Network Design and In-network Data Analysis for Energy-efficient Wireless Sensor Networks of Bridge-Monitoring Applications

In this talk, I will focus on the network design and in-network data analysis issues for energy-efficient wireless sensor networks (WSN) in the context of bridge monitoring applications. First, I will introduce the background of our research, a project funded by the U.S. National Science Foundation. Then I will discuss the history of the critical communication radius problem in wireless sensor network design, and explain our result of determinate upper and lower bounds of the critical radius for the connectivity of bridge-monitoring WSN in detail. Finally I will describe a distributed in-network data analysis algorithm for energy-efficient WSN performing iterative modal identification in bridge-monitoring applications.
