I am a fifth year graduate student at the Wireless Information Networking Laboratory at Rutgers University. My research interests are broadly in wireless and mobile networking and the security & privacy challeneges arising out of emerging mobile wireless systems.

I am passionate about the use of technology in addressing real-world and social problems.

Before coming to WINLAB, I was an undergrad at IIT Madras. Prior to moving to New Jersey, I lived in Mauritius, Chennai, Nairobi (Kenya), Bangalore, Hyderabad, Mumbai, Lagos (Nigeria), Mirzapur and Kanpur.

My Research

ParkNet: Mobile Sensors and Vehicular Wireless Networking

The ParkNet project aims to gather and disseminate information about street parking spaces using a mobile sensor network. The system employs pre-existing sensors in automobiles to infer the status of parking spaces as vehicles drive past them. A parallel goal of ParkNet is to design and implement suitable mechanisms for vehicle-to-vehicle and vehicle-to-infrastructure communications for the aggregation and dissemination of real-time parking information.

Fingerprints in the Ether: Physical Layer Wireless Security

The wireless medium possesses specific features that make it useful for several security and privacy problems arising in wireless networks. The characteristics of wireless propagation can be cleverly exploited to address the very security problems that make wireless networks harder to secure than their wired counterparts. The Fingerprints project explores these charateristics from the point of view of user authentication and data confidentiality. We show how unconditionally secure cryptographic keys can be extracted from the medium.

Chameleon: Adaptive Wireless Networks

The Chameleon project aims to study the efficiency and stability of cooperation betweem adaptive wireless devices that are capable of making their own decisions about which other devices to cooperate with. The framework developed by us addresses the question as to under what conditions does cooperation emerge as a stable and mutually beneficial outcome. We find that the quality of users links and their power budgets plays an important role in determining whether a group of users will be able to cooperate in a stable manner. Our work provides insights about when systems that depend upon user cooperation are likely to work and when cooperation is likely to fail.

Mobility Emulation on a the ORBIT Wireless Testbed

This project aimed to study whether mobile wireless devices can be effectivley emulated on a stationary wireless testbed for experimental research. We propse and evaluate a emulation methods that involves spatial switching between nodes in WINLAB's in-house indoor wireless testbed grid, ORBIT. We compared the effect of switching between spatially separated nodes in ORBIT with a moving robot carrying a wireless node.
