Embodiment 1
[0080] In response to the problem of repeated transmission of large amounts of data in the Internet, in the drone communication network, caching technology can make users more efficient by placing some popular content on edge nodes such as drones and users closer to the user in advance. Get content quickly and easily. The purpose of the present invention is to provide a collaborative cache placement method for drones and users in order to effectively reduce the time delay of user content acquisition in the entire network. For a communication network composed of drones, users, and ground base stations, both drones and users have cache capabilities. Through the joint optimization of the drone and user cache, the cache content of the drone is used to guide the user’s caching decision. At the same time, by adjusting the content of the UAV cache according to the user's cache decision, the best storage content of the cache nodes based on different locations in the overall network env...
Embodiment 2
[0123] The embodiment of the invention also discloses a coordinated buffer placement device between a drone and a user in a drone communication network. The following briefly introduces the structure and composition of the UAV and user collaborative cache placement device, which is deployed on the macro base station to optimize the content cache of all UAVs and users in the network. The device includes: optimal cache placement processor for drones, optimal cache placement processor for users, and optimization control processor.
[0124] The UAV's optimal cache placement processor is connected with the user's optimal cache placement processor and optimized control processor. According to the user cache placement information input by the optimization control processor, the ADMM (Alternating Direction Multiplier Method) is used to obtain the optimal UAV cache placement information at this time, and this information is input into the user's optimal cache placement processor.
