Research

My primary research interests lay in the area of wireless sensor and mobile ad hoc networks. In particular, I am interested in energy-efficient data dissemination, coverage, connectivity, and fault-tolerance in wireless sensor networks. Specifically, my research focuses on the design, analysis, and implementation of optimized and localized fault-tolerant, energy-efficient data dissemination and topology control protocols for promoting the longevity of wireless sensor networks. Another facet of my research work is concerned with the design of secure, adaptive, and fault-tolerant architectures for connecting wireless sensor and mobile ad hoc networks to the global IP Internet with a goal to provide the user with seamless ways to access the sensed data. In my research, I use fundamental concepts and models from computational geometry, such as Voronoi diagram and Delaunay triangulation; graph theory, such as connectivity and conditional connectivity; and physics and chemistry, such as percolation theory.
