Unmanned Aerial Vehicles (UAVs) based Base Stations(BSs) are currently considered devices that help improve network performances in wireless communication networks. They have unique features such as flexible deployment and adaptive altitude to provide communication support for ground users. Although UAVs have the above advantages, deploying UAVs in real-time has some challenges. The biggest concern is energy limitations due to the limited size of batteries. In this thesis, solar-powered UAVs are considered to support ground user communications by providing a stable connection and overcoming energy limitations. Therefore, the transmission power of the communication unit in each UAV is adaptively adjusted to support ground users. Compared to the constant power consumption, the adaptive power allocation has increased the UAV flying time by 5%. Furthermore, to extend the UAV power allocation in more realistic scenarios, the vehicle density of the ground users is predicted using Long Short-Term Memory (LSTM) neural networks. With the predicted vehicle density, linear and nonlinear optimization functions are further devised to allocate the minimum number of UAVs to support ground communications. Finally, the simulation results demonstrate that the proposed nonlinear optimization approach can reduce the required number of UAVs by 20% compared to linear optimization.
