Physical layer security (PLS) in wireless communication systems has attracted extensive
research attentions in recent years. Unlike cryptography-based methods applied in upper …

The concept of physical-layer network coding (PNC) was proposed in 2006 for application in
wireless networks. Since then it has developed into a subfield of network coding with wide …

Wireless backhaul has recently gained a significant amount of interest as a cost-effective
solution in comparison with conventional backhaul technologies with dedicated microwave …

The conventional two-way relaying (TWR) protocol requires that the transmitter (receiver) in
one direction must be the receiver (transmitter) in the other direction, a limitation precluding …

This paper proposes relay selection to increase the physical layer security in multiuser
cooperative relay networks with multiple amplify-and-forward relays, in the presence of …

Authentication is a key requirement for secure communications in modern wireless systems.
Compared with the conventional authentication at the upper layer using a cryptographic tool …

Heterogeneous cloud radio access networks (H-CRANs) are potential solutions for
improving both spectral and energy efficiencies by embedding cloud computing into …

Cooperative communication has the potential of providing better throughput and reliability to
wireless systems when compared with direct communication. To realise the potential gain, it …

The unmanned aerial vehicle (UAV) is a promising enabler of Internet of Things (IoT) owing
to its highly flexible features. Combined with wireless power transfer (WPT) techniques, a …

Known interference (KI) is commonly used in many scenarios, where the original
interference data is known to the receiver in advance. Unfortunately, due to the impacts of …
