On the delay/throughput-security tradeoff in wiretap TDMA networks with buffered nodes
(
IEEE
, 2019 , Article)
In this paper, we investigate the tradeoff between security and throughput and between security and queuing delay in wiretap time-division multiple access (TDMA) networks. We derive a simple relationship, characterized by ...
Integration of federated machine learning and blockchain for the provision of secure big data analytics for Internet of Things
(
Elsevier
, 2021 , Article)
Big data enables the optimization of complex supply chains through Machine Learning (ML)-based data analytics. However, data analytics comes with challenges such as the loss of control and privacy leading to increased risk ...
Secrecy Performance of Full-Duplex Jamming and Reception under I/Q Imbalance
(
IEEE
, 2021 , Article)
Investigating the physical layer security performance of full-duplex (FD) radio transceivers has been the subject of numerous research studies. However, self-interference cancellation that enables full exploitation of FD ...
Decentralized multiuser diversity with opportunistic packet transmission in MIMO wireless sensor networks
(
Elsevier
, 2013 , Article)
In this study, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ...
Joint learning and optimization for Federated Learning in NOMA-based networks
(
Elsevier
, 2023 , Article)
Over the past decade, the usage of machine learning (ML) techniques have increased substantially in different applications. Federated Learning (FL) refers to collaborative techniques that avoid the exchange of raw data ...
Distributed Inference in Resource-Constrained IoT for Real-Time Video Surveillance
(
IEEE
, 2023 , Article)
Advances in communication technologies and computational capabilities of Internet of Things (IoT) devices enable a range of complex applications that require ever increasing processing of sensors' data. An illustrative ...
I/Q imbalance in multiple beamforming {OFDM} transceivers: SINR analysis and digital baseband compensation
(
IEEE
, 2013 , Article)
In this paper, we start by investigating the impact of joint transmit-receive I/Q imbalance on the performance of direct-conversion beamforming OFDM transceivers. We derive a new analytical expression for the average ...
A regularization approach to MSE analysis of OFDM under phase noise
(
Elsevier
, 2018 , Article)
Orthogonal frequency division multiplexing (OFDM) is widely used in broadband wireless communications systems because of its high resilience to frequency-selective fading and its low implementation complexity. Phase noise ...
LCDnet: a lightweight crowd density estimation model for real-time video surveillance
(
Institute for Ionics
, 2023 , Article)
Automatic crowd counting using density estimation has gained significant attention in computer vision research. As a result, a large number of crowd counting and density estimation models using convolution neural networks ...
Exploiting Sparsity in Amplify-and-Forward Broadband Multiple Relay Selection
(
IEEE
, 2019 , Article)
Cooperative communication has attracted significant attention in the last decade due to its ability to increase the spatial diversity order with only single-antenna nodes. However, most of the techniques in the literature ...
