Resource allocation and physical layer security in wireless communication systems
… performance in terms of users' transmission rate. Under this context, a low-complexity but highly performing user selection algorithm is presented for the flat-fading channel, when zero-forcing beamforming is employed at the BS and the aim is to maximize system's throughput. For the more …

Transceiver design for wireless energy harvesting cooperative networks
… optimization problem is designed to maximize the secrecy rate. We also consider the application of energy harvesting in the full-duplex relaying network with a self-energy recycling protocol. Finally, the energy harvesting is studied in the full-duplex cooperative cognitive radio network. The …

Resource allocation and secure communication design in simultaneous wireless information and power transfer systems
… a rank-one proof presents that the solution generated by the relaxed problem is optimal to the original problem. Second, a security issue about the SWIPT system is investigated in a cooperative network in the presence of potential eavesdroppers. The AF relay protocol and a PS receiver …

Wireless Physical Layer Security: Towards Practical Assumptions and Requirements
… layer security on impractical assumptions. The secrecy enhancements and analysis based on impractical assumptions cannot lead to any true guarantee of secrecy in practical networks. The current study of physical layer security was often based on the idealized assumption of perfect channel …

Improving Implantable Medical Device Security Through Cooperative Jamming
… concerns have arisen as researchers have demonstrated it is possible to hack these devices to obtain sensitive information or potentially harm the patient. This is particularly easy to do as most IMDs transmit their data in the clear to avoid allocating their limited resources to encrypting their …
