Abstract: 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.
