specific Embodiment
[0132] This embodiment simulates a method for safely unloading tasks based on time delay minimization and an existing mechanism based on the same network parameters in an air-ground integrated vehicle network to verify the superiority of the method of the present invention. The specific steps are: the transmission power of the vehicle is 0.25 watts, the transmission power of the drone is 1 watt, the number of edge servers installed on the drone is 5, the number of vehicles is 0-60, the computing resource of the drone is 20GHz, and the task size It is 10MB, the task generation frequency is 30s / one, and the maximum delay allowed for task processing is 10s. The result is the average value after 10,000 simulations.
[0133] Combine the present invention with ground-based vehicle networking (task offloading method adopts the present invention), vehicle / edge server share calculation (half of the task is processed on the edge server, and half is processed locally, that is, λ i,j =0.5...
