With the rise of smart city applications, accessibility users' location data by devices has increased significantly. However, this poses a privacy concern as attackers can deduce personal information from raw data. In paper, we propose framework to collect user while ensuring local differential (LDP) in last-mile delivery system Unmanned Aerial Vehicles (UAVs) within an edge computing environment. Firstly, obtain distribution Quad-tree employing region partitioning method based on retrieval specified collection area. Next, matrix is retrieved obtained Quad-tree, and perturb using LDP perturbation scheme matrix. Finally, collected aggregated blockchain evaluate utility dataset various regions. Furthermore, validate effectiveness our real-world scenario, conduct extensive simulations datasets multiple cities with varying urban densities mobility patterns. These not only demonstrate scalability approach but also showcase its adaptability different environments demands. research opens new avenues for future work, including exploration more sophisticated mechanisms that offer higher levels without significantly compromising quality service. Additionally, integration emerging technologies such 5G beyond environment could further enhance efficiency reliability UAV-based systems, offering challenges opportunities privacy-preserving analysis.

Three-dimensional UAV path planning is crucial in practical applications. However, existing metaheuristic algorithms often suffer from slow convergence and susceptibility to becoming trapped local optima. To address these limitations, this paper proposes a multi-strategy integrated artificial protozoa optimization (IAPO) algorithm for 3D planning. First, the tent map refractive opposition-based learning (ROBL) are employed enhance diversity quality of initial population. Second, algorithm’s autotrophic foraging stage, we design dynamic optimal leadership mechanism, which accelerates speed while ensuring robust exploration capability. Additionally, during reproduction phase algorithm, update positions using Cauchy mutation strategy. Thanks heavy-tailed nature distribution, less likely become optima exploration, thereby increasing probability finding global optimum. Finally, incorporate simulated annealing into heterotrophic stages, effectively preventing getting reducing impact inferior solutions on efficiency. The proposed validated through comparative experiments 12 benchmark functions 2022 IEEE Congress Evolutionary Computation (CEC), outperforming nine common terms accuracy. experimental results also demonstrate IAPO’s superior performance generating collision-free energy-efficient paths across diverse environments.

This paper presents an offline optimal trajectory planning method for powered parachutes (PPCs) using dynamic model simulations, emphasizing their potential in applications such as remote sensing and aerial delivery systems. A six-degrees-of-freedom (6-DOF) of the PPC is developed, complemented by a novel optimization technique called Incremented Genetic Algorithms (IGA). IGA improve computational efficiency dynamically increasing number variables only when goals are unmet, eliminating need to predefine input variable counts. approach significantly reduces time CPU usage while maintaining cost-effectiveness 3D planning. The proposed was validated on three trajectories under diverse constraints, including time, position, predefined obstacles. results demonstrate that can effectively generate single control parameter (the parachute steering angle) minimal points, showcasing its practicality efficiency.

In recent years, interest in drone-based logistics has grown due to the increasing demand for efficient and sustainable package transportation, driven by expansion of e-commerce rising environmental awareness. this study, we focus on flight scheduling transportation packages between bases, rather than last-mile delivery. scenarios where number handled at each base varies, can be achieved having drones visit high-demand bases more frequently. To end, consider a system with two types drones: local that all express only selected bases. We formulate problem as mixed integer linear programming (MILP) model minimizes total time. This simultaneously determines which should visited frequently computes schedules enable Unlike existing models assume fixed routes, our allows flexible routing, including direct flights loop-based paths ensure scalability, also propose an approximation method significantly reduces computational cost. As increases, exact solution MILP becomes intractable. Therefore, pre-select candidate based volume spatial layout, thereby reducing decision variables. makes it possible compute high-quality solutions even large-scale environments.
