Embodiment

[0101] The illustrations provided in the following examples and the setting of specific parameter values ​​in the model are mainly to illustrate the basic idea of ​​the present invention and to simulate and verify the present invention. In specific application environments, appropriate adjustments can be made depending on actual scenarios and requirements.

[0102] In this invention, a cell network is considered, including 500 UAV base stations. Each small base station serves users by sharing a channel in each time slot, and each time slot user is only connected to one of the UAV base stations. Given the initial emission energy state and the initial distance state, they are randomly distributed in 0.1J#E i (0)0.5J, 80m#D i (0)150m. The total energy storage of all drones is set to 50J. The data transmission of the communication link is affected by Gaussian white noise with a mean value of 0 and a variance of 1.

Abstract

The invention discloses an air-to-ground wireless communication method of multiple unmanned aerial vehicles based on discrete average field game, for the multi-UAV downlink communication system with UAV as air mobile base station, a discrete-time mean-field game model is established to describe the dynamic equation of interaction with other members based on group state averaging, and the joint optimal control of power and speed is obtained by continuous iterative updating, which solves the problems of low success rate and energy efficiency of communication links in the prior art.

Description

【Technical field】 [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a multi-UAV air-to-ground wireless communication method based on discrete mean field game. 【Background technique】 [0002] In recent years, various advantages of UAVs in potential military and civilian applications, such as low cost, strong adaptability, flexibility and convenience, have attracted widespread attention. Especially in emergency communications, UAVs can act as base stations for air-to-ground communication with ground users. When dealing with more complex situations, it is necessary to deploy ultra-dense UAV groups. However, it cannot be ignored that the communication performance of a multi-UAV system is limited by the complex interactions between a large number of UAVs and their own limited energy. Therefore, it is a serious challenge to adopt effective methods to improve the connection success rate of communication links. [0003] Gam...
