摘　　要：现今车辆计算任务量大、复杂度高、难以满足实时性需求.为解决该问题,在移动边缘计算(mobile edge computing,MEC)的背景下,提出一种半迁移卸载模式.半迁移卸载模式即在基站与车辆间加入小型微处理单元,车辆一次性将复杂的计算任务全部卸载至MEC服务器上,当车辆即将驶离通信范围临界点时MEC服务器回传已处理好的任务以提高实时性,未处理的任务随基站进行任务迁移.仿真实验结果表明,半迁移卸载模式有效降低了任务计算时延,提高了车辆与服务器之间的数据吞吐量.Nowadays vehicle computing tasks are large and complex,and it is difficult to meet the real-time requirements.To solve this problem,a half-migration offload mode is proposed under the background of mobile edge computing(MEC).The half-migration unloading mode is to add a small micro processing unit between the base station and the vehicle,the vehicle unloads all complex computing tasks to the MEC server at one time,when the vehicle is about to leave the critical point of the communication range,the MEC server returns the processed tasks to improve the real-time performance,and the unprocessed tasks migrate with the base station.The simulation results show that the half-migration unloading mode effectively reduces the task computation delay and improves the data throughput between the vehicle and the server.
