    Abstract

    In this paper, we propose and analyze the security performance of cooperative power-domain non-orthogonal multiple access systems (NOMA) for multiple users with the assistance of UAV over Rice fading channels. In the proposed system, multi-destination users are allocated various powers and communicate with the transmitter (Tx) via the UAV relaying node. UAV acts as an intermediate node that transmits the signal to the user through the amplification and forward (AF) protocol. A friendly jammer node interferes with the received signals at eavesdroppers to enhance the system’s security. In addition, in order to increase the security quality of the system through both secrecy capacity, in this paper, a multi-objective optimization technique NSGA-II is applied to maximize the secrecy capacity at the valid users and minimize the received signal’s quality at the eavesdropping node. Finally, we analyze the influence of critical system parameters on secrecy performance, such as transmit power, distance of UAV from the ground, and distance between friendly jammer and base station.
