Study on wireless underground sensor networks for remote irrigation monitoring system

Wireless underground sensor networks (WUSN) has wide applications in environmental information monitoring. It plays a vital role in the handling and management of water resources for irrigation. Because it prevents radio interference, improves real-time acquisition of information and reduces energy consumptions. In this work, WUSN was used to collect soil temperature and moisture information of an irrigation system. The base station used the sensor nodes to collect the data in a particular area. All nodes in the networks were the same and energies were constrained. According to the schedule, WUSN nodes turn on or off their radio module to save energy. When the collected data was less than the threshold value, the base station would inform the controller perform a motor control action through setting the corresponding. In this paper, system used data fusion method for saving energy to send collected data to the base station. The testing showed that the system was successfully implemented on a realtime remote monitoring for irrigation. The result was a low cost, highly reliable and simple infrastructure for the collection of soil data over a distributed area in agricultural environments.
