About me
I am a graduate student at the Wireless Information Networking Laboratory at Rutgers University. My research interests are broadly in mobile systems, wireless networks and the security & privacy challeneges arising out of emerging mobile wireless systems. In 2010, my work on mobile sensing was featured in the MIT Technology Review. I spent the summer of 2006 as a systems engineering intern working on cognitive radio networking in the corporate R&D division of Qualcomm, San Diego and the summer of 2008 as an intern at the Chief Technology Office of InterDigial Inc. I received the prize for best research presentation at the Cyber Security Awareness Week 2008, at NYU. In 2009 I was a nominee for the Louis Bevier Rutgers fellowship. Before coming to WINLAB, I spent 4 wonderful years at IIT Madras.
I am passionate about the use of technology in addressing real-world and societal problems. Before coming to Jersey, I lived in Mauritius, Chennai, Nairobi (Kenya), Bangalore, Hyderabad, Mumbai, Lagos (Nigeria), Mirzapur and Kanpur. I blog (occasionally) at Alice, Bob & Eve.

Security & Privacy in Wireless NetworksThe repeated failure of wireless security protocols is due in large part to the fact that security designs in wireless systems have largely been adaptations of the ones designed for wired networks, and in effect, ignore the wireless aspect completely. My work explores how certain features particular to wireless links can be exploited to turn around the security problems in mobile wireless systems on their head. Fingerprints in the Ether (FitE) is a suite of algorithms and supporting protocols that practically exploit, to the benefit of security, some of the very features of wireless networks that make secure communication on them challenging. The FitE framework has been evaluated using 802.11a and the USRP/GNUradio software radio platform. |

Mobile SensingReal-time information on the availability of street-parking spaces in urban areas is likely to greatly lower traffic congestion, but is difficult to obtain without incurring huge costs. ParkNet is a experimental vehicular sensor network deployed on vehicles belonging to volunteering graduate students. The system uses sensor data to opportunistically gather and disseminate information about available street parking spaces using a city-wide mobile sensing network (say, using taxicabs as sensor vehicles). ParkNet vehicles employ a simlpe GPS receiver and a low cost ultrasonic rangefinder to accurately detect parked cars. The data is aggregated at a central server, which builds a real-time map of the city's parking availability. The cost/benefit ratio of the system scales much better than a stationary sensor network and can be immensely useful to mobile users looking for parking, city planners, and parking enforcement authorities. |

Automated Diagnosis of Interference Problems with Heterogenous RadiosWhile most studies on fault-diagnosis in wireless networks have focussed purely on 802.11 based WLANs, SpectrumMRI explores the nature and extent of interference problems between the multiple incompatible wireless standards that operate in the same 2.4 GHz unlicensed spectrum, to design a classifier for the automated diagnosis of interference-related problems. SpectrumMRI uses sensor nodes with multiple radio interfaces (802.11, Bluetooth, etc.) in conjunction with a software-radio based spectrum sensor to detect and classify interference problems. |

Cooperation vs. Competition in Adaptive Wireless NetworksThe 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 Chameleon framework addresses the following question: Under what conditions does cooperation between power constrained wireless devices 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.Coalitions in Cooperative Wireless Networks Suhas Mathur, Lalitha Sankar and Narayan B.

Mobility Emulation on the ORBIT Indoor Wireless TestbedThis 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.Mobility Emulation Through Spatial Switching on a Wireless Grid Kishore Ramachandran, Sanjit Kaul, Suhas Mathur, Marco Gruteser, and Ivan Seskar Demo at ACM MobiSys 2005.
