Abdallah S. Ghazy
Bio:
Abdallah Ghazy received the B.Sc. degree in Electrical Engineering from Al-Azhar University, Cairo, Egypt, in 2007, the M.Sc. degree from the Egypt-Japan University of Science and Technology (E-JUST), Alexandria, Egypt, in 2016, and the Ph.D. degree in Electrical and Computer Engineering from McMaster University, ON, Canada, in 2021. From 2008 to 2017, he worked in the telecommunications industry with Sina Technology, Cairo, Egypt, where he contributed to the design, deployment, and operation of telecommunication systems and networks. Alongside his industrial experience, he served as a Teaching Assistant at both Al-Azhar University and McMaster University between 2012 and 2021, supporting courses and laboratory activities in communications, signal processing, and networking systems. Between 2021 and 2025, he was a Research Fellow with École de technologie supérieure (ÉTS), Montréal, Canada, where he conducted advanced research on Space and Defence technologies. Since December 2025, he has been a Research Associate with Calian Group Ltd., Ottawa, Canada, contributing to research and development activities in advanced Space and Defence technologies. His research has contributed to emerging communication paradigms spanning RF, optical, acoustic, underwater, and satellite communication systems, with an emphasis on heterogeneous networking, intelligent protocol design, signal processing, machine learning, and communication security. His work also explores AI-assisted optimization techniques for future resilient and adaptive communication <a href="http://infrastructures.

Abstract:
Underwater wireless sensor networks (UWSNs) have gained increasing attention for civil and defense applications, but underwater environments present major challenges such as dynamic channels, localization difficulties, high delays, limited bandwidth, energy constraints, interference, and strong noise. This work presents a comprehensive survey of UWSN protocols across the physical, MAC, and routing layers, including existing network stacks, underwater modems, and security threats, with emphasis on the Smart Adaptive Long- and Short-range Acoustic (SALSA) stack. The survey also discusses emerging technologies in machine learning and cybersecurity for intelligent, adaptive, and secure underwater communication systems, highlighting their potential in channel estimation, routing optimization, anomaly detection, intrusion prevention, and autonomous network management. Based on the identified research gaps, two main contributions are proposed. First, Developed-SALSA (D-SALSA) stack protocols are introduced to improve adaptability, energy efficiency, throughput, and communication reliability. Second, a heterogeneous underwater architecture combining acoustic and optical communication technologies is presented to support high-rate and large-scale data transmission. Finally, future research directions and open challenges related to AI-assisted networking, cross-layer optimization, and resilient cybersecurity frameworks are <a href="http://discussed.
