Abstract: Structural health monitoring with wireless sensor networks has received much attention in recent years due to the ease of sensor installation and low deployment and maintenance costs. However, sensor network technology needs to solve numerous challenges in order to substitute conventional systems: large amounts of data, remote configuration of measurement parameters, on-site calibration of sensors and robust networking functionality for long-term deployments. We present a structural health monitoring network that
addresses these challenges and is used in several deployments for monitoring of bridges and buildings. Our
system supports a diverse set of sensors, a library of highly optimized processing algorithms and a lightweight
solution to support a wide range of network runtime configurations. This allows flexible partitioning of the
application between the sensor network and the backend software. We present an analysis of this partitioning
and evaluate the performance of our system in three experimental network deployments on civil structures.

TL;DR: The FTSP achieves its robustness by utilizing periodic flooding of synchronization messages, and implicit dynamic topology update and comprehensive error compensation including clock skew estimation, which is markedly better than that of the existing RBS and TPSN algorithms.

TL;DR: It appears very hard to significantly improve upon the rate obtained by Deluge and it is argued that the rates obtained for dissemination are inherently lower than that for single path propagation.
