The performance of secondary user in underlay cognitive networks is analyzed by
considering opportunistic selection of two-way full-duplex (FD)-based amplify-and-forward …

In relay-assisted cellular networks, when and how to cooperate for potential relay nodes is
an important issue, particularly from the energy-aware perspective. Moreover, addressing …

This paper addresses the power minimization problem subject to a target quality-of-service
(QoS) constraint of two-way relay systems with asymmetric traffic requirements using an …

This paper studies a novel channel access scheme for delay-sensitive multi-hop cognitive
radio sensor networks (CRSNs) with fixed decode-and-forward relaying. We first formulate a …

This paper addresses an optimal power adaptation (PA) problem of a two-time-slot bi-
directional relaying network with a half-duplex amplify-and-forward relay. Unlike the existing …
