Development of wireless sensor networks for underground communication and monitoring systems (the cases of underground mine environments)

Empirical Evaluation of Wireless Underground-to-Underground Communication in Wireless Underground Sensor Networks

Many applications for irrigation management and environment monitoring exploit buried sensors wired-connected to the soil surface for information retrieval. Wireless Underground Sensor Networks (WUSNs) is an emerging area of research that promises to provide communication capabilities to these sensors. To accomplish this, a reliable wireless underground communication channel is necessary, allow...

Characteristics of Underground Channel for Wireless Underground Sensor Networks

Wireless Underground Sensor Networks (WUSN) constitute one of the promising application areas of the recently developed wireless sensor networking techniques. The main difference between WUSN and the terrestrial wireless sensor networks is the communication medium. The propagation characteristics of electromagnetic (EM) waves in soil and the significant differences between propagation in air pr...
