The invention discloses an unmanned aerial vehicle position deployment and ground cooperative forwarding method, which comprises the following steps: firstly, setting unmanned aerial vehicle and static ground user parameters in an air-ground network, and establishing a communication environment model; establishing a cooperative relationship between the unmanned aerial vehicle and the ground users and between the ground users; and finally distributing the joint strategy to the unmanned aerial vehicle and the user in a centralized manner. Or the deployment strategy is distributed to the unmanned aerial vehicle in a centralized manner, and the ground user updates the forwarding strategy in a distributed manner; and finally, an air-ground joint task of unmanned aerial vehicle deployment and user forwarding is completed. The invention focuses on the frontier application background of air-ground combination, studies the joint decision-making method of multi-unmanned aerial vehicle position deployment and ground user forwarding cooperation, and can effectively improve the proportion of effective service users; different from a spatial self-adaptive algorithm, the local spatial self-adaptive algorithm provided by the invention does not need to traverse a decision space, so that the algorithm complexity is greatly reduced while the convergence and optimality of the algorithm are ensured.
本发明公开了一种面向无人机位置部署与地面协作转发方法,首先设定空地网络中无人机和静态地面用户参数,建立通信环境模型;然后建立无人机与地面用户以及地面用户间的协作关系;最后集中式分发联合策略至无人机与用户;或集中式分发部署策略至无人机,地面用户自行分布式更新转发策略;最终完成无人机部署与用户转发的空地联合任务。本发明聚焦空地联合这一前沿应用背景,研究多无人机位置部署与地面用户转发协作的联合决策方法,能够有效提高有效服务用户占比;不同于空间自适应算法,本发明提出的局部空间自适应算法无需遍历决策空间,在保证算法收敛性和最优性的同时极大地缩小了算法复杂度。
