This paper studies unmanned aerial vehicle (UAV)-aided nonorthogonal multiple access
(NOMA)-based mobile-edge computing (MEC) in Internet of Things (IoT) systems in which …

In this paper, we investigate the system performance of multihop energy harvesting (EH)
wireless sensor networks (WSNs) with imperfect channel state information (CSI) using …

In this article, we study novel wireless powered cognitive nonorthogonal multiple access
(NOMA)-based Internet-of-Things (IoT) relay networks to improve the performance of a cell …

In this work, we consider a base station (BS) mounted on an unmanned aerial vehicle (UAV)
called as an aerial BS (ABS). The ABS is equipped with multiple antennas to assist two pairs …

Wireless power transfer (WPT) is an effective way to prolong the lifetime of the energy-
constraint networks. In this paper, we investigate a wireless powered cooperative non …

The integration of non-orthogonal multiple access (NOMA) technology and cognitive radio
networks (CRNs) promises to enhance the spectrum utilization efficiency of 5G and beyond …

In order to extend the communication coverage and improve system performance, the
applications of unmanned aerial vehicles (UAVs) in wireless communications have attracted …

Recently, non-orthogonal multiple access (NOMA)-enabled cognitive satellite-unmanned
aerial vehicle (UAV)-terrestrial networks have attracted extensive attention for the …
