WUSN testbed results (UG2UG) with commodity WSN sensor nodes. RSS for dry and wet soil scenarios. Comparison between underground and over-the-air wireless communication.Effects of soil moisture over underground communication [4]. Burial depths of the sender and the receiver: = 40 cm. Internode distance: = 30 cm.Wireless underground communication channel: high stability [4]. Burial depths of the sender and the receiver: = 40 cm. Internode distance: = 50 cm. Transmit power: +10 dBm.
