摘　　要：在构建无人机辅助车联网过程中,为解决无人机有限的能量与计算能力导致现有的平铺式逐个服务点的覆盖策略效率较低的问题,基于无人机的可视距通信和快速移动的特点,提出一种并行的计算任务传输与处理优化策略。无人机在获得计算任务后直接飞往下一个服务点,在飞行的过程中同时进行任务处理,无人机的飞行轨迹和任务调度策略被联合优化。设计了一种双层优化求解算法,重点考虑了待处理任务的优先级。仿真结果表明:并行任务传输与处理优化策略在无人机的服务能效和任务处理效率上优于传统的平铺式无人机覆盖策略,更加适合智能交通系统的应用需求。To address the increasing of computation demands of internet of vehicles(loV)users due to the sudden traffic congestion,unmanned aerial vehicles(UAVs)are introduced to the intelligent transportation systems(ITS)to construct an UAV-assisted IoV network.The UAV limited energy and computing resources lead to the current traditional UAV coverage strategy with one by one less efficiency.We propose a parallel task transmission and processing optimization strategy,considering the line-of-sight communication links and fast moving characteristics of UAV.Afier receiving the tasks from vehicles in the service point,UAV can fly to the next point and perform task processing while flying,both the UAV flight trajectory and task scheduling strategies are optimized jointly.We design a two-layer optimization solution algorithm,the prioritization of pending tasks is considered mainly A set of simulation results show that,compared with the traditional UAV coverage strategy,the proposed parallel task transmission and processing scheme is more suitable for ITS application requirements,in terms of UAV service energy efficiency and task processing efficiency.
