本研究通過使用無人機進行包裹配送，引入了一種創新的城市無人機物流方法。我們提出了一個借助區塊鏈技術支持的無人機配送場景，這不僅提高了便利性，同時也滿足了現代物流需求和消費者行為趨勢。

我們研究的核心是將Hyperledger Fabric（HLF）私有區塊鏈網路與無人機物流模型整合。這一整合對於提升數據安全、可追蹤性和透明度至關重要，特別是通過使無人機能夠在整個配送任務中持續且即時地更新飛行和包裹資訊到區塊鏈帳本。

為了最大化區塊鏈上記錄的交易總數，我們制定了一個數學規劃問題，以優化無人機群的交易提交週期，從而開發出公平無人機交易發送週期調度演算法。通過與Gurobi求解器和現有區塊鏈集成的無人機配送系統進行比較，對我們所提演算法的性能進行了嚴格檢驗。比較結果展示了我們演算法在管理交易週期和確保無人機之間公平資源利用的效率，同時不影響物流服務的安全性和可追蹤性。

研究進一步探討了系統可擴展性、通訊效率和無人機間公平交易分配之間所需的平衡。這一探討凸顯了發展複雜通訊策略以避免潛在網路瓶頸的關鍵需求。未來研究方向包括優化通訊策略、根據即時網路狀態動態調整交易間隔，以及對不同區塊鏈平台在無人機物流中的效能進行全面評估。

探索區塊鏈技術與無人機物流的結合，揭示了使城市配送系統更加高效、安全和透明的新途徑。本研究對於蓬勃發展的無人機物流領域的貢獻，強調了區塊鏈在徹底改變城市地區交付機制方面的潛力。

This study introduces an innovative approach to urban UAV logistics through the utilization of unmanned aerial vehicles (UAVs) for parcel delivery. We present a blockchain-aided UAV delivery scenario that enhances convenience while adhering to modern logistics demands and consumer behavior trends.

Central to our study is the integration of the Hyperledger Fabric (HLF) private blockchain network with the UAV logistics model. The integration is crucial for enhancing data security, traceability, and transparency, particularly by enabling UAVs to consistently and real-time update the blockchain ledger with flight and parcel information throughout their delivery missions.

To maximize the total number of transactions recorded on the blockchain, a mathematical programming problem was formulated to optimize the transaction submission periods of UAVs, leading to the development of the Fair UAV Transaction Submission Period Scheduler (FUTSPS) algorithm. Our evaluation compared FUTSPS's effectiveness to the Gurobi Optimizer's optimal or near-optimal solutions and another blockchain-based UAV delivery system, which only logs logistics info at mission start and end. The comparison demonstrates FUTSPS's ability in managing transaction periods and ensuring equitable resource utilization among UAVs, without compromising the security and traceability of logistics services.

The study further investigates the balance required between system scalability, communication efficiency, and equitable transaction distribution among UAVs. This examination highlights the critical need for sophisticated communication strategies to avert potential network bottlenecks. Future research avenues encompass optimizing communication strategies, dynamically altering transaction intervals in response to live network statuses, and conducting comprehensive evaluations of different blockchain platforms' efficacy in UAV logistics.

Exploring the integration of blockchain technology with UAV logistics sheds light on new pathways for making urban delivery systems more efficient, secure, and transparent. The contributions of this study to the burgeoning field of UAV logistics underscore the transformative potential of blockchain in revolutionizing delivery mechanisms in urban settings.
