Unmanned aerial vehicle circling radius optimization method based on heuristic algorithm

Abstract

The invention discloses an unmanned aerial vehicle circling radius optimization method based on a heuristic algorithm. The method comprises the steps that an unmanned aerial vehicle base station provides communication coverage for a target area; the unmanned aerial vehicle base station circles over a target area to provide wireless services for ground users; the number, location and QoS requirement of the ground users are reported: the unmanned aerial vehicle acquires the circling height of the unmanned aerial vehicle through the QoS requirement, and the circling period is divided according tothe number of the users; the unmanned aerial vehicle allocates time slots to the users: the unmanned aerial vehicle uses the heuristic algorithm to jointly optimize the time slot allocation scheme ofthe ground users and the circling radius of the unmanned aerial vehicle; the unmanned aerial vehicle feeds back the time slot allocation result to the ground users; an unmanned aerial vehicle base station forwards the time slot allocation scheme to the ground users, and the unmanned aerial vehicle circles with the optimal radius; the ground users access the unmanned aerial vehicle network; and the users successively access the network in time slots according to the time slot allocation scheme of the unmanned aerial vehicle until all users complete communication. The method provided by the invention has the advantages of quick optimization of the circling radius of the unmanned aerial vehicle and good user fairness.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle communication, in particular to a heuristic algorithm-based method for optimizing the circling radius of an unmanned aerial vehicle. Background technique [0002] In recent years, miniaturized UAVs have played an important role in both military and civilian fields, such as emergency communications, data collection, patrol monitoring, resource exploration, personnel monitoring, etc. Search and rescue, etc., have aroused widespread concern. Especially in the military field, UAV combat is considered to be a new combat mode that subverts the existing combat mode, which has attracted widespread attention worldwide. The Science and Technology Committee of the Central Military Commission and the US Defense Advanced Research Projects Agency (DARPA) have established Related research projects aimed at forming the combat capability of unmanned systems. At the same time, drones are also cons...

Problems solved by technology

[0006] In short, the problem existing in the existing technology is: in the UAV base station coverage communication, the coverage of a single UAV base station is limited. When covering a large area, if the UAV is fixed at one point for communication, it cannot meet all requirements. user needs
