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 ...

Secrecy Throughput of Wireless Interference Networks with Uncertain Channel State Information

open access: yes2017 IEEE Globecom Workshops (GC Wkshps), 2017
Considering a multi-user interference network with an eavesdropper, this paper investigates the problem of power allocation to optimize the worst secrecy throughput among the network links. Three scenarios for the access of channel state information are considered: perfect channel state information, partial channel state information with channels from ...
