My research interests lie in the area of Distributed Control Systems and Networked Control Systems. I am particularly interested in understanding how to integrate Ad-hoc Wireless Sensor Networks into control systems, specifically how to design the network communication layer to provide good performance for control applications operating over the sensor network. This involves understanding how latency and the loss of observation and actuation packets affect the performance of estimators and controllers, and applying congestion control and reliable routing algorithms to meet the requirements the control systems impose on these parameters. At a higher level, I am also interested in understanding how to decompose global optimization problems into local optimization problems such that it can be solved by a distributed optimization solver connected by limited, lossy communication. The focus would be on finding problem decompositions such that the corresponding solvers are stable and converge to a solution quickly.
My Ph.D. Dissertation is titled: Wireless Sensor Network Metrics for Real-Time Systems.
The focus of my recent research has been on characterizing the reliability of hop-by-hop routing on interleaved mesh routing topologies. I'm actively involved in the IETF ROLL (Routing Over Low power and Lossy networks) working group on the development of RPL (Routing Protocol for Low power and lossy networks), a mesh hop-by-hop routing protocol. I have reviewed some of the drafts and provided comments.
