Towards Post-Quantum Blockchain: A Review on Blockchain Cryptography Resistant to Quantum Computing Attacks
(Institute of Electrical and Electronics Engineers, 2020-01-23)
[Abstract] Blockchain and other Distributed Ledger Technologies (DLTs) have evolved significantly in the last years and their use has been suggested for numerous applications due to their ability to provide transparency, ...
Creating the Internet of Augmented Things: An Open-Source Framework to Make IoT Devices and Augmented and Mixed Reality Systems Talk to Each Other
(MDPI AG, 2020-06-11)
[Abstract] Augmented Reality (AR) and Mixed Reality (MR) devices have evolved significantly in the last years, providing immersive AR/MR experiences that allow users to interact with virtual elements placed on the real-world. ...
Use Case Based Blended Teaching of IIoT Cybersecurity in the Industry 4.0 Era
(MDPI AG, 2020-08-13)
[Abstract]
Industry 4.0 and Industrial Internet of Things (IIoT) are paradigms that are driving current industrial revolution by connecting to the Internet industrial machinery, management tools or products so as to control ...
Numerical Model of a 28-GHz Frequency Diverse Array Antenna
(MDPI AG, 2020-08-22)
[Abstract] In this work we make use of the frequency diverse array (FDA) concept, whose design is based upon a frequency increment across the antenna elements to generate a beam steering that is a function of angle, time ...
FDD Channel Estimation Via Covariance Estimation in Wideband Massive MIMO Systems
(M D P I AG, 2020-02-10)
[Abstract] A method for channel estimation in wideband massive Multiple-Input Multiple-Output systems using hybrid digital analog architectures is developed. The proposed method is useful for Frequency-Division Duplex at ...
Decentralized P2P Broker for M2M and IoT Applications
(MDPI AG, 2020-08-20)
[Abstract]
The recent increase in the number of connected IoT devices, as well as the heterogeneity of the environments where they are deployed, has derived into the growth of the complexity of Machine-to-Machine (M2M) ...
Building Decentralized Fog Computing-Based Smart Parking Systems: From Deterministic Propagation Modeling to Practical Deployment
(Institute of Electrical and Electronics Engineers, 2020-06-25)
[Abstract] The traditional process of finding a vacant parking slot is often inefficient: it increases driving time, traffic congestion, fuel consumption and exhaust emissions. To address such problems, smart parking systems ...
Experimental Evaluation of Flexible Duplexing in Multi-Tier MIMO Networks
(SpringerOpen, 2020-09-24)
[Abstract]
In this paper, we present an experimental evaluation of the performance benefits provided by flexible duplexing, an access technique that allows uplink and downlink cells to coexist within the same time-frequency ...
Collaborative Augmented Digital Twin: A Novel Open-Source Augmented Reality Solution for Training and Maintenance Processes in the Shipyard of the Future
(MDPI, 2021)
[Abstract] Large companies use a lot of resources on workshop operator training and industrial machinery maintenance since the lack of this practice or its poor implementation increases the cost and risks of operating and ...
Design, Implementation and Validation of a Bluetooth 5 Real-Time Monitoring System for Large Indoor Environments
(MDPI, 2021)
[Abstract] The progress of LPWAN technologies in recent years has increased their use in various types of environments as well as increased the applications in which they are used. However, due to the duty cycle limitations ...
