“…The complexity of overall algorithmic framework is analyzed theoretically. Finally, the simulation results indicate that the presented scheme is superior to the state-of-the-art works [14][15][16] and benchmark scheme in terms of the sum rate. Additionally, the convergence, complexity, and performance gap caused by iterative optimization are shown.…”

“…Additionally, a drone-assisted urban emergency communication scenario was considered in [14], where a joint altitude and resource allocation scheme was proposed to ensure information forwarding from the disaster area. Currently, in order to make full use of the advantage of drone-assisted PDEComs, combining the NOMA technique with the relaying drone has attracted much attention from researchers [15,16,20,21]. The authors in [15,21] incorporated the NOMA technique with the decode-and-forward (DF) relay protocol to improve the spectrum utilization and transmission performance of PDEComs.…”

“…In scenarios where ground-based communication infrastructure may be compromised due to natural disasters or accidents, UAVs serve as agile alternatives, ensuring uninterrupted communication and operational continuity. This redundancy enhances the reliability of IoV networks, fostering safer and more efficient transportation ecosystems even in the face of unforeseen disruptions [8][9][10]. In essence, by harnessing the capabilities of UAVs as active components within IoV, rural highways stand to benefit from enhanced connectivity, resilience, and efficiency, paving the way for smarter and more sustainable transportation solutions.…”

“…In recent years, studies of MCS task allocation have become a hotspot in academia, and many novel strategies have been proposed, with the purpose of maximizing sensing quality with a limited budget [ 23 , 24 , 25 ] or minimizing incentive costs while ensuring a minimal degree of sensing quality loss [ 26 , 27 ]. However, under the diversified dynamic MCS environment, particularly in SAGSINs, allocating large-scale tasks to mobile users according to heterogeneous sensors (e.g., mobile users, UAVs [ 28 ], ships, and stationary sensors) to achieve the tradeoff between the sensing quality and sensing cost is a huge challenge.…”
