Channel modeling for MI-based wireless underground sensor networks with conductive objects
摘要
We develop a comprehensive and accurate channel model forMI-WUSNs by taking into account the impact of multiple conductive objects located in different positions. The mathematical expressions for mutual inductance and received power are rigorously derived for each case. Extensive experimental results have verified our theory. Hence, this paper provides a solid foundation for subsequent system design for MI-WUSNs.
