Resource Management for Massive Connectivity in Future Wireless Networks

Abstract: Future wireless networks (beyond 5G/sixth-generation (6G) networks) are envisioned to support 3D communication by integrating terrestrial and aerial networks. The objective is to provide connectivity to a large number of devices (known as massive connectivity), to support substantial traffic demands, and expand coverage. However, effective resource management in future wireless networks is a challenge because of massive resource-constrained devices, diverse quality-of-service (QoS) requirements, and a high density of heterogeneous devices. In this seminar, I will present my recent research progress which is focused on communication networking aspects of the Internet of Things (IoT), with emphasis on algorithm design, network architecture development, and system-level performance analysis. I will provide a brief discussion on my three most significant contributions which focuses on the design of novel algorithms and communication protocols for 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 the long-term goal of my research program which is to develop efficient and low complexity resource management schemes to tackle the challenges of seamless connectivity of heterogeneous devices anytime and anywhere. Finally, I will present my short-term objectives in the next five years which are to develop 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.
