Physical Layer Security in Random NOMA-Enabled Heterogeneous Networks
IEEE Open Journal of the Communications SocietyThe performance of physical layer secrecy approach in non-orthogonal multiple access (NOMA)-enabled heterogeneous networks (HetNets) is analyzed in this paper. A K-tier multi-cell HetNet is considered, comprising NOMA adopted in all tiers.

A new achievable ergodic secrecy rate region for the fading multiple access wiretap channel [PDF]
2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009 We give a new achievable ergodic secrecy rate region for the two-user fading multiple access wiretap channel. Our scheme creates a vector channel between the two transmitters and the intended receiver that has full-rank and creates another vector channel between the two transmitters and the eavesdropper whose rank is 1.

On the ergodic secrecy capacity of MIMO wiretap channels with statistical CSI
, 2014 Wireless security has become an important issue for modern wireless networks. Due to the broadcast nature of wireless channels possibility of eavesdropping the transmission is provided for non-legitimate receivers.

Performance Study of Untrusted Relay Network Utilizing Cooperative Jammer [PDF]
AUT Journal of Electrical Engineering, 2016 —In this paper, the problem of secure transmission in two-hop amplify-and-forward (AF) systems with an untrusted relay is investigated. To prevent the untrusted relay from intercepting the source message and to achieve positive secrecy rate, the ...

Effects of CSI Knowledge on Secrecy of Threshold-Selection Decode-and-Forward Relaying
IEEE Access, 2017 This paper considers secrecy of a three node cooperative wireless system in the presence of a passive eavesdropper. The threshold-selection decode-and-forward relay is considered, which can decode the source message correctly only if a predefined signal ...

Human Resource Management, Volume 65, Issue 5, Page 1331-1351, September/October 2026.ABSTRACT HR faces a conundrum over how to organize hybrid working patterns given the pros and cons associated with conducting work across multiple domains. Many organizations are currently seeking to clarify and often increase the requirements for employee presence at employer premises, meaning studies are needed to better understand how HR should look
