Method for collaborative implementation of contents of unmanned equipment based on coalition formation game

Abstract

The invention provides a method for collaborative implementation of the contents of unmanned equipment based on a coalition formation game. According to the invention, a spectral clustering algorithm is used for clustering of users according to similarity among users; contents on unmanned equipment are cached based on user preferences and current content popularity distribution; then according to a principle of maximizing a system utility function of the unmanned equipment, the cooperative content transmission problem of the unmanned equipment is modeled as a coalition game model, and the coalition game of the unmanned equipment is carried out; and finally, a stable coalition structure is formed through convergence. According to the method, an unmanned equipment coalition is constructed based on an coalition game algorithm, the transmission energy consumption, the user satisfaction and the system reliability of the unmanned equipment are analyzed, and a multi-unmanned equipment cooperative communication strategy is established, so the purpose of maximizing system utility is achieved.

Description

technical field [0001] The present invention relates to a technology in the field of distributed information control, in particular to a method for realizing collaborative content of unmanned devices based on a coalition formation game (Coalition Formation Game, CFG). Background technique [0002] Buffer technology is a potential technology to alleviate link congestion. For dense user scenarios, most of the existing caching work is usually performed in a static network without mobility, and the cached content is stored in a static base station on the ground. However, in areas such as ultra-dense users and high-rise buildings, static ground base stations with caching may not be able to meet the high capacity needs of users. Due to the advantages of fast and efficient, LoS link to ground nodes, and controllable movement, UAVs have high caching prospects in future wireless communications, and can be deployed as aerial base stations to assist traditional cellular networks.
