摘　　要：计算卸载和切换是提升车载边缘计算的计算性能和服务质量的关键问题。但由于车辆的移动性,可用计算资源的动态性变化将会导致卸载场景不断变化,进而导致任务完成时间增加。为此,提出基于计算资源动态可用性的计算卸载切换策略,包括在路径固定情况下上传目标服务节点的选择策略和基于动态可用计算资源的切换策略。实验结果表明,相对于现有研究,所提策略能够有效地缩短任务完成时间,提升计算卸载性能。Computing offloading and handoff are key issue to improve the computing performance and quality of service of vehicle edge computing.Due to the dynamic changes of vehicle mobility and available computing resources,the offloading scene will continually change,which will increase the task completion time.For this reason,a computing offloading and handoff strategy based on the dynamic availability of computing resources is proposed,including a selection strategy of the upload target service node under the fixed path and a computing handoff strategy based on dynamic available computing resources.The experimental results show that compared with the existing researches,the proposed strategy can effectively shorten the task completion time and improve the computing offloading performance.
