My Calendar

I
am currently a PhD candidate in the Department
of Computer Science at the University
of Illinois, Urbana Champaign.
I obtained my Masters degree at the University of Illinois,
Urbana-Champaign in Computer Science in Fall 2006. I was a Masters
student at the
Department of
Computer Science of
University of Virginia from Fall 2003-Fall 2005 and moved to
UIUC in Fall 2005.
I did my undergraduate from Indian
Institute of Technology - Madras
in Computer Science
and
Engineering.
Research
My main areas of research are Wireless Sensor
Networks, Wireless Networks, and Distributed Systems.
I work
with Prof.
Tarek
Abdelzaher. The current projects that I am working on are:
1.
Smart Attire
Smart attire is the next
generation of
clothing that will embed sensing and computing power in the clothing of
people to improve the lifestyle of our society. We envision that such
clothing will provide the user with various services, which
we
classify into four different categories:
1.
Elderly individual's health care
2. Safety
of people
3.
Personal and medical
4.
Entertainment
Towards this vision, we have
developed a
working prototype of a smart jacket, with sensing devices (MicaZ motes)
embedded in it, that records the daily activities of the person using
it in the form of accelerometer data, and GPS data. These data
collected are uploaded to a PC through a mote attached to it,
opportunistically. Such data are then interpreted to identify activity
and location information of the user. We are currently looking at
mining for "interesting" patterns in long term data, that we are
collecting as part of our ongoing research. More information about this
project can be found by following this link.
2. PoolView: Privacy in Cyber Physical Systems
3.
Seda:
Improving Throughput of Wireless Sensor Networks
Wireless sensor networks have
suffered from
low throughput caused by the high error rates (due to the low-end
radios) and small sized packets (TinyOS, the default operating system
for sensor networks, uses a 29 byte payload with a 16 byte header). We
developed Seda, a streaming datalink layer that improves the throughput
of sensor networks by decoupling the unit of communication (frame) from
the unit of error recovery. Seda introduces the unit of error recovery
as a block, which is significantly smaller than a frame to reduce the
overhead of error recovery, which is the primary cause for decreased
throughput. Seda is currently implemented in TinyOS and is available at
the following
page.
4. AlarmNet: Assisted-Living And
Residential Monitoring Network
AlarmNet is a project that I
am collaborating
on with the Department of Computer Science, University of Virginia.
This project aims to develop an architecture for intelligent health
care using wireless sensor networks. It is targeted at assisted-living
facilities and nursing homes and aims to improve the lives of elderly
individuals by making them more independent. Sensing and computing
devices are unobtrusively deployed in health care facilities, which
continously monitor the individuals' health and generate reports to the
authorized care providers. Currently, we have a system deployed that
mimics a typical health care facility. This system has several
components, such as the bed
network, motion
sensors, body network, human interfaces, and so on. More
information on this project can be obtained by visiting the following
webpage.
