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...
متن کاملCharacteristics 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...
متن کاملPlant Competition Underground
Belowground competition occurs when plants decrease the growth, survival, or fecundity of neighbors by reducing available soil resources. Competition belowground can be stronger and involve many more neighbors than aboveground competition. Physiological ecologists and population or community ecologists have traditionally studied belowground competition from different perspectives. Physiological...

متن کاملCompact Underground Radar System
Pulse radar systems, known as subsurface interface radars, have been widely used to locate underground objects. Three-dimensional towershaped antennas were developed to replace conventional plane antennas and accurately detect the location and depth of underground objects like gas pipes, water pipes and transmission cables. The newly developed radar system using these tower-shaped antennas is c...
