In this work, a cognitive relay network (CRN) with interference constraint from the primary
user (PU) with a mobile end user is studied. The proposed system model employs a half …

In this paper, a dual-hop underlay cognitive relay network (CRN) with a best-relay selection
(BRS) scheme under spectrum-sharing constraints from the primary user (PU) is …

This papers investigates security-reliability trade-off for multi-hop secure communication
networks using Fountain codes (FCs) and reconfigurable intelligent surface (RIS). In the …

In wireless networks, there are many channel impairments including shadowing, path loss,
and fading. Due to the shadowing, path loss, and fading, the direct transmission between the …
