Research Areas

I work broadly on mathematical modeling based system design and performance evaluation of stochastic networks, for upcoming 6G communications. The research is aligned with the upcoming 6G themes of ubiquitous connectivity and sustainability for future networks. A brief summary is provided below.

Vehicular networks: We are currently developing dimensioning and planning frameworks for LEO satellite constellations. At the very base, we design networks taking into account the underlying stochasticity arising due to the inherent physics (for e.g., the Doppler shift) and the network geometry, inferring engineering insights and evaluating the network performance. Research directions include statistical inference on the coverage, user outage, user association strategies, and routing. Mathematical tools used are inference theory, stochastic geometry, and probability theory. The use-cases include LEO satellites, UAVs, and HAPS.

Ambient powered distributed energy systems: We have studied the prospect of realizing distributed renewable energy (or ambient) powered base stations with the smart grid. The term "sustainability" is re-defined encapsulating economic scalability in addition to energy sustenance.

The use-cases of such ambient powered distributed energy systems is seen in energy aware networks, for e.g., smart grid networks, ambient powered wireless sensor networks, green data center networks, and residential networks.
