The invention relates to a joint task unloading and resource optimization design method in a communication-sensing-calculation integrated internet of vehicles, and belongs to the technical field of
wireless communication. In the scheme, a task vehicle carries a communication-sensing integrated
system, and needs to cooperatively complete a large task and independently complete respective sensing tasks; large-scale tasks can be split into a plurality of
sequence dependent medium-scale tasks, and task vehicles can select local
processing or unloading to service nodes. According to the method, an efficient task unloading and
resource allocation algorithm is jointly designed, and an unloading strategy X, a power allocation strategy P and a
bandwidth allocation strategy B are optimized, so that the maximum sub-task splitting number constraint, the maximum
bandwidth constraint, the maximum transmitting power constraint, the vehicle communication
range constraint and the vehicle
radar sensing threshold constraint are satisfied; and the time
delay of a large task is minimized.
Simulation results show that the sensing performance is considered, the
processing time
delay of the large chain task in the communication, sensing and calculation integrated Internet of Vehicles is effectively reduced, and the method has very high application value and practical significance.
