Artificial noise, energy harvesting, and overlay communications can assure design metrics of
modern wireless networks such as data security, energy efficiency, and spectrum utilization …

This paper investigates the secrecy outage performance of Multiple Input Multiple Output
(MIMO) secondary nodes for underlay Cognitive Radio Network (CRN) over α–μ fading …

Vehicular communication has been envisioned to support a myriad of essential fifth-
generation and beyond use-cases. However, the increasing proliferation of smart and …

Security in wireless networks is challenging. Security in cognitive radio networks (CRN) is
even more challenging. This is because a CRN consists of cognitive radios (CR) which have …

In this study, the authors consider a cooperative communication framework based on one‐
way and two‐way relays to provide secure communications for secondary users (SUs) within …

This paper studies the physical layer security in cognitive relay network (CRN) with multiple
antennas in the presence of multiple eavesdroppers. Under spectrum sharing scenario and …

The advent of the Internet of Things (IoT) has revolutionized connectivity by interconnecting
a vast array of devices, underscoring the critical need for robust data security, particularly at …

In this paper, we investigate the secrecy outage performance of decode-and-forward (DF)
buffer-aided multi-antenna underlay cognitive relay networks (CRNs) in the presence of an …

The growth of wireless devices affects the availability of limited frequencies or spectrum
bands as it has been known that spectrum bands are a natural resource that cannot be …

In this paper, we propose an exact closed-form expression of secrecy outage probability
(SOP) for underlay cognitive network with energy scavenging capable relay over Nakagami …
