“…To maximize the covert transmission rate from the UAV to the legitimate ground user via optimizing the UAV's trajectory and transmit power, a new design framework is introduced in Reference 226, which utilizes SCA to develop an iterative algorithm. Using a UAV friendly jammer assisted by AN to enhance the NOMA‐based IoT system having imperfect CSI is investigated in Reference 227. Apart from this hybrid strategy involving cooperative relaying and jamming is also widely explored in the literature 228,229 to optimize the secrecy performance.…”

Due to the open nature of wireless communication systems, the data transmission over these networks are vulnerable to malicious attack. To safeguard the transmitted data, physical layer security (PLS) has been emerged as a promising technique because of its unique feature of utilizing randomness of the wireless channel to secure the information. The preeminent idea of utilizing the channel imperfections such as fading and noise into the security providing resource is the basic approach behind PLS. For exploiting the randomness of the propagation medium, the analysis of the secrecy performance over the fading channel is of utmost importance. With the explanation of basic theory and technology, this paper presents an elaborated survey on the PLS research over the fading channels. To exploit the performance gains, we discuss the optimization approaches in different network design problems, for example, secrecy rate maximization, power minimization, and secure energy efficiency problems. We present a comparative study of the expressions of various performance metrics of the PLS along with classification depending upon the channel state information of the eavesdropper. The application and challenges of the PLS in the emerging wireless technologies are also reviewed and discussed. This paper incorporates almost all the aspects of PLS implemented over the fading channels. Furthermore, the paper is concluded with open research directions for the PLS system in various fields that can be explored to design a flexible and robust security system to satisfy the security requirements of the next‐generation networks.

Unmanned aerial vehicle (UAV) relay system has received significant attention in future wireless communications. In this article, the ergodic sum rate of a multisource multidestination UAV relaying is investigated. Here, an UAV with multiple antennas is deployed as an aerial relay using threshold-based decode-and-forward protocol to assist signal transmission from multiple sources to their intended destinations simultaneously. By considering the effect of path loss, we first obtain the output signal-to-interference-plus-noise ratio expression for the considered system. Then, we propose a statistical channel state information based beamforming (SCSI-BF) scheme to maximize the system ergodic sum rate, where both of the uplink and downlink channels are subject to correlated Rayleigh fading. Furthermore, we derive the analytical expression for the ergodic sum rate of the considered system with the SCSI-BF scheme. Finally, numerical results are given to demonstrate the superiority of the SCSI-BF scheme and the validity of the theoretical analysis, and show the impact of various parameters on the system performance. INTRODUCTIONUnmanned aerial vehicles (UAVs) have also shown broad application prospects in the field of wireless communication due to its advantages such as low cost, easy deployment, and control. [1][2][3] Especially, in remote areas and marine communications, the line of sight (LoS) is not always available due to the long distance or obstacles. Therefore, the high-altitude relay platform can be used to establish a reliable communication link. Although satellite communication can be considered as an effective solution in this situation, [4][5][6][7] in some civil communications, it is difficult to be widely used due to the high costs of construction and maintenance. Therefore, UAV-based wireless communication technology has received more and more attention. 8,9 Related worksUAVs have been deployed as aerial base stations to provide better network coverage and more reliable communication. 10,11 Especially, in urban areas where traffic overloading often occurs or in rural areas where fixed ground infrastructure is not cost-effective. 12,13 There are also a number of surveys on UAV communication over the past few years, which are discussed here to prove the uniqueness of this survey.

UAV wireless communication has been regarded as a promising technology in the fifth-generation (5G) networks. In this paper, we consider the security of the mmWave NOMA UAV-assisted relay system, where a ground source transmits messages to two types of authorized users assisted by a UAV relay in the presence of multiple eavesdroppers. A practical probabilistic line-of-sight (LoS) channel model with Nakagami- m small-scale fading and three-dimensional (3D) antenna gain is established to describe the mmWave air-to-ground channel. In addition, to improve the security of the system, cooperative jamming and protected zone strategies are introduced. The analytical expressions of connection outage probability (COP), secrecy outage probability (SOP), and effective secrecy throughput (EST) under the NOMA scheme and cooperative jamming NOMA scheme are derived. Also, the asymptotic SOP and EST are analyzed to gain further insights. The theoretic analysis and simulation results show the effectiveness of the proposed schemes. As the transmitting power of the source and UAV relay increases, the SOP depends only on the location distribution and density of eavesdroppers and the ESTs under different schemes converge to the same floor.
