Mobile edge node unloading method applied to Internet of Vehicles

The invention belongs to the field of Internet of Vehicles and mobile edge computing, and particularly relates to a mobile edge node unloading method applied to the Internet of Vehicles. Aiming at an application scene of mobile edge computing in the Internet of Vehicles, the invention provides a computing task unloading strategy optimization method for multiple mobile terminals and multiple access edge nodes, and a joint optimization strategy is adopted to enable the vehicle mobile terminals in the same Internet of Vehicles system scene to be in a multi-access edge node mode. And the total task completion time consumption of the system is reduced in the process of unloading the calculation task by the edge nodes distributed in the scene. Based on a convex optimization principle, a task unloading time consumption mathematical model based on mobile edge calculation is constructed by taking two aspects of a calculation task unloading strategy and vehicle mobile terminal propagation power as optimization thoughts
