protocols, and management, control and interworking strategies for
telecommunication and computer networks;
- Applications to broadband, satellite,
wireless, mobile, and personal communications networking.
Summary
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 in the
future will integrate heterogeneous wireless 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 and personal multimedia
devices.
Current projects include:
(1) Collaborative situation-aware wireless sensor networks, (2) Provisioning
and management of IP-based multimedia mobility services over heterogeneous
broadband wireless networks, (3) Interworking between cooperative access
networks over IP backbone, (4) Enabling technologies for ultra-wideband
wireless communications and architectures, and (4) Protocols and management of
intelligent wireless networks. The issues addressed in these projects include
mainly: scheduling and resource management in networks to provide quality of
service guarantees, mitigating effects of heterogeneous networks on end-to-end
quality of service, and design of network architectures and protocols for
efficient mobility and handoff management. Previous research has resulted in
effective protocols for radio dispatch and group communications over mobile
satellite systems, reservation protocols for metropolitan area and satellite
networks, and seamless handoff rerouting method for ATM-based personal
communication networks and between CDMA cell clusters. Most projects involve
novel designs and performance evaluation by modeling and analysis using
analytical, numerical, and simulation methods. Where
feasible, experimental designs and implementations are also contemplated.
