved transaction authentication procedure centered around the competition for accounting rights. Extensive simulation experiments confirm the performance of our proposed algorithm. Compared to benchmark algorithms, it achieves higher throughput, lower block generation delay, and greater utility for candidate nodes.
