Gergely Záruba's Main Research Areas and Projects:

Wireless Localization Work (supported by the U.S. Department of Justice) is focused on localization using received signal strength indication in wireless networks both infrastructure based and infrastructure less (ad hoc). Monte Carlo sampling based techniques and their variants are used to obtain location estimates from as little as one access point with high precision. Accelerometers as secondary sensors are also investigated where calibration and gravity detection are important issues. For publications please refer to the "Publications" section.

Technologies for People with Disabilities

In the context of the Teleherence project (NIH funded), a web-phone system is being developped that can help care givers of people with mental disabilities better manage their case loads.

In the context of the Connect project (Texas Health and human Services Comission funded) hosted by the Assist Laboratory, personal portable devices are developed to aid people with disabilities providing timely communications with their care providers and loved ones. Additionally, sensory devices are developed to relay environmental and personal reading possibly to alert for any exceptional circumstances.

Another project is focused on extending power wheelchairs with features of self navigation using localization techniques and real time sensory readings (and networks).

Sensor Networks Lifetime bounds of sensor networks are the focus of this work. A mathematical and simulation model is developed to create a comparative framework for obtaining maximum life of sensor network. This framework can be used to evaluate routing, scheduling and fusion algorithms.


Side tracks:

Network Traffic Investigation on how Internet traffic characteristics (especially self similarity of burst switched traffic) are changed by different optical access technologies.
TCP Congestion Control Investigation on how existing flow control mechanism may be used for more sophisticated and backwards compatible congestion control in TCP.
Job Scheduling in Grids Investigation and modeling (both analytical and simulation) of scheduling algorithms in grids, with emphasis on pricing and job bid based management.
