My research interests are in the area of telecommunications and computer communications networking. The scope of the research includes design, evaluation, and analysis of network architectures, protocols, and network management, control, and internetworking strategies for reliable, efficient, and cost effective communications. The convergence of wireless and broadband communications has led to the integration of heterogeneous wireless and wireline networking technologies, often into the same device, to enable ubiquitous multimedia communications among people and machines regardless of locations and mobility. The thrust of the research is to contribute to the development of this emerging global network, with current focuses on energy efficient service provisioning over 5G wireless mobile broadband networks and beyond. The issues addressed include mainly: scheduling and resource management in networks to provide quality of service guarantees, design of network architectures and protocols for high performance and energy-efficient broadband communications, development of protocols and mechanisms for security and privacy in wireless networks, and development of protocols and algorithms for application-specific wireless networking. Most projects involve novel designs and performance evaluation by modeling and analysis using analytical, numerical, and simulation methods. While optimization techniques are widely used in the research, increasing model-free machine-learning based approaches are contemplated to facilitate practical implementations.
