Secure Communications in Millimeter Wave Ad Hoc Networks
Yongxu Zhu, Lifeng Wang, Kai-Kit Wong +1
Wireless networks with directional antennas, like millimeter wave (mmWave) networks, have enhanced security. For a large-scale mmWave ad hoc network in which eavesdroppers are rand…
Secrecy and Energy Efficiency in Massive MIMO Aided Heterogeneous C-RAN: A New Look at Interference
Lifeng Wang, Kai-Kit Wong, Maged Elkashlan +2
In this paper, we investigate the potential benefits of the massive multiple-input multiple-output (MIMO) enabled heterogeneous cloud radio access network (C-RAN) in terms of the s…
Wireless Power Transfer in Massive MIMO Aided HetNets with User Association
Yongxu Zhu, Lifeng Wang, Kai-Kit Wong +2
This paper explores the potential of wireless power transfer (WPT) in massive multiple input multiple output (MIMO) aided heterogeneous networks (HetNets), where massive MIMO is ap…
Artificial-Noise Aided Secure Transmission in Large Scale Spectrum Sharing Networks
Yansha Deng, Lifeng Wang, Syed Ali Raza Zaidi +2
We investigate beamforming and artificial noise generation at the secondary transmitters to establish secure transmission in large scale spectrum sharing networks,where multiple no…
Physical Layer Security in Three-Tier Wireless Sensor Networks: A Stochastic Geometry Approach
Yansha Deng, Lifeng Wang, Maged Elkashlan +2
This paper develops a tractable framework for exploiting the potential benefits of physical layer security in three-tier wireless sensor networks using stochastic geometry. In such…
