Biography

I am from Bangalore, INDIA. I am pursuing my doctorate under the guidance of Prof. Eitan ALTMAN (INRIA) and Prof. Merouane DEBBAH (SUPELEC). I have a Masters from Indian Institute of Science (IISc), Bangalore. In the past, I had been involved in research and development activities in the areas of GPS, Integrated navigation, Voice-band Modems, CDMA, WLAN and WiMAX at ACCORD, ITTIAM and BECEEM. My current research interests span optimization, game theory, wireless networks, communication theory and signal processing. I live near the beautiful fort-town of Avignon in south of France and work from LIA, University of Avignon.

Research activities

I am working on aspects related to Optimization of small cell networks. The goal is to develop mathematical models and efficient algorithms for self-organizing small cell networks. The work would consider aspects of capacity, coverage, fairness, mobility, etc., in the backdrop of broadband wireless services based on CDMA, WiMAX or LTE technologies. Some of the problems addressed in the thesis are: 1) Cell dimensioning with static and mobile users using fluid limits and tools from spatial queueing theory. 2) Assigning base station locations to satisfy various fairness criterion under large population limits. 3) Asymptotic analysis of precoded small cell networks using random matrix theory. 4) Fairness and resource allocation in wireless networks. 5) Decentralized power allocation algorithms in small cell networks. 6) Energy conserving policies in Small Cell Networks 7) Handover Design and Management.
