Keynote  Speaker 1 : Dr. Santi P. Maity - Reconfigurable Intelligent Surface in 6G Communications: Challenges, Opportunities and Applications

Dr. Santi P. Maity joined the faculty of Indian Institute of Engineering Science and Technology, Shibpur, India (IIEST Shibpurat) (formerly BEC(DU), BESU Shibpur) in the year 2000, where at present, he is a Professor (HAG) in Dept. of Information Technology. He  served as the Head of different of various academic units of the Institute, namely Dept. of Information Technology, Purabi Das School of Information Technology (PDSIT), School of VLSI (SVLSI) and School of Mechatronics and Robotics (SMR) and School of Advanced Materials, Green Energy and Sensor Systems (SAMGESS). He received his B.E. degree in Electronics and Communication Engineering from National Institute of Technology Durgapur and M.Tech. in Microwaves from the University of Burdwan, India in 1993 and 1997, respectively.  He received his Ph.D. degree in Engineering from IIEST Shibpur in 2008 and did Post-Doctoral work from January 2009 to July 2009 and February 2011 to July 2011 at the Laboratoire des Signaux et Systems (CNRS–Supelec–Universite Paris-Sud 11) in France. His research interests include Cognitive Radio Networks, MC-CDMA systems, Digital Image Watermarking and Secret Sharing, Compressed Sensing based Image Reconstruction and Disease Diagnosis, and Computer Aided Diagnosis (CAD) based Gradation on Diabetic Retinopathy. His current research areas also include the use of Reinforcement Learning (RL) in Spectrum Prediction, Reconfigurable Intelligent Surfaces (RIS) in D2D communication and optimal placement of charging stations in Electric Vehicle (EV) systems. He has published more than 325 research papers in International journals, International and National conference proceedings, and book chapters. He has guided 21 Ph. D theses so far and examined more than 70  Ph. D theses of various institutes that include foreign institutes, State universities, Central Universities, NITs, IITs and IIITs. He has delivered so far more than 80 invited, keynotes and tutorial talks in International and National conferences, seminars, workshops, symposiums and FDP program.

Abstract: Energy Efficiency (EE) and Spectrum Efficiency (SE) are two key performance metrics in the sixth generation (6G) wireless communication networks due to the ultra-massive connectivity requirements in future Internet of Things (IoT) scenarios such as smart cities, healthcare, automation in industries, environmental gas monitoring etc. Reconfigurable intelligent surface (RIS)-looks promisig to offer relaible and seamless wirleless link connection  to simultaneously achieve high EE and SE in various applications on challenging wireless environment. To address spectrum scarcity, cognitive Radio (CR) and to meet energy issues, RF energy harvesting (EH) have also been integrated in RIS- CR-IoT communications in recent times. This lecture will talk about scope, challenges and opportunities in RIS-aided SE and EE communications for some IoT applications.
