Abstract

With the continuous development of information technology, drones have become the supporting technology for sustainable smart cities. Currently, the blockchain that guarantees the information security of the unmanned aerial vehicle (UAV) network has become the focus of academic attention. However, due to the small size of the drone, and its limited storage and battery capacity, it is difficult to support the sustainable work of the UAV blockchain network. Therefore, this paper proposes the concept of sustainable blockchain (SusChain) and empowers the UAV blockchain network to better apply it to sustainable smart cities. In particular, we have introduced and improved the Ultra-Low Storage Overhead-Practical Byzantine Fault Tolerance (ULS-PBFT) consensus in the UAV blockchain network, making it a sharding scheme with extremely low storage overhead and energy consumption. Meanwhile, we design a reptation-and-matching-based UAV clustering scheme to ensure that each shard and SusChain have a high consensus success rate. The simulation results show that SusChain has a significant advantage in the key indicators of sustainability. In specific cases, it has a 9–227%, 11–58%, and 27–56% improvement effect in consensus security, consensus delay, and energy consumption, compared to other sharding schemes.

SusChain：无人机区块链网络的可持续分片方案

随着信息技术的不断发展，无人机已成为可持续智慧城市的支撑技术。目前，保障无人机网络信息安全的区块链已成为学术界关注的焦点。然而，由于无人机体积小，存储和电池容量有限，难以支撑无人机区块链网络的可持续工作。因此，本文提出了可持续区块链（SusChain）的概念，并为无人机区块链网络赋能，使其更好地应用于可持续智慧城市。其中，我们在无人机区块链网络中引入并改进了超低存储开销-实用拜占庭容错（ULS-PBFT）共识，使其成为一种具有极低存储开销和能耗的分片方案。同时，我们设计了一种基于重定位和匹配的无人机聚类方案，以确保每个分片和SusChain都有较高的共识成功率。仿真结果表明，SusChain 在可持续性的关键指标上具有显著优势。具体来说，与其他分片方案相比，它在共识安全性、共识延迟和能耗方面分别有9-227%、11-58%和27-56%的改进效果。

期刊介绍： The aim of the Peer-to-Peer Networking and Applications journal is to disseminate state-of-the-art research and development results in this rapidly growing research area, to facilitate the deployment of P2P networking and applications, and to bring together the academic and industry communities, with the goal of fostering interaction to promote further research interests and activities, thus enabling new P2P applications and services. The journal not only addresses research topics related to networking and communications theory, but also considers the standardization, economic, and engineering aspects of P2P technologies, and their impacts on software engineering, computer engineering, networked communication, and security. The journal serves as a forum for tackling the technical problems arising from both file sharing and media streaming applications. It also includes state-of-the-art technologies in the P2P security domain. Peer-to-Peer Networking and Applications publishes regular papers, tutorials and review papers, case studies, and correspondence from the research, development, and standardization communities. Papers addressing system, application, and service issues are encouraged.
