IEEE International Black Sea Conference on Communications and Networking
6–9 June 2022 // Sofia, Bulgaria


Monday (June 6, 2022)

10.00-13.00 – Tutorial 1: “Blockchain as a Database, Communication Networks and WEB3.0”

Presented by  Dr. Abdullah Uz Tansel, City University of New York, USA

Contents: The tutorial covers the permissioned and permissionless blockchains as a database and their fundamentals, WEB3.0 and its communication requirements, trusted protocols in network communications, briefly cryptocurrencies, and connection of IoT devices. It focuses on adding trust to communication and P2P networks with blockchains. The topic is timely and relevant for communications and networks researchers and designers who are expected to develop an appreciation of blockchain innovation and its potential in their works.

Speaker’s Biography

Abdullah Uz Tansel received his BS in management, and his MS and PhD degrees in computer science from the Middle East Technical University, in Ankara Turkey. He has also received his MBA degree at the University of Southern California. After being a faculty member at the Middle East Technical University, Dr. Tansel joined Baruch College, the City University of New York (CUNY) where he is currently a professor of information systems and also a professor of computer science at The Graduate Center of CUNY. Professor Tansel’s research focus is on temporal databases and he has made significant contributions in this field. He also headed the editorial board that published the first book on temporal databases ‘Temporal Databases: Theory, Design, and Implementation’ (1993). Dr. Tansel has a patent on adding temporality to RDF. His research interests are Database Management Systems, Temporal Databases, Semantic Web, and Blockchain Databases. Dr. Tansel has published many articles in the conferences and journals of the ACM, IEEE and other associations. He is a frequent speaker on time in databases and blockchain as a database. He is also a member of the ACM and the IEEE Computer Society.

14:30-17:30 – Tutorial 2: “Antenna Optimization and Beamforming for 5G/6G Communications”

Presented by Dr. Zaharias D. Zaharis, Aristotle University of Thessaloniki, Greece and Dr. Pavlos Lazaridis, University of Huddersfield, UK.

Contents: Several evolutionary optimization methods will be presented in conjunction with the CST 3D simulator in order to efficiently optimize multiband handset and base station antennas for 5G/6G communications. Some of the optimizers that will be presented are: Particle Swarm Optimization (PSO), Invasive Weed Optimization (IWO), modified IWO, etc. Furthermore, beamforming techniques will be introduced because of their usefulness in mmWave communications. Some of the beamforming algorithms that will be presented are: Null Steering Beamforming (NSB), Minimum Variance Distortionless Response (MVDR), and neural network-based beamformers.
