Embodiment

[0064] 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.

[0065] The present invention considers the air-to-ground communication network of multiple UAV mobile base stations, assuming that the area to be covered by the deployment of air mobile base stations is 50×50km, and includes 8 UAV mobile base stations with different performances and 100 UAV mobile base stations in the designated service area. users, UAV base stations and users are randomly deployed initially. Each base station only serves one user in each time slot. In order to make the system simpler, we set the flight height of all UAV mobile base stations in the system to 2km, set the transmit power of the unit frequency...

Abstract

The invention aims to disclose a multi-type unmanned aerial vehicle mobile base station deployment method based on an average field pattern game. For a ground communication system with a multi-performance unmanned aerial vehicle as an air mobile base station, the influence of deployment decisions of different types of unmanned aerial vehicle mobile base stations on state evolution of the whole system is fully considered, an average field type game system model is established, and an optimal deployment scheme of the multi-unmanned aerial vehicle mobile base station is obtained through a numerical solution, wherein the performance difference of a plurality of unmanned aerial vehicle aerial mobile base stations is embodied in two aspects of flight speed and service radius, and the different parameters are introduced into an average field item to describe a state equation and a cost function of interaction with other unmanned aerial vehicle mobile base stations. The problem of high deployment energy consumption under the ground communication network of the multi-type unmanned aerial vehicle mobile base station in practical engineering application is solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for deploying mobile base stations of multi-type unmanned aerial vehicles based on mean field game. 【Background technique】 [0002] In recent years, drones have been more widely used in daily life due to their low cost and strong flexibility. As an air mobile base station, the UAV provides wireless communication coverage for ground user equipment, or serves as an additional auxiliary base station to serve ground users to increase the capacity of the wireless network. Compared with the traditional ground communication network, the UAV mobile base station can quickly establish a communication link, and change the communication coverage area and network capacity by adjusting the flight strategy of the UAV at any time. At the same time, the UAV mobile base station platform takes advantage of the air, It can better avoid obstacles and establish a...
