Dynamic Characterization of Buildings Using Wireless Sensor Networks

Abstract eng:
Dynamic characterization of structures is a tool that can help to determine its actual state. Also, allows calibrating finite element models. Traditional methods use a centralized data acquisition system. This approach is not scalable since the cost of each channel may forbid it. A new paradigm to instrument structures uses smart sensors, capable of wireless data transmission, and local processing. With this technology is possible to eliminate the use of cables and reduce installation time. First the best location for the sensors is established based on modal participation of the sensor placements. The second task is to design a network capable to transmit the data in the most fashionable way. The objective of this paper is to present two different networks that together permit transmitting data collected over the structure without buffer overflow.
