| Zusammenfassung |
| The paper presents an experiment demonstrating a novel and successful
application of delay- and disruption-tolerant networking (DTN) technology for
automatic data transfer in a karst cave early warning and measuring system.
The experiment took place inside the Postojna Cave in Slovenia, which is open
to tourists. Several automatic meteorological measuring stations are set up
inside the cave, as an adjunct to the surveillance infrastructure; the
regular data transfer provided by the DTN technology allows the surveillance
system to take on the role of an early warning system (EWS). One of the
stations is set up alongside the railway tracks, which allows the tourist to
travel inside the cave by train. The experiment was carried out by placing a
DTN "data mule" (a DTN-enabled computer with WiFi connection) on the train
and by upgrading the meteorological station with a DTN-enabled WiFi
transmission system. When the data mule is in the wireless drive-by mode, it
collects measurement data from the station over a period of several seconds
as the train without stopping passes the stationary equipment, and delivers
data at the final train station by the cave entrance. This paper describes an
overview of the experimental equipment and organization allowing the use of a
DTN system for data collection and an EWS inside karst caves where there is
regular traffic of tourists and researchers. |
