Research Areas

A professorial career that involves never ending search for truth, should build strong research. I do work on performance analysis and resource allocation issues in communication networks. I wish to continue publishing on computer networking, network coding, Energy Efficient cooperative communication, and network optimization. We use mathematical methods from related scientific areas of graph theory, dynamic graphs, MDPs, decentralized distributed learning in multi agent systems, mechanism design to ensure targeted desirable emergence, queuing models and optimization. Applications like sensor network to secure intelligent infrastructure, modeling computational trust over an electronic social network, evolution of cooperation in ad hoc networks certainly draws my attention. Cognitive and cooperative Communication, network coding, optimization based stack design incorporating new technologies, self-deployment in mobile sensor networks are some of my current research focuses. Our research area initially emerged as performance analysis and application of optimal control in networks. Thie conceptual gaps as they emerge with advancements of new technologies like cognitive systems, adaptive beam forming, 5G and millimeter wave hardware, nanotechnologies are being addressed now. This process as it unfolds itself defines our ever evolving research agenda.
