The present invention provides a method for UAV clusters to provide communication services for ground users as air base stations, including: step 1, when it is detected that there is no base station on the ground or the ground base station stops providing communication services, start the service based on the aerial UAV. For the communication service plan, obtain the value of the algorithm parameter; step 2, obtain the value of the algorithm parameter, and use the algorithm of approximation and linear relaxation to solve the deployment plan of the UAV cluster; the deployment plan of the UAV cluster is specific Including: the location information of each UAV in the UAV cluster; step 3, according to the deployment plan of the UAV cluster, a heterogeneous communication network is formed by different types of UAV groups, so that a limited number of different A heterogeneous communication network composed of types of UAVs covers as many users as possible. The present invention can optimize the deployment position of the drones when different types of drones are used as air base stations, thereby covering the most users.
Description
technical field [0001] The invention relates to the field of UAV communication and resource management, in particular to a method for a UAV cluster serving as an air base station to provide communication services for ground users. Background technique [0002] As UAVs (Unmanned Aerial Vehicles, also known as drones) are more and more widely used in various industries, it is particularly important to study UAV communication to meet the communication needs of various applications. When UAVs perform tasks such as search and rescue, traffic For specific tasks such as monitoring and forest fire prevention, UAV is equivalent to an aerial user equipment (AUE, aerial user equipment). Each task has different requirements for delay, speed, communication range, throughput, etc. UAV Another important application in the field of communication is to cooperate with the ground base station to improve the communication network to solve the problem of communication blind spots such as tunnels...
