Abstract EN
Network-based wireless sensing has become an important area of research and various new applications for remote sensing are expected to emerge.
One of the promising applications is structural health monitoring of building or civil engineering structure and it often requires vibration measurement.
For the vibration measurement via wireless network, time synchronization is indispensable.
In this paper, we introduce a newly developed time synchronized wireless sensor network system.
The system employs IEEE 802.11 standard-based TSF-counter and sends the measured data with the counter value.
TSF based synchronization enables consistency on common clock among different wireless nodes.
We consider the scale effect on synchronization accuracy and evaluated the effect by taking beacon collisions into account.
The scalability issue by numerical simulations is also studied.
This paper also introduces a newly developed wireless sensing system and the hardware and software specifications are introduced.
The experiments were conducted in a reinforced concrete building to evaluate synchronization accuracy.
The developed system was also applied for a vibration measurement of a 22-story steel structured high rise building.
The experimental results showed that the system performed more than sufficiently.
