Performance Analysis of Uplink Cellular IoT Using Different Deployments of Data Aggregators
Ghaith Hattab, Danijela Cabric
Data aggregation is an effective solution to enable cellular support of Internet-of-things (IoT) communications. Indeed, it helps alleviate channel congestion, reduce the communica…
Energy-Efficient Massive IoT Shared Spectrum Access over UAV-enabled Cellular Networks
Ghaith Hattab, Danijela Cabric
Data aggregation has become an emerging paradigm to support massive Internet-of-things (IoT), a new and critical use case for fifth-generation new radio (5G-NR). Indeed, data aggre…
Coexistence of 5G mmWave Users with Incumbent Fixed Stations over 70 and 80 GHz
Ghaith Hattab, Eugene Visotsky, Mark Cudak +1
Millimeter wave spectrum access over the 70GHz and 80GHz is central to unlocking gigabit connectivity and meeting the explosive growth of mobile traffic. A pressing question, howev…
Multiband Spectrum Sensing: Challenges and Limitations
Ghaith Hattab, Mohamed Ibnkahla
Multiband spectrum access presents the next generation of cognitive radio networks (CRNs), where multiple bands are sensed and accessed to enhance the network's throughput, improve…
Enhanced Pilot-Based Spectrum Sensing Algorithm
Ghaith Hattab, Mohamed Ibnkahla
In this paper, we develop an enhanced pilot-based spectrum sensing algorithm for cognitive radio. Unlike conventional pilot-based detectors which merely detect the presence of pilo…
Multiband Spectrum Access: Great Promises for Future Cognitive Radio Networks
Ghaith Hattab, Mohammed Ibnkahla
Cognitive radio has been widely considered as one of the prominent solutions to tackle the spectrum scarcity. While the majority of existing research has focused on single-band cog…
