"My grandma asked me what I do. I said that I capture packets, reroute traffic, and secure networks, among other things. She thinks I am a cop." |
| My Research | I received my PhD in Computer Science from Brown University and my B.Tech in Computer Science and Engineering from the Indian Institute of Technology (IIT), Delhi. My research interests include the design and implementation of algorithms; IP and converged networking; wireless, mobility and location management; network management; security; and the World Wide Web. |

| Projects | My current research explores several issues in converged and wireless networking. As part of the ORBIT project (Overlays Providing Reliability for Better IP Telephony), we investigate how to provide reliability and availability for real-time traffic (e.g., IP telephony) over inherently unreliable IP networks. The issues include measurement of the current state of the network, and using the measurements for making informed control decisions rapidly. As part of the Wireless PALMS (Profiling, Assessment, Location Estimation, Monitoring and Security) project, we have developed a new adaptable architecture and techniques for indoor wireless location estimation and site assessments. Our prototype implementation, Palantir, is a sniffer-based single-board implementation that provides monitoring, security and location estimation. We have also analytically studied the limits of location estimation accuracy. Our Proton (Protection of Networks) architecture and prototype implementation provides methods to protect a network from malware and also ensures security policy compliance. |

| Publications | I have more than 40 papers in journals and technical conferences (IEEE, ACM, Usenix, etc.) in the areas of networking, network management, computing systems and computer science. I also have over 20 patents/patent applications (8 granted). Some of my recent publications include a paper on the LEASE location estimation architecture (IEEE Infocom 2004), an analysis of location estimation limits and a zero-profiling technique for location estimation in wireless LANs (both in IEEE Infocom 2005), a paper on IP telephony reliability and another on wireless security (both in IEEE ICC 2004). Other areas of publication include: prediction, prefetching and caching, mobile power conservation, network management and security, wireless, etc. For a complete list of publications and copies of papers, please contact me. |
