Abstract

This paper presents the design and field tests of a Magneto-Inductive (MI) communication system for wireless sensor network applications. The proposed MI communication system utilizes three coils in a 3D spherical structure to improve the spatial sensitivity patterns and communication range. The sensor nodes equipped with a multi-coil MI system are designed to communicate at 125 kHz carrier frequency with 1 - 5 kbps data rate. Field tests in air and underwater demonstrate that the proposed sensor nodes can achieve reliable, low power communication at a range of 50 - 60 meters with a data rate up to 4 kbps.

Biography

Justin Hoyt is a senior undergraduate student in Electrical Engineering at the University of Missouri Science and Technology. He has been working as an undergraduate research assistant for Dr. Y. Rosa Zheng since April 2014. Through this research opportunity, he was given the distinguished task of presenting a paper related to this topic at the Underwater Communications Conference 2014 in Italy. Previously, he had a co-op with Ameren Missouri and has accepted an internship with Dynetics for the coming summer. He is currently a member of Tau Beta Pi, Eta Kappa Nu, and IEEE. After receiving his Bachelor’s Degree, he plans to pursue his Master’s Degree in Electrical Engineering.
