Unleashing the Power of Participatory IoT with Blockchains for Increased Safety and Situation Awareness of Smart Cities
Bechir Hamdaoui, Mohamed Alkalbani, Taieb Znati +1
IoT emerges as an unprecedented paradigm with great potential for changing how people interact, think and live. It is making existing Internet services feasible in ways that were p…
TrustSAS: A Trustworthy Spectrum Access System for the 3.5 GHz CBRS Band
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
As part of its ongoing efforts to meet the increased spectrum demand, the Federal Communications Commission (FCC) has recently opened up 150 MHz in the 3.5 GHz band for shared wire…
Location Privacy in Cognitive Radios with Multi-Server Private Information Retrieval
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
Spectrum database-based cognitive radio networks (CRNs) have become the de facto approach for enabling unlicensed secondary users (SUs) to identify spectrum vacancies in channels o…
Mixed RF/FSO Relaying Systems with Hardware Impairments
Elyes Balti, Mohsen Guizani, Bechir Hamdaoui +1
In this work, we provide a detailed analysis of a dual-hop fixed gain (FG) amplify-and-forward relaying system, consisting of a hybrid radio frequency (RF) and free-space optical (…
Aggregate Hardware Impairments Over Mixed RF/FSO Relaying Systems With Outdated CSI
Elyes Balti, Mohsen Guizani, Bechir Hamdaoui +1
In this paper, we propose a dual-hop RF (Radio-Frequency)/FSO (Free-Space Optical) system with multiple relays employing the Decode-and-Forward (DF) and Amplify-and-Forward (AF) wi…
Hybrid Rayleigh and Double-Weibull over Impaired RF/FSO System with Outdated CSI
Elyes Balti, Mohsen Guizani, Bechir Hamdaoui
In this work, we present a global framework of a dual-hop RF/FSO system with multiple relays operating at the mode of amplify-and-forward (AF) with fixed gain. Partial relay select…
