Cooperative jamming is deemed as a promising physical layer-based approach to secure
wireless transmissions in the presence of eavesdroppers. In this paper, we investigate …

We study physical layer security in two-cell wireless networks in which a base station (Alice)
intends to send a confidential message to a legitimate user (Bob) with the help of a …

In this paper, the impacts of unreliable backhaul links on the secrecy performance of
cooperative single carrier heterogeneous networks in the presence of eavesdroppers are …

In this paper, we consider a multiuser downlink wiretap network consisting of one base
station (BS) equipped with AA antennas, NB single-antenna legitimate users, and NE single …

This paper investigates cooperative security in wireless networks, where a source (Alice)
intends to transmit a confidential message to a legitimate destination (Bob), with the help of …

The heterogeneous cellular network (HCN) is a promising approach to the deployment of 5G
cellular networks. This paper comprehensively studies physical layer security in a multitier …

This paper investigates the physical-layer security issue of an amplify-and-forward (AF) relay
network. We propose a joint cooperative beamforming (CB) and cooperative jamming (CJ) …

In this paper, we pioneer the study of physical-layer security in heterogeneous networks
(HetNets). We investigate secure communications in a two-tier downlink HetNet, which …

This paper proposes a new location-based multicasting technique, for dual phase amplify-
and-forward (AF) large networks, aiming to improve the security in the presence of non …

In this paper, we investigate the secrecy performance of multiuser dual-hop relay networks
where a base station (BS) communicates with multiple legitimate users through the …
