Relay selection is proposed in this paper as an efficient solution to secure information
transmission of secondary users against eavesdroppers in energy harvesting cognitive …

This paper proposes a jamming technique which employs a self-powered secondary
jammer to interfere a wire-tapper, who eavesdrops communications between a self-powered …

This paper investigate and enhances the bandwidth efficiency in the underlay cognitive
cooperative network with a reactive relay selection under interference and power …

The definition of the bandwidth efficiency (BE) of cognitive cooperative network (CCN) is the
ratio between a number of the licensed slot (s) or sub-channel (s) used by the unlicensed …

Energy harvesting has lately been of particular attention to researchers. In addition,
cognitive radio networks (CRNs) are recognized as an attainable measure for the problem of …

This paper exploits a self‐powered secondary relay to not only maintain but also secure
communications between a secondary source and a secondary destination in cognitive …

We investigate cognitive radio networks where the unlicensed sender operates in the
overlay mode to relay the information of the licensed transmitter as well as send its …

The spectrum sharing paradigm is a promising countermeasure to the spectrum under-
utilization problem. However, it causes both primary interference (inflicted by primary …

This paper analyzes secrecy outage probability (SOP) of underlay cognitive radio systems
(UCRSs) interfered by signals from primary networks, impaired by channel information …
