My area of interest is in wireless networks, sensor networks and p2p systems,
I am working with Prof. Badri.
These are some of the interesting projects I have worked while at Dataman,
in reverse chronological order:
TBF - Trajectory Based Forwarding is a new
routing protocol for sensor networks. The nodes in the network are assumed
to be location aware and all packets carry an encoded "trajectory"
that describes the path the packet must follow. Some obvious advantages are
decoupling the node id from the path, which is good for mobile networks. You
can read the paper here.
Andrew, Mike and me implemented this stuff on Mica motes running TinyOS.

Colored Range Searching survey I undertook for
the Database Systems course.
APS - Ad hoc Positioning System is a new
algorithm to enable Motes to know about their geographic location without
using GPS. You can read about the paper here.
I have implemented one of these protocols on the Motes. I also designed and
implemented a querying protocol which basically enables us to get/set the
protocol state on the Mote. There is also a nice TCL/TK
GUI that maps out the given sensor field in 2D and it is possible to
graphically query different properties of each node in the sensor field.

Slip Simulator - Motes can be emulated in software and its UART
can be accessed via a socket. We also have a working UDP/IP stack for the
Motes. While developing protocols, it is useful to have some sort of a
simulation framework. Slip simulator does this. Basically, it does FD
forwarding between a socket and TTY-pair, one side of which is attached to
the SLIP protocol using slattach.

Mote Gateway - This was my maiden project at Dataman!
Motes are really tiny wireless sensors, you can find more information about
motes are the Berkeley
website. This project enables multiple clients to query a Sensor network
over the internet.
