This paper focuses on the problem of sensing throughput optimization in a fading multiple
access cognitive radio (CR) network, where the secondary user (SU) transmitters participate …

This paper investigates the secrecy communication in an underlay cognitive radio (CR)
networks with one primary user (PU) as well as multiple PUs, where the radio frequency …

We consider a sampled-data control system where a wireless sensor transmits its
measurements to a controller over a communication channel. We assume that the sensor …

In this paper, we study the throughput optimization problem in energy harvesting based
cognitive Internet of Things (IoT), under cooperative spectrum sensing mode. Considering …

We present radio-frequency (RF) information harvesting, a chan-nel sensing technique that
takes advantage of the energy in the wireless medium to detect channel activity at …

Primary channel mean period plays an important role in improving the performance of
Dynamic Spectrum Access (DSA), because many algorithms to improve the performance of …

We consider a cognitive radio network where a secondary user (SU) tries to opportunistically
access the channel time unused by the primary users (PUs) to transmit real-time status …

We consider a wireless network comprising two types of nodes: Type I node and Type II
node. The Type I node has unlimited energy supply and the Type II node is powered by …
