In this article, we investigate the performance of a piece-wise linear model of energy
harvesting-based multiuser overlay spectrum sharing system. Herein, an energy …

This paper mainly describes the transmission reliability and physical layer security of
multiantenna decode-and-forward relay networks over the-shadowed fading distribution. We …

In this paper, we investigate the performance of energy harvesting two-way relay systems in
the presence of transceiver hardware impairments (HIs). In order to improve the reliability of …

In this paper, the performance of a wireless system, which is beneficial from utilization of
multiple reconfigurable intelligent surfaces (RISs) and the direct link between the source …

In this paper, we investigate the physical layer security for a cognitive multiuser network
which is composed of multiple cognitive sources, a cognitive destination and an …

We investigate physical-layer security for a multiuser underlay cognitive system with
hardware impairments (HIs) and channel estimation errors (CEEs), which comprises …

In this paper, we propose a rateless codes-based communication protocol to provide
security for wireless systems. In the proposed protocol, a source uses the transmit antenna …

In this paper, we evaluate the secrecy performance of multi-hop cognitive wireless sensor
networks (WSNs). In the secondary network, a source transmits its data to a destination via …
