Monitoring of the LANDSLIDE Phenomenon using Wireless Sensor Networks

This paper presents a WSN-based method for monitoring the displacement in landslide susceptible slopes. In this method, an array of wireless transmitters installed on the target slope will broadcast regular signals, which will be received and interpreted by two synchronous receivers. The proposed system monitors the slope by measuring the phase difference between the two mentioned receivers before and after displacements, and shows promising reliability and accuracy for monitoring the status of landslide susceptible mountainous terrains. This approach did not have any field trial, but its results and accuracy has been evaluated through a series of comprehensive simulations performed for an array of six transmitter (Tx) and two receivers (Rx).
