چکیده
Hybrid Wireless Underground Sensor Networks (WUSNs) is an emerging area of research that promises to provide communication capabilities to buried sensors and aboveground devices. In this work, experimental measurements are presented at the frequency of 433MHz for short-range distances (<15m). The effects of the soil moisture and the maximum physical distances are some of the investigated aspects.

متن کاملDevelopment of a new wireless sensor network communication
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-un...
متن کاملReliability-Aware Power Adjustment in Air-Soil Wireless Sensor Networks
We study the power conservation and disseminating reliability problem in precision agriculture applications in this paper. Precision agriculture needs to accurately evaluate farming environment, and soil monitoring is an important part of this effort. Soil measurement requires soil sensors being buried deep enough so as to avoid plowing and other mechanical activities. Due to dielectric loss, r...
متن کاملExperiment Measurements for Packet Reception Rate in Wireless Underground Sensor Networks
A Wireless Underground Sensor Network (WUSN) is a network of wireless sensor devices in which all sensor devices are deployed completely underground (network sinks or any devices specifically for relay between sensors and a sink may be aboveground). These networks can be utilized to monitor the underground environment, especially soil conditions and aboveground events, such as the presence of p...
