We aim to develop a system-level security solution for a large-scale device-to-device (D2D)
network against adversaries based on covert communication. The D2D network underlays a …

In this paper, we investigate a nonconvex robust fractional quadratically constrained
quadratic problem (Robust Fractional QCQP), which has a wide application to the worst-cast …

This paper studies a multiple-input and multiple-output (MIMO) multi-hop decode-and-
forward (DF) relaying wireless network. Communication between a source node and a …

Robustness and energy efficiency (EE) are of crucial importance in reconfigurable intelligent
surface (RIS)-assisted wireless communication networks. However, a large portion of the …

To solve the power supply problem of battery-limited Internet of Things devices (IoDs) and
the spectrum scarcity problem, simultaneous wireless information and power transfer …

Combination with the Simultaneous Wireless Information and Power Transfer (SWIPT)
technology is expected as a promising solution to the issue of energy constraint in Wireless …

Unmanned aerial vehicles (UAVs) play a crucial role in remote environmental applications
of the Low-Power Internet of Things (IoT) network. However, the interaction between a large …

In the field of Internet-of-Things (IoT), how to enhance the computation capacity and prolong
the life span of massive smart IoT nodes is becoming a more practically important but …

This article considers a backscatter-aided wireless powered mobile edge computing (BC-
aided WPMEC) network, in which the tasks data of each Internet of Things (IoT) device can …

This study investigates the optimization of proportional fair (PF) and energy efficiency in
simultaneous wireless information and power transfer (SWIPT)-based device-to-device …
