The test revealed that although the main components of the health monitoring application are functional, there are still
shortcomings that restrict its practical use. The accelerometer and the analog-to-digital converter implemented in the
current generation of MICA2 motes do not possess the fidelity required for structural state evaluation. Resolution
problems due to quantization significantly affect the low level acceleration readings (Fig. 13). Communication packet
loss due to interference in radio transmission is quite pronounced at high sampling rates and with multiple motes
attempting to communicate simultaneously. This made the overall time required to download all accelerometer data
slow even with only three sensors. Receiving the data from a densely instrumented structure would take much longer.
Further improvements in self-organizing wireless networks and newer transmission strategies should help to address
this issue.
