My research interests are in Computer Networks. My advisor is Dr. Rudra Dutta. Following are various projects that I have worked on.

Reliable Routing in Ad Hoc Networks

Fall 2010 - Present
I designed a multipath routing protocol for wireless ad hoc networks called 'Petal Routing'. This technique involves restricted flooding to increase reliabily while keeping the number of transmissions limited. The algorithm has been designed in such a way that that metrics such as reliability and urgency can be fine-tuned to get the optimal performance. We also provide enhancement techniques to further reduce the number of transmissions. The protocol has been tested using OPNET simulations. We have also carried out comparative tests with an existing multipath protocol that uses network coding. I recently passed my Written Preliminary Exam on this topic. Details about the exam including the report and slides, can be found here. Currently I am working on building an analytical model for Petal Routing that would help predict the reliability of an end-to-end transmission.

Network Virtualization Security

Fall 2009 - Spring 2010
Our research group is part of the GENI project (Global Environment for Network Innovations), which is a collaborative project spanning several universities across the US. The goal of the project is to design a virtualized network testbed, that would enable researchers to get a virtualized network slice, in order to test out networking ideas. This in turn would help develop and test innovate networking ideas, which would hopefully lead to designing the next generation internet. Since the testbed consists of a virtualized framework, there are several security implications. Not only are two virtual machines (VMs) in the same physical hardware communication, but VMs in different physical hardware are connected by virtual links. I investigated the security issues in such a framework.
