WIRELESS UNDERGROUND SENSOR NETWORKS FOR MAGNETIC INDUCTION BASED COMMUNICATIONS ON THE AGRICULTURE FIELD

Electrical and Electronics Engineering

Wireless Underground Sensor Networks (WUSNs) constitute one of the promising application areas of the recently developed wireless sensor networking techniques. WUSN is a specialized kind of WSN that mainly focuses on the use of sensors at the subsurface region of the soil. For a long time, this region has been used to bury sensors, usually targeting irrigation and environment monitoring applications, although without wireless communication capability; WUSNs promise to fill this gap and to provide the infrastructure for novel applications. The underground wireless channel was only available recently. Communication through the underground medium has been a challenging research area .The applications require the deployment of sensors below the ground surface. Hence, the sensor become part of the sensed environment and might deliver more precise sensing. WUSNs, which have components, i.e. the sensors, that are buried underground and that communicate through soil. The majority of the applications for WUSNs – intelligent agriculture, environmental monitoring, of the soil. In this proposed system temperature of the soil in land is measured using the sensors and send it to the centralized server through IOT for monitoring. In case the measured temperature value in the soil is higher than the reference value, the measured temperature value transmitted via existing soil. We presents advanced channel models that were developed to characterize the underground wireless channel considering the characteristics of the propagation of EM waves in soil and their relation with the frequency of these waves, the soil composition and soil temperature.
