CONFERENCE PUBLICATIONS
SOFTWARE RELEASES
Wireless Control Protocol (WCP) and Wireless Control Protocol with Capacity
Estimation (WCPCap):
WCP and WCPCap have been implemented in Qualnet simulator while a Linux
implementation of WCP has been developed using Click Modular Router. Both
these implementations are available from ENL repository at
http://enl.usc.edu/software.html
Interference-Aware Fair Rate Control (IFRC):
IFRC has been implemented on Tmote Sky and has been tested on 40 nodes in
our testbed. IFRC is available from ENL repository at
http://enl.usc.edu/software.html and from sourceforge at
http://tinyos.cvs.sourceforge.net/tinyos/tinyos-1.x/contrib/usc-ifrc/. IFRC
has also been successfully used by others at SING (Stanford), ENL (USC), and
ANRG (USC).
Wireless Sensor Network for Structural Health Monitoring (Wisden):
Wisden was tested on 15 nodes indoor testbed as well as on a damaged
building and is available from ENL repository at
http://enl.usc.edu/software.html

RESEARCH PROJECTS
Congestion Control in Wireless Networks (WCP and WCPCap):
WCP and WCPCap are transport protocols designed for multi-hop wireless mesh
networks. WCP outperforms TCP, in terms of fairness, both in simulations
and real world experiments while WCPCap achieves max-min fairness in
simulations on our test topologies.
I was the project lead and was responsible for the design, implementation
(in simulation), and evaluation of the schemes.
(This work was published in MobiCom 2008.)
Interference Aware Fair-Rate Control (IFRC):
IFRC is a transport protocol for multi-hop wireless networks with
(tree-like) many-to-one traffic pattern that is typical of most wireless
sensor networks. IFRC's performance has been successfully verified on a 40
node testbed achieving within 20%-40% of the optimal fair rates on our test
topologies.
I was the project lead and was responsible for the complete design,
implementation, and evaluation of the protocol.
(This work was published in SIGCOMM 2006.)
Wireless Sensor Network for Structural Health Monitoring (Wisden):
Wisden is a wireless network based data-collection system for civil
structures. It supports acquisition of structure vibration data for up to
200Hz along 3-axes using reliable data delivery, data synchronization, and
data compression mechanisms. Wisden has been successfully deployed on a test
structure as well as on a real building (shaken using hydraulic shakers).
Experience gained from Wisden resulted in Tenet, a new architecture for
sensor networks.
I was responsible for the design and implementation of the data
synchronization protocol, a bus arbitration protocol, and modifying device
drivers to facilitate communication between motes (embedded devices) and
external sensor boards. In addition, I was also involved in its field
deployment on a damaged building.
(This work was published in SenSys 2004.)
Energy Profiling of Network Interfaces on Smart-phones:
The project involved energy profiling of network interfaces (Wi-Fi,
Bluetooth, GPRS, and GSM) on smart-phones and investigating schemes to
transparently switch interface to save energy.
This work was performed at Microsoft Research, India.
