Gergely Záruba's Main Research Areas and Projects:

Next Generation Wireless Networks

Work is focused on a concept we call Intelligent User Shadows for Next Generation Wireless Services (INGenioUS). The aim of INGenioUS is to seamlessly integrate all network access technologies into a single - uniform perception wireless access system to the user. To do this an agent is introduced into the wired network communicating with the user's terminal and all corresponding hosts. There are many novel aspects to this work, e.g., the introduction of software IP mobility and soft vertical handoffs among others. A technical report can be found here.

   
Wireless Localization Work 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 Connect project 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.
