Wireless underground sensor network design for irrigation control: Simulation of RFID deployment

Abstract

Wireless Underground Sensor Networks (WUSN) using Electro-Magnetic (EM) wave communication has to address the challenges posed by the underground environment. An alternative to EM wave communication for WUSN is Magnetic Induction (MI). This research aims to study the possibility of using MI communication for WUSN designed for irrigation control in horticulture. As a case study, a typical Pecan farm in Australia has been considered. The case study would focus on the application of accurate soil moisture reporting and regulation for the farm, under all climatic conditions. This application addresses the issue of water-shortage confronting irrigation in Australia. This paper presents the results obtained from simulation of RFID deployment as part of WUSN design, and is a sequel to an earlier published work as part of an ongoing project.
