IoT Consortium

Actively participating in the reference architecture of Fog Networking in Open Fog Consortium. [OpenFog Consortium members at Princeton]

Spectrum Policy Contributions

With colleagues Paul Garnett, Paul Mitchell, and Anoop Gupta in the Technology & Policy Group at Microsoft, we formulated and submitted a petition to the FCC on spectrum access in the new 3.5 GHz band, influencing the FCC to authorize dynamic spectrum access (DSA) in that band and considering other bands for the same DSA policies.

Deployments & Prototypes

Worked on the development of a cloudlet-based wireless video surveillance using intelligent camera sensors at Microsoft Research and University College London

Selected Standards Contributions

Led standardization of proposed novel dynamic spectrum management (DSM) algorithms for copper-access networks in ATIS COAST-NAI committee in USA and NICC committee in UK. The proposed algorithms are now included in “ATIS DSM technical report 2” and “NICC report for DSM methods on the UK access networks.”
