[O14] Distributed and Iterative Processing for Wireless Sensor Networks with Multiple Local Fusion Centres
Wireless sensor networks (WSNs) are becoming popular as wireless sensor nodes are matured with advanced sensor and wireless communication technologies. In general, sensor nodes are capable of sensing, computing, and communicating. Therefore sensor networks are widely used in military battlefield surveillance. However, at the same time, as most sensor nodes are battery-powered, some functions may not be fully utilized and limited by certain constraints. To overcome power constraints of sensor nodes, the use of multiple local fusion centers (LFCs) could be effective, which allows building the WSN in a layered manner. A LFC will collect information from closely located sensor nodes. Thus, sensor nodes can save power. To share measured information for better estimation, the LFCs in a WSN are connected through a certain wireless mesh network.
In this proposed project, we aim at developin:
i) distributed estimation methods at a local fusion;
ii) iterative cooperation communication mechanisms between LFCs; and
iii) performance analysis to optimize the performance with constraints.

Jinho Choi (Senior Member of IEEE) was born in Seoul, Korea. He received B.E. (magna cum laude) degree in electronics engineering in 1989 from Sogang University, Seoul, and the M.S.E. and Ph.D. degrees in electrical engineering from Korea Advanced Institute of Science and Technology (KAIST), Daejeon, in 1991 and 1994, respectively. He is now with School of Engineering, Swansea University, Swansea, United Kingdom, as a Professor/Chair of Wireless. His research interests include wireless communications and array/statistical signal processing. He authored a book entitled Adaptive and Iterative Signal Processing in Communications (Cambridge University Press, 2006). Prof. Choi received the 1999 Best Paper Award for Signal Processing from EURASIP, 2009 Best Paper Award from WPMC (Conference), and is a Senior Member of IEEE. Currently, he is an Editor of Journal of Communications and Networks (JCN) since 2005 and served an Associate Editor of IEEE Transactions on Vehicular Technology from 2005 to 2007 and ETRI journal. Since 2009, he joined the Editorial Board of International Journal of Vehicular Technology.
