Energy-efficient and secure wireless communications have recently earned tremendous
interests due to economic, environmental, and military concerns. This paper investigates the …

Herein, we consider an underlay cognitive radio network (CRN) where mobile secondary
user wishes to transmit a confidential information to the secondary destination in the …

In this paper, a novel wireless energy harvesting cooperative jammer (EH-CJ)-aided
transmission scheme, which can enhance the security for cooperative cognitive radio …

Physical layer security protects the transmitted data by trying to prevent the information from
reaching the adversary. Adding artificial noise (AN) to the transmitted data helps to achieve …

In this paper, a multiple-input single-output (MISO) simultaneous wireless information and
power transfer (SWIPT) system, including one base station (BS) equipped with multiple …

In this paper, we propose a destination-aided jamming scheme for secrecy simultaneous
wireless information and power transfer (SWIPT) in cognitive relay networks. In which, an …

In this work, a multiple-input single-output (MISO) simultaneous wireless information and
power transfer (SWIPT) system including one base station (BS) equipped with multiple …

A multiple-input single-output cognitive radio downlink network is studied with simultaneous
wireless information and power transfer. In this network, a secondary user coexists with …

The presence of correlated and imperfect channel state information (CSI) affects the secrecy
performance of cognitive radio networks (CRN). In this paper, we propose a physical layer …

In this paper, the secure communication of a cognitive radio network (CRN) over Nakagami-
m fading channel is investigated. An underlay protocol is used in the considered network …
