In order to help students better understand and master the channel propagation characteristics of wireless underground sensor networks(WUSN),this paper derives and establishes an improved underground wireless channel propagation model that incorporates soil property parameters.Based on this model,a virtual simulation experiment system for WUSN is developed.This virtual simulation system not only solves the problem of limited experimental environment and difficulty in conducting experimental teaching but also has the advantages of easy understanding and operation,with calculation results presented in a graphical and visual format.Through this system,students can intuitively observe and compare the changes in underground wireless channel propagation under the influence of different parameters,thereby gaining an in-depth understanding of the complex propagation characteristics of underground wireless channels.This not only enhances the students'learning efficiency but also effectively stimulates their interest in learning,fostering proactivity and enthusiasm in their studies.
