Outage Constrained Secrecy Throughput Maximization for DF Relay Networks

IEEE Transactions on Communications, 2015
In this paper, we provide a comprehensive study of secrecy transmission in decode-and-forward (DF) relay networks subjected to slow fading. With only channel distribution information (CDI) of the wiretap channels, we aim at maximizing secrecy throughput of the two-hop transmission under a secrecy outage constraint through optimizing transmission region,

On the Reliability-Security Tradeoff and Secrecy Throughput in Cooperative ARQ

IEEE Communications Letters, 2014
This work has studied the physical layer security in cooperative automatic-repeat-request (CARQ), under the assumption of no instantaneous channel state information (CSI) at legitimate users. Different from present works, this paper not only derives closed form expressions for connection outage probability (COP) and secrecy outage probability (SOP) to ...

Exact Secrecy Throughput of MANETs with Guard Zone

2016 International Conference on Networking and Network Applications (NaNA), 2016
Different from previous works that mainly focus on deriving the scaling results for secrecy throughput of mobile ad hoc networks (MANETs), this paper studies the exact secrecy throughput of a cell-partitioned MANET with groupbased scheduling to eliminate interference from simultaneous transmissions.

Wireless Power Transfer and Cooperative Jamming for Secrecy Throughput Maximization

IEEE Wireless Communications Letters, 2016
This letter studies the secure communication between a wireless powered source node and a destination node in the presence of multiple eavesdroppers. We propose a hybrid base station (BS) scheme where the hybrid BS first transfers wireless power to the source and then performs cooperative jamming while the source transmits the information signal using ...
