Abstract:
Most underwater wireless networks have used acoustic waves as the transmission medium, but the chances of getting much more out of acoustic modems are quite remote.Optical links are impractical for many underwater applications. Given modern operational requirements and digital communications technology, electromagnetic waves can offer great potentials to underwater applications, particularly in shallow water conditions. A small scale underwater wireless sensor network is designed for coastal monitoring purposes, using very low frequency electromagnetic communication system. The lightweight protocol is time division based in order to fit the unique characteristics and specifications of the network. Evaluations are based on initial beach trial as well as modelling and simulations. The results demonstrate the likely effectiveness of the designated network.


Bio:
Dr. Xianhui Che (Cherry) works in the School of Applied Computing at Swansea Metropolitan University, United Kingdom, as the role of Senior Lecturer (equivalent of Associate Professor in Asia) and PhD supervisor. She obtained her B.Eng. degree in Computer Information and Network Systems from North China Electric Power University,Beijing, in 2001, and her M.Sc. in Telecommunication and Information Systems from University of Essex in UK in 2002; the same year, she was granted a full Ph.D. scholarship by the University and Intel Research Centre in UK. She gained her doctorate degree in Electronic Systems Engineering in 2006. She has been involved in several projects throughout her research pathway and delivered various publications. Her research interests include TCP/IP data networking, control protocol design, network modelling and simulations, optical and wireless networking, and game networks. She has been reviewing papers for several academic journals and conferences.
