Abstract—Wireless underground sensor networks (WUSN) are a natural extension of the wireless sensor networks (WSN) phenomenon to the underground environment. In this work, experimental measurements are presented at the frequency of 433 MHz, which show a good agreement with the theoretical studies. Experiments are run to examine the received signal strength and the packet error rate for aboveground-to-underground and underground-toaboveground communication links. The results reveal that the effects of burial depth, inter-node distance and volumetric water content of the soil on the signal strength and packet error rate. The tests show that the communication range decreased when the soil moisture increased.

Index Terms—Wireless underground sensor networks, communication, depth, inter-node distance, volumetric water content
