英文摘要: This project aims at studying wireless underground sensor network, works to research the general characteristics of fixed frequency electromagnetic wave through-the-earth and underground transmission in cultivated horizon soil by using the developed low power wireless underground sensor network nodes, and the effect of the soil water content and the inter-nodes distance on the transmission characteristics. On the basis, wireless underground sensor network electromagnetic wave transmission models in the soil and air are established by adopting the combination of the experimental analysis and numerical simulation methods according to the theory of electromagnetic wave transmission, which provides technical support for wireless underground sensor network deployment in soil environment and the establishment of the system.
