Minimum Secrecy Throughput Maximization in Wireless Powered Secure Communications

IEEE Transactions on Vehicular Technology, 2018
This paper investigates a wireless powered secure communication network (WPSCN), in which the legitimate users have no constant energy supply and need to be wireless powered for information transmitting. The harvest-then-transmit protocol is adopted in the WPSCN, i.e., the energy access point (EAP) first transfers energy to legitimate users through ...

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.

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,

Secrecy Throughput Maximization for Full-Duplex Wireless Powered Communication Networks

ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019
In this paper, we investigate the secrecy throughput for a full-duplex wireless powered communication network. A multi-antenna base station (BS) transmits energy towards nodes all the time and each node harvests energy prior to its transmission time slot.

Secrecy Throughput Maximization for Massive MIMO Wireless Powered Communication Networks

2019 IEEE Global Communications Conference (GLOBECOM), 2019
In this paper, we study the secrecy throughput in a massive Multiple-Input-Multiple-Output (MIMO) full-duplex wireless powered communication network (WPCN). The network consists of a massive MIMO base station (BS) and two groups of single- antenna sensor nodes which harvest energy from the BS.

Exact secrecy throughput capacity study in mobile ad hoc networks

Ad Hoc Networks, 2018
Abstract The secrecy throughput capacity (STC) performance study of mobile ad hoc networks (MANETs) is critical for supporting their applications in security-sensitive scenarios. Despite much work on the scaling law results of MANET STC, the exact STC study of such networks remains an open problem.

Average Secrecy Throughput Analysis with Multiple Eavesdroppers in the Finite Blocklength

2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020
This paper studies the problem of secure communication from a transmitter to a receiver with the use of short packets under the existence of multiple eavesdroppers, who are overhearing the transmission. We assume that the eavesdroppers are mutually independent.
