Engineer Receives NSF Grant to Improve Sensor Networks

Monday, August 6, 2007

Yong Chen, assistant professor of mechanical and industrial engineering and researcher in the Center for Computer Aided Design (CCAD) in the University of Iowa College of Engineering, has received a three-year, $181,501 National Science Foundation (NSF) grant to help improve performance of distributed sensor networks.

Chen will serve as principal investigator for the project titled "Collaborative Research: Fault Tolerance Analysis and Design of Clustered Sensor Networks."

"The objective of this research is to provide solutions that enable efficient fault-tolerance analysis of clustered sensor networks and further establish a design method for achieving a robust and reliable system," Chen says. "This fundamental research will contribute broadly to the applications of radio-frequency identification (RFID) networks used in manufacturing enterprises and other types of wireless sensor networks. The application of fault tolerance analysis and design methods will lead to reliable operations and reduce the occurrence of false positives in distributed sensor networks."

Chen says that RFID networks can help improve operating efficiencies in manufacturing systems by automatically detecting product movements and tracking inventories. Distributed sensor networks currently have broad applications, ranging from environment monitoring and traffic control to battlefield surveillance.

Chen, who received his master's degree in statistics and doctorate in industrial and operations engineering from the University of Michigan in 2003, has fields of knowledge that include statistical learning and fault-tolerant sensing.
