I am a PhD student in electrical engineering at WINLAB, Rutgers University, NJ. My academic advisor is Prof. Wade Trappe. My research focusses on wireless spectrum sensing and cognitive radio.
A project that aims at enabling a richer range of experimental dynamic spectrum research supporting operation across 100Mhz - 6GHz in > 125MHz increments, hardware acceleration for real-world PHY waveforms at speeds of 100Mbps and higher, hardware virtualization capable of supporting multiple radios on the same platform. Developing wiserd - an open-source daemon type modularized and multithreaded C++ application that serves as the framework for distributed spectrum sensing system consisting of a number of deployed SDR sensors managed by a centralized controller.
Directional EW-aware Communications for On-the-move Networking project is exploring the development of a directional wireless networking architecture with OFDM waveform synchronized with GPS. A complete simulation of the entire architecture was built in Synopsys SPW.
As part of the EARS: Collaborative Research: Big Bandwidth: Finding Anomalous Needles in the Spectrum Haystack project, implemented and experimentally evaluated a game-theoretical spectrum scanning model to catch intruders/unauthorized users in a wide spectrum with a limited number of narrow-band scanners (USRPs), based on the probability of intruder presence in particular subbands.
