About me
I graduated from University of Illinois at Urbana-Champaign with my PhD in Computer Science in 2001.
I got my MS degree in Computer Science from Michigan State University (1997) and my BTech degree
in Computer Science and Engineering from IIT Delhi, India (1995).
Before joining OSU in 2003, I was a researcher at Bell Labs, New Jersey from 2001 to 2003.
During my graduate studies I did internships at Almaden Research Center, IBM, San Jose, and HRL Labs, Malibu.
I am an IEEE senior member since April 2010. I received the Lumley Research Award from the College of Engineering at OSU in 2009, and the NSF CAREER award in 2006.
During graduate studies I received the Mavis Memorial Scholarship (2000),
Ray Ozzie Fellowship (1999), and the Distinguished Academic Achievement Award (1997).
I am currently serving on the editorial boards of Transaction on
Wireless Communications (TWC) and Transactions on Mobile Computing (TMC).
I am currently serving as a TPC co-chair for IWQoS 2011, and I recently served as TPC co-chair for
BROADNETS 2010 and TPC chair for QShine 2009.
Research (Click here for a detailed research statement)
My research focuses on the design of wireless network architectures and protocols,
with current emphasis on sensor networks and cellular networks.
I am particularly interested in algorithmic solutions to foundational
issues in the design of network solutions, and experimental studies on real networks.
Many of the research problems that I have worked on are motivated by applications
from the domain of cyber-physical systems such as flood control, traffic control,
earthquake monitoring and the smart-grid.
In 2004, for the
DARPA/NEST sponsored ExScal
demonstration held at Avon Park, Florida,
my responsibilities included designing network layer solutions
for a network of 1000 Mica2/XSM based sensors (world's largest to date)
that was supported by a backbone wireless mesh network of 200 Linux based
Stargate nodes (also world's largest).
My recent research contributions are in the following two areas:
Perpetual Networking
Sensor networks are being deployed around the world to monitor a wide variety of phenomena
including earthquakes, volcanic activities, air pollution, and various weather related parameters.
In many of these application scenarios, renewable energy sources such as
solar or wind energy is readily available. Renewable energy can be leveraged to
provide continuous (or perpetual) data services. Due to the small amout of energy that can be typically harvested using
small form-factor recharging devices, dynamics of renewable energy, and difficulty in its precise estimation, providing
services without interruptions caused by battery
runouts is non-trivial. Most environment monitoring applications require data collection from all nodes at a
steady rate. How can our applications operate in presence of
such dynamics and yet collect high fidelity of data? Towards answering these questions, we have designed
solutions for fair and high throughput data collection in presence of such dynamics.
Some publications in this area to introduce you to this new area are as follows:
Designing and deploying wireless infrastructures of devices with short range has always
been expensive and difficult to manage. Recently WiFi deployment projects have been scaled
back in various cities. Although WiMAX and LTE are expected to increase the 3G bandwidth,
customers are still missing the broadband experience over cellular networks.
Is there a way to strategically and sparsely deploy WiFi access-points to provide good data quality
for mobile users anywhere in the road network?
Another example is -- large scale sensor network deployment for various applications.
Although we are beginning to see many small scale deployments for specific applications,
large scale deployments (e.g., city-wide) are prohibitevely expensive.
So the key question is --
What notions of network coverage can we achieve when the budget is limited?

Note for Prospective Students: I am looking for one or two highly motivated students to join
my group immediately with background and/or interest in mathematical techniques
and/or experimental skills.
Mathematical topics of particular relevance to my research include approximation
algorithms, combinatorics, graph theory, probability, optimization etc.
Experimental skills in TinyOS, 802.11, Linux kernel programming, and
mesh networks is also relevant.
