The use of in-band full-duplex (FD) enables nodes to simultaneously transmit and receive
on the same frequency band, which challenges the traditional assumption in wireless …

With the advanced communication technology, the number of users and applications are
increasing exponentially leading towards the scarcity of resources and an increase in power …

In the present contribution, we propose a novel opportunistic ambient backscatter
communication (ABC) framework for radio frequency (RF)-powered cognitive radio (CR) …

Ordered transmissions reduces the number of nodes that transmit in a wireless sensor
network (WSN) and yet achieves the same performance as the conventional unordered …

The wireless energy harvesting (EH) technique is regarded as a new way to provide an
energy supply for energy-constrained cognitive relay networks (CRNs). A novel wireless EH …

In this paper, cooperative spectrum sharing is considered between a primary user (PU) and
a secondary user (SU), where the off-the-grid secondary transmitter (ST) serves as a …

In normal computer networks, the data transmission between two sites go through the
shortest path between two corresponding vertices. However, in the setting of software …

In this paper, we study underlay device-to-device (D2D) communication systems
empowered by a reconfigurable intelligent surface (RIS) for cognitive cellular networks …

Integrating energy harvesting into cognitive radio networks can promisingly sustain the
operations of energy-limited terminals and improve the spectral efficiency. Traditionally …

In this article, we develop an analytical framework to study the impact of location-based relay
selection strategy on the reliability of cognitive relay networks. By utilizing the tool of …
