The application provides a task vehicle task offloading method and device in cellular vehicle networking, belongs to the technical field of cellular vehicle networking, and aims to minimize the total task
processing delay to establish a task offloading optimization model; the task offloading optimization model is solved to obtain the optimal roadside unit
server computing frequency, the optimal auxiliary computing vehicle computing frequency, the data
packet transmission frequency between the task vehicle and the auxiliary computing vehicle, and the optimal offloading ratio matrix is calculated; and the tasks offloaded to the roadside unit
server and the auxiliary computing vehicle are distributed according to the optimal offloading ratio matrix. The application considers the distributed transmission and resource semi-persistent scheduling characteristics, models the task offloading optimization model, the task vehicle can offload the task to the auxiliary computing vehicle through the PC5 interface or offload the task to the VEC
server through the Uu interface, and then the task
processing delay is reduced; without dense
base station coverage, the complexity and cost of task offloading and
resource allocation are reduced, and the adaptability is high.
