As wireless sensor networks (WSNs) have developed over the last decade, environmental scientists have widely adapted this new technology to monitor various phenomena in the natural environment, for example, debris flows, pollution, volcanoes, and so on. However, significant efforts are still needed to customize WSN design for certain special requirements. To remedy the redundancy of efforts to customize...
Vibration is the main reason for earthen sites to deform and collapse. It is necessary to get vibration data for providing basis to further conserving earthen sites. Traditional monitoring methods are not suitable for the earthen sites because it is destructive and unsustainable. We use the technique of wireless sensor network (WSN) to get the vibration data, and delve into how to transmit large amounts...
Wireless Sensor Networks (WSNs) leverage battery-powered embedded devices to sense from and act on the environment. Their characteristics are at odds with the lifetime requirements in monitoring of civil structures. In this paper, we briefly describe the challenges at stake and how to address them, drawing from recent literature and our own real-world experience. Hardware solutions include MEMS sensors...
Modern engineering systems are becoming increasingly complex, sophisticated, demanding and globally distributed. Maintaining and sustaining such systems healthy, reliably, safely wherever and whenever needed efficiently and economically is a challenging task facing the 21st century. It is gratifying to note that significant advances are being made by researchers from academia, public and private R...
The present paper proposes a wireless sensor network in order to verify the building structural health by monitoring the vibration levels transmitted. In particular the network allows to assess if the vibration levels may cause damage to the building or if it needs further study. The vibration levels are compared with fixed thresholds suggested by studies and regulations. The attention has been focused...
