This paper considers a cooperative cognitive radio network with two primary users (PUs),
and two secondary users (SUs) that enables two-way communications of primary, and …

This paper investigates the physical-layer security (PLS) of a single-input-multiple-output
(SIMO) underlay cognitive radio network (CRN) over cascaded-fading channels. A …

The comprehensive performance of cognitive broadcasting networks employing Fountain
codes (FC) and maximal ratio transmission (MRT) is investigated in the present paper. More …

In this paper, physical-layer security (PLS) of an underlay cognitive radio network (CRN)
operating over cascaded Rayleigh fading channels is examined. In this scenario, a …

Physical-layer security (PLS) for an underlay cognitive radio network (CRN)-based
simultaneous wireless information and power transfer (SWIPT) over cascaded κ-µ fading …

This paper selects an unlicensed relay among available self‐powered relays to not only
remain but also secure information transmission from an unlicensed source to an unlicensed …

In this paper, an effective relay node (RN) selection scheme based on optimal power
splitting ratio (PSR) in dual hop decode and forward (DF) cooperative relay network (CRN) …

This paper investigates a reconfigurable intelligent surface (RIS)-aided underlay cognitive
radio (CR) multiple-input multiple-output (MIMO) wiretap channel where the secondary …

The fifth-generation (5G) communications and beyond are expected to serve a huge number
of devices and services. However, due to the fixed spectrum allocation policies, the need for …

In the field of meteorology, temperature forecasting is a significant task as it has been a key
factor in industrial, agricultural, renewable energy, and other sectors. High accuracy in …
