Career and research

Shroff and his PhD student Xin Liu and colleague Edwin Chong were among the first researchers to recognize the importance of opportunistic scheduling in wireless networks with short-term fairness [2][3] Opportunistic scheduling is the idea that variability in wireless channel quality can be exploited to maximize network throughput while taking into account some measure of quality of service. Using connections to convex optimization theory and stochastic approximations, he developed online opportunistic scheduling mechanisms that could guarantee a variety of explicit fairness guarantees. Opportunistic scheduling is now a part of the communication paradigm in every modern mobile phone.

Shroff with his PhD student Xiaojun Lin were among the first researchers to show that a network utility maximization framework of wireless resource allocation provides a mathematical interpretation of the functionalities of the various layers of the network protocol stack.[4] Specifically, by making a connection to Lagrange multiplier theory in convex optimization, they showed that queue length information shared across multiple layers provided the right feedback to design resource allocation algorithms for the transport, network and medium access control protocols.[5][6] These tools and techniques have now become standards in cross-layer network design and his survey paper [7] on opportunistic scheduling and cross-layer design was also influential in making the topic widely accessible to a large audience.

Shroff and his PhD student Sellke developed a novel technique to protect computer networks for Internet worms and viruses. combat the most dangerous form of computer virus. The technique automatically detects when an Internet worm has infected a network and signals network administrators to isolate the infected machine and quarantine them for repairs.[8][9][10]

Shroff is currently leading a large multi-organization team, composed of universities, private companies, and research labs, which has been selected by the National Science Foundation for developing new Artificial Intelligence techniques to design future wireless networks.[11]
