Optimal Beamforming for Physical Layer Security in MISO Wireless Networks
A wireless network of multiple transmitter-user pairs overheard by an eavesdropper, where the transmitters are equipped with multiple antennas while the users and eavesdropper are equipped with a single antenna, is considered. At different levels of wireless channel knowledge, the problem of interest is beamforming to optimize the users’ quality-of-service (QoS) in terms of their secrecy throug...
متن کاملPhysical Layer Security in Wireless Communication Networks
Physical layer (PHY) security has become an emerging area of research recently. Wireless networks use unguided medium as communication channels, so gathering wireless data transmission is easier when compared to traditional cable systems. With the rise of new security challenges, many different solutions have been offered and are being developed. However, maintaining security in wireless networ...
متن کاملCorrection: Distributed beamforming designs to improve physical layer security in wireless relay networks
Correction In our paper Distributed beamforming designs to improve physical layer security in wireless relay networks [1], several equations should be corrected as indicated below. In section 2.1 ‘Amplify-and-forward’ , the equation included in the paragraph above Equation (2) incorrectly read as follows: ti =wiρiri This equation should read correctly as follows: ti =wi*ρiri In section 2.2 ‘Dec...
متن کاملDistributed beamforming designs to improve physical layer security in wireless relay networks
This paper investigates security-oriented beamforming designs in a relay network composed of a source-destination pair, multiple relays, and a passive eavesdropper. Unlike most of the earlier works, we assume that only statistical information of the relay-eavesdropper channels is known to the relays. We propose beamforming solutions for amplify-and-forward (AF) and decode-and-forward (DF) relay...
متن کاملCross-Layer Cooperative Beamforming for Wireless Networks
Cooperative beamforming (CB) is a signal transmission technique that enables long-range communications in an energy efficient manner. CB relies on cooperation from a set of distributed network nodes, each carrying a single transmit antenna and acting as elements of a virtual antenna array. By appropriately weighting their transmissions, the cooperating nodes form one or more beams to cooperativ...
