Survey on Water-saving Agricultural Internet of Things based on Wireless Sensor Nerwork

Abstract

© 2015 SERSC. Wireless Underground Sensor Networks (WUSN) have the potential to impact a wide variety of novel applications including intelligent irrigation, soil information monitoring, etc, the internet of tings for water-saving agriculture. WUSN consist of wireless devices that operate below the ground surface. These devices are buried completely under dense soil. The main difference between WUSN and the terrestrial wireless sensor network is the communication medium. This work provides an extensive overview of the research and application situations in agricultural internet of things for WUSN. The water-saving agricultural internet of things based on WUSN architecture is developed. Here, the main research for the underground communication channel including methods for predicting signal losses in an underground link. Based on the test model, research tests and results are discussed.
