Research Interests: My research interests are in the wireless communications and networking. Currently my reseach focus is on the security aspects of sensor networks. I am working towards developing a reputation based framework for developing high integrity sensor networks. Over the past few years, I have been involved in lead role or as substantive collaborator in several sensor network projects: light weight ad hoc timing synchronization on mica motes, topology managment for energy-latency-density-accuracy trade-offs, localized and distributed approaches to estimation of aggregate functions and scalable post-deployment cryptographic key establishment.
