On the contrary of low speed and high delay acoustic systems, underwater optical wireless
communication (UOWC) can deliver a high speed and low latency service at the expense of …

This paper investigates cooperative spectrum sensing in multi-channel cognitive radio
networks (CRNs) with energy harvesting. Our goal is two-fold: first, to determine the optimal …

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 …

Green energy powered cognitive radio is proposed as a promising method to improve the
energy efficiency (EE) and spectrum efficiency (SE). We consider the green power farms that …

In a cognitive radio (CR) sensor network, more than one node may sense the same channel
simultaneously. If the channel is available, those nodes may start to transmit data in this …

Cooperative spectrum sensing is a key technology for cognitive radio networks (CRNs)
where it can be used to identify idle spectrum holes. In a CRN, secondary users periodically …

With the recent developments in energy harvesting (EH) technologies, mobile devices are
able to support the wireless multimedia services by harvesting energy from various external …

The need to improve the utilization efficiency of the limited radio resources in the face of the
increasing number of radio network services, coupled with the growing interest in making …

Different priorities of users' access are defined in cognitive radio networks (CRNs) in order to
differentiate the spectrum usage: primary user (PU) preferentially occupies the band …
