A Wireless Sensor Network Innovative Architecture for Ambient Vibrations Structural Monitoring

Wireless sensor networks can be beneficial for monitoring ambient vibrations in historical buildings where the installation of traditionally wired system may be either difficult due to wiring difficulties or forbidden due to prohibitive legislation. In this paper, a novel wireless sensor network architecture is presented that is focusing on efficiently monitoring ambient vibrations in historical buildings. Traditional wired monitoring technologies are often difficult to be installed in historical buildings either to high costs for installing the wires or to prohibitive legislations. Employing a wireless system could be beneficial. However, as there is no wireless system of high resolution available in the market, an innovative network architecture is proposed that efficiently combines the benefits of both the wired and wireless systems. The problem of synchronization that this novel architecture introduces, is also discussed in this paper along with a possible solution.

Innovative System

The problem of bridging the gap between the traditional wired monitoring systems and the wireless ones, was the objective of an innovative network architecture that elegantly combined benefits from both approaches. The monitoring focus is on historical buildings in which installing wires maybe range from difficult (e.g., fragile constructions) to impossible (e.g., prohibitive legislation). However, this innovative approach is vulnerable with respect to synchronization issues. In particular, all data sensed by different sensors need to have the correct universal time stamp. Since under this approach there is no central entity to take a synchronization role, in this paper the use of a local NTP server is proposed and as it is shown here using experimental results, this approach suffices for the particular monitoring needs. Thus, the claim that the innovative system can efficiently support the required monitoring of ambient vibrations in historical buildings.

We present a wireless system applied to precision agriculture, made up of sensor nodes that measure soil moisture at different depths, applied to vine crops where drip irrigation is applied. The intention is to prepare a system for scaling, and to create a Wireless Sensor Network (WSN) that communicates by radio frequency with a base station (ET), so that the gathered data is stored locally and can be sent out an Internet gateway.
