Title: Enabling Technologies for Internet of Things in 6G Networks

Affiliation: Department of Electrical & Computer Engineering Lakehead University, Barrie, ON, Canada 
Date and Time of Talk: Date:20th December 2023 Time: 14:45PM – 15:30PM


Future wireless networks (beyond fifth generation (5G)/sixth generation (6G) networks) are envisioned to connect satellite, aerial, terrestrial, and sea networks to provide connectivity everywhere and all the time. The objective is to provide connectivity to a large number of devices (known as massive connectivity), to support substantial traffic demands, and expand coverage. In addition, United Nations (UN) Sustainable Development Goals (SDGs) also call for 6G’s contribution. However, the success of SAGSI networks is constrained by several challenges, including resource optimization, when the users are resource-constrained and have diverse requirements and applications.

In this talk, I will start with a brief overview of the requirements and challenges in 6G networks. I will discuss the enabling technologies in 6G research. As examples, I will share my recent research on resource management schemes for massive connectivity in future terrestrial networks, aerial networks, and self-sustainable networks (SSNs) while considering different objectives and constraints, including network scalability, reliability, latency, efficiency (spectral usage and energy consumption), and complexity. The focus is to design novel algorithms and communication protocols for the Internet of things (IoT) networks that have both (i) enhanced network performance in terms of spectrum efficiency, coverage, and energy efficiency and (ii) satisfied a wide range of IoT devices’ requirements and constraints. I will then share future research challenges to develop efficient and low-complexity resource management schemes tackle the challenges of seamless connectivity of heterogeneous devices anytime and anywhere.
