A cognition scheme, whereby nodes are enabled with the full-duplex technology at the PHY
layer in conjunction with packet fragmentation at the MAC layer, is proposed to increase the …

In RF-powered full-duplex cognitive radio networks (FD CRNs), with the help of FD
technique and energy harvesting capability, secondary users (SUs) can conduct spectrum …

To prolong the lifespan of low-power cognitive sensors, we consider a backscatter-assisted
wireless-powered cognitive radio network (WPCRN) in which the sensors must harvest …

To serve massive connections in heterogeneous networks with respect to higher energy
efficiency, we focus on new paradigm in order to achieve multiple access and performance …

In the dynamic spectrum access (DSA) paradigm for cognitive radio networks (CRNs), one of
the commonly used Medium Access Control (MAC) schemes is designed on basis of the …

In order to overcome the problem that the traditional linear energy harvesting (EH) model is
not practical, this paper presents a practical nonlinear EH model, which considers the …

This paper develops and evaluates an accumulate-then-transmit framework for multiuser
scheduling in a full-duplex (FD) wireless-powered Internet-of-Things (IoT) system, consisting …

Cognitive radio (CR) and full-duplex (FD) have received extensive attention and research
due to their high spectrum efficiency, which can effectively solve the problem of low …

To enhance the spectrum utilization efficiency, cognitive radio and full duplex techniques are
considered as the two main effective methods. For the two-way communication underlay full …
