The low cost, fast deployment, and flexible network topology of mobile networks with flying base stations (FlyBSs) make the FlyBSs a promising solution for ubiquitous communications in next generation mobile networks. However, an agility of the FlyBSs intensifies interference, which results in a notable degradation in throughput of cell-edge users. In this paper, we introduce a flexible soft frequency reuse (F-SFR) that enables a self-organization of a common SFR. Thus, the proposed F-SFR can handle an unpredictable and a dynamic topology of the networks with FlyBSs. To this end, we propose a graph theory-based algorithm for allocation of resources, which is understood as a bandwidth allocation and a transmission power setting in the context of SFR. We show that the proposed F-SFR can achieve 16% to 26% improvement in the throughput of the cell-edge users and improves the satisfaction of the cell-edge users up to 25% compared to the state of the art SFR solutions. We also demonstrate that the proposed scheme ensures a higher fairness in throughput among the users.
