Abstract

In this paper, we study the multi-UAVs network which acts as the relays to assist ground mobile devices (MDs) to communicate. In this scenario, the MDs are outside the coverage of cellular networks, therefore, the UAVs need to share the spectrum resources with the cellular users (CUs). In order to solve the problem of spectrum sharing between the UAVs and the CUs, we model the spectrum sharing problem as a marriage problem, and propose a one-to-one matching method to get a one-to-one stable matching between the UAVs and the CUs. The simulation results show that the proposed scheme is obviously superior to the random matching scheme and can improve the throughput of the system. Meanwhile, the UAV can achieve higher utility as the number of the CUs increases.
