Colloquium: An Overview of Reconfigurable Intelligent Surfaces-Assisted Wireless Networks

April 24, 2024. Wednesday. 3PM. Room T23.

Speaker: Halil Yetgin (Middlesex University, London)

Abstract: As a promising technology for the upcoming 6G networks, reconfigurable intelligent surfaces (RIS) have garnered significant interest for their ability to boost network capacity, extend coverage, enhance efficiency and improve security, while minimising energy consumption and reducing hardware costs. This presentation aims to offer an overview of RIS, including their performance benefits, applications and industry efforts, and highlight future research opportunities. Finally, we will conclude with a scenario that showcases the use of an unmanned aerial vehicle (UAV) for gathering data from Internet of Things (IoT) devices, using RIS technology to improve data collection performance.

Bio: Dr Halil Yetgin obtained his doctorate in Wireless Communications from the Next Generation Wireless Research Group at the University of Southampton. He then became a research fellow in the Department of Communication Systems at the Jo┼żef Stefan Institute in Slovenia. He was also an assistant professor and gained valuable experience in teaching, research and administration. Dr Yetgin supervised both MSc and PhD students and contributed to EU-funded research projects. He participated in various IEEE conferences as a member of the TPC and is an associate editor of IEEE Access. His research mainly focuses on AI for wireless networks, including vehicular, UAV and IoT systems, as well as resource allocation and multi-objective optimisation.
