Efficient Deployment of User Satisfaction Optimization in Multi-UAV Networks

In this paper, we study the deployment of unmanned aerial vehicle mounted base stations (UAV-BSs) in 3D space. We model the deployment problem as a user satisfaction maximization problem and propose an algorithm for serving non-uniformly distributed ground users outdoors. This algorithm can avoid serving too many ground users (GUs) per UAV-BS, thereby increasing the allocated data rate of ground users. Therefore, limiting the number of GUs served by each UAV-BS will improve user satisfaction. Preliminary simulation results show that our proposed algorithm improves user satisfaction by 19% compared to the existing counterclockwise spiral deployment method.
