The invention relates to an Internet of Vehicles content cache decision optimization method, which belongs to the technical field of mobile communication. In
the Internet of Vehicles content cache decision optimization method,
the Internet of Vehicles is provided with a plurality of content cache nodes, and the content requested by a vehicle can be stored in the content cache nodes; if a nearby vehicle or a roadside unit already caches the request content of the current vehicle, the current vehicle obtains a content service from the cache node through a V2V link or a V2I link; a
mobile edge computing server is deployed on the RSU side, can provide storage and computing capabilities and is used for content storage and
processing; and due to the fact that the
moving speed of the vehicle is high, the content request vehicle cannot completely obtain the needed content within a current RSU coverage range, and therefore the content request vehicle needs to continue to obtain the remaining content within a next RSU coverage range.
The Internet of Vehicles content cache decision optimization method aims to reduce the total time
delay of acquiring the required content by the content requestvehicle. According to
the Internet of Vehicles content cache decision optimization method, the association problem of vehicles can be solved, and the content pre-caching is considered, so that the optimal content caching decision is obtained.
