In general, we were pleased with our systems’
performance. During the 19-day deployment, we
retrieved data from the network 61 percent of the
time. Many short outages occurred because — due
to the volcano’s remote location — powering the
logging laptop around the clock was often impossible.
By far the longest continuous network outage
was due to a software component failure,
which took the system offline for three days until
researchers returned to the deployment site to
reprogram nodes manually.
Our event-triggered model worked well. During
the deployment, our network detected 230
eruptions and other volcanic events, and logged
nearly 107 Mbytes of data.
