Secure User Association in Two-Tier Heterogeneous Cellular Networks With In-Band Interference
IEEE Access, 2018 In this paper, we address the issue of security-concerned user association in two-tier heterogeneous cellular networks with in-band interference. Different from the maximum secrecy capacity association (max-SC), which studied multi-tier heterogeneous ...

Enhancing wireless security via optimal cooperative jamming [PDF]
, 2012 In this work, we analyze the secrecy rate in a cooperative network, where a source node is assisted by relay nodes via cooperative jamming for delivering a secret message to the destination in the presence of an eavesdropper node.

Secure Transmission for Relay Wiretap Channels in the Presence of Spatially Random Eavesdroppers [PDF]
, 2015 We propose a secure transmission scheme for a relay wiretap channel, where a source communicates with a destination via a decode-and-forward relay in the presence of spatially random-distributed eavesdroppers.

Security–reliability tradeoff analysis of untrusted energy harvesting relay networks
International Journal of Distributed Sensor Networks, 2018 We investigate secure communications in untrusted energy harvesting relay networks, where the amplify-and-forward relay is an energy constrained node powered by the received radio frequency signals, and try to unauthorizedly decode the confidential ...

Impact of Heterogeneity and Secrecy on theCapacity of Wireless Sensor Networks
Sensors, 2015 This paper investigates the achievable secrecy throughput of an inhomogeneous wireless sensor network. We consider the impact of topology heterogeneity and the secrecy constraint on the throughput. For the topology heterogeneity, by virtue of percolation
