Welcome
I am a third year graduate student at the Department of Computer Science, UC Santa Barbara. I graduated with a B.Tech. in Computer Science and Engineering from the Indian Institute of Technology, Guwahati (IIT Guwahati) in May 2005, and I joined UCSB in Fall'05. I joined Moment Lab in Spring 2006.
My research interests lie in the field of Wireless Systems and Networking. I am interested in capacity improvement in multi-radio mesh networks and building wireless technologies for developing regions. I am especially interested in developing a software framework (MadMAC) for developing new multi-channel MAC protocols for Wireless Mesh networks on real systems.

Softwares
Here is a list of softwares I have developed over the years. One of these days I will release all the code. Until then feel free to write to me about any of these :
- FreeMAC: A Multi-channel MAC development framework using 802.11 hardware. (pdf)
- AODV-AS: An extension of AODV-ST routing protocol for wireless mesh networks. (WORKIT project)
- Kill-MAC: A network topology manager that allows the creation of arbitrary topology of nodes in a wired/wireless network. Ability to discard packets at the MAC layer before packets reach routing layer.
- MadMAC: A Reconfigurable Radio platform built on commodity 802.11 hardware. (paper) (presentation)
- MadFS: A Distributed Network File System built on User Mode Linux using FUSE . (Problem definition)
- TIDS: A Distributed WLAN Intrusion Detection System (BTech Project). (pdf)
- Fishbowl - A complete job search and application website built using Ruby-on-Rails. (Remnants..)
- Characterization of interference among orthogonal channels in UCSB 802.11 multi-radio MeshNet. (pdf) For a brief description on the above projects, please click here
