Cooperative Jamming for Wireless Physical Layer Security
Lun Dong, Zhu Han, Athina P. Petropulu +1
Cooperative jamming is an approach that has been recently proposed for improving physical layer based security for wireless networks in the presence of an eavesdropper. While the s…
Secure Wireless Communications via Cooperation
Lun Dong, Zhu Han, Athina P. Petropulu +1
The feasibility of physical-layer-based security approaches for wireless communications in the presence of one or more eavesdroppers is hampered by channel conditions. In this pape…
Performance Analysis of a Cross-layer Collaborative Beamforming Approach in the Presence of Channel and Phase Errors
Lun Dong, Athina P. Petropulu, H. Vincent Poor
Collaborative beamforming enables nodes in a wireless network to transmit a common message over long distances in an energy efficient fashion. However, the process of making availa…
Cooperative Beamforming for Wireless Ad Hoc Networks
Lun Dong, Athina P. Petropulu, H. Vincent Poor
Via collaborative beamforming, nodes in a wireless network are able to transmit a common message over long distances in an energy efficient fashion. However, the process of making…
A High-Throughput Cross-Layer Scheme for Distributed Wireless Ad Hoc Networks
Athina P. Petropulu, Lun Dong, H. Vincent Poor
In wireless ad hoc networks, distributed nodes can collaboratively form an antenna array for long-distance communications to achieve high energy efficiency. In recent work, Ochiai,…
