Description

technical field [0001] The invention belongs to the technical field of cognitive radio and unmanned aerial vehicle communication, and in particular relates to a collaborative data distribution method in an air-ground fusion communication network. Background technique [0002] Nowadays, the rapid increase of wireless communication traffic and the shortage of wireless spectrum resources have brought great challenges to the development of wireless communication networks. Traditional terrestrial wireless communication networks are increasingly difficult to cope with the increasing mass of multimedia services, as well as the dynamic changes and uneven distribution of mobile users. The flexible deployment capability of UAVs and the ideal characteristics of air-to-ground direct links make UAV communication a promising communication method, effectively making up for the shortcomings of ground wireless communication networks. The air-ground integrated communication network provides ...
