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 multimedia services over heterogeneous wireless mobile broadband networks and wireless networking for sensors, vehicles, machines and personal multimedia devices.
Current projects include: (1) Exploiting cognition and adaptivity in advanced wireless network system designs, (2) Next generation broadband wireless access employing fibre-connected massively distributed antennas, (3) Wireless sensor networks for video surveillance, (4) Towards fourth generation wireless networks incorporating cognitive radios, (5) Security solutions for the future Canadian smart grid, (6) Context-aware services in next generation networks with applications to vehicular networking environments, and (7) Developing next generation intelligent vehicular networks and applications. The issues addressed in these projects 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. Where feasible, experimentations with practical implementations are also contemplated.
