Location privacy preservation in secure crowdsourcing-based cooperative spectrum sensing
(
Springer International Publishing
, 2016 , Article)
Spectrum sensing is one of the most essential components of cognitive radio since it detects whether the spectrum is available or not. However, spectrum sensing accuracy is often degraded due to path loss, interference, ...
Achievable Rates of Buffer-Aided Full-Duplex Gaussian Relay Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We derive closed-form expressions for the achievable rates of a buffer-aided full-duplex (FD) multiple-input multiple-output Gaussian relay channel. The FD relay still suffers from residual self-interference (RSI) after ...
Optimal Group Formation in Dense Wi-Fi Direct Networks for Content Distribution
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Wi-Fi Direct enables direct communication between Wi-Fi devices by forming Peer to Peer (P2P) groups. In each P2P group, one device becomes the Group Owner (GO) and serves as an access point (AP) to connect the remaining ...
Securing Untrusted RF-EH Relay Networks Using Cooperative Jamming Signals
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We propose a new scheme to secure a wireless-powered untrusted cooperative-communication network, where a legitimate source node (Alice) transmits her information messages to a legitimate destination node (Bob) through the ...
Security-Enhanced SC-FDMA Transmissions Using Temporal Artificial-Noise and Secret Key Aided Schemes
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
We investigate the physical-layer security of uplink single-carrier frequency-division multiple-access (SC-FDMA) systems. Multiple users, Alices, send confidential messages to a common legitimate base-station, Bob, in the ...
Impact of the Wireless Network's PHY Security and Reliability on Demand-Side Management Cost in the Smart Grid
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We investigate the impact of the wireless network's physical layer (PHY) security and reliability on demand-side management operation in the smart grid. We assume that consumers communicate their energy demands with the ...
A Novel UAV-Aided Network Architecture Using Wi-Fi Direct
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
The use of unmanned aerial vehicles (UAVs) in future wireless networks is gaining attention due to their quick deployment without requiring the existing infrastructure. Earlier studies on UAV-aided communication consider ...
Analysis of In-band Full-Duplex OFDM Signals Affected by Phase Noise and I/Q Imbalance
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
The idea of the simultaneous transmission and reception of data using the same frequency is a potential candidate to be deployed in the next generation wireless communications standard 5G. The In-Band Full-Duplex (IBFD) ...
Coexistence of IEEE 802154g and WLAN
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
The aging electric grid was established hundred years ago when electricity needs were simple. The power plants were centralized and most homes had only small energy demands such as few lamps and radios. The grid role was ...
Machine learning screening of COVID-19 patients based on X-ray images for unbalanced classes
(
Hamad bin Khalifa University Press (HBKU Press)
, 2021 , Article)
Background: COVID-19 is a pandemic that had already infected more than forty-six million people and caused more than a million deaths by 1st of November 2020. The virus pandemic appears to have had a catastrophic effect ...
