Research Projects

This project aims to address three fundamental problems for large-scale wireless networks: network lifetime, spectrum scarcity, and security. Enabling spectrum sharing in licensed spectrum can significantly impact social, economic, and policy-making aspects of future wireless networks. Physical layer security can play a crucial role in preventing security breaches and decoding messages. The project also explores the use of simultaneous wireless information and power transfer (SWIPT) technology as a promising energy harvesting scheme. SWIPT has potential applications in the Internet of Things (IoT) networks, factories, refineries, and farms. The project aims to develop and analyze SWIPT-enabled spectral efficient protocols for sustainable and ubiquitous large-scale wireless networks, analyze physical layer security aspects in SWIPT-enabled systems, investigate performance in various practical conditions, and apply soft-computing and convex optimization tools for resource allocation. The project will verify its theoretical and analytical findings with numerical and simulation studies. Physical layer security can be integrated into various types of wireless networks, and the project will demonstrate two spectrum sharing scenarios of a centralized network.
