DTN Use in Slovenian Karst Cave

An article published in  the scientific journal Natural Hazards and Earth System Sciences recognizes work of the N4C Community using (DTN) technology for automatic data transfer  in a huge karst cave system in Slovenia. The cave allows tourists, who ride a train deep into the cave, potentially exposing them to air quality health risks. DTN technology allowed the establishment of an early warning system (EWS) for poor air quality.  The experiment placed a DTN “data mule” (a DTN-enabled computer with WiFi connection) on the train. The data mule on the train received data from a meteorological station deep within the cave.  It transported the data to the train station at the cave entrance, which then updated the surveillance system, providing alert capabilities of deteriorating air quality conditions deep within the cave.  The full text of the paper is available here:
