Structure Monitoring using Wireless Sensor Networks CS294-1 Deeply Embedded Network Systems

Structure monitoring brings new challenges to wireless sensor network: high-fidelity sampling, collecting large volume of data, and sophisticated signal processing. New accelerometer board measures tens of μG acceleration. High frequency sampling is enabled by new component of David Gay. With new component, up to 6.67KHz sampling is possible with jitter less than 10μs. Large-scale Reliable Transfer (LRX) component collects data at the expense of 15% penalty of channel utilization for no data loss. To overcome low signal-to-noise ratio, analog low-pass filter is used, and multiple digital data are averaged. Structure monitoring is a driving force for extending capability of wireless sensor networks system.
