Ad-hoc wireless network for Emergency Workers

Ad-hoc wireless networks may soon tell emergency workers how to deploy transmitters.

Building an on-the-fly wireless communications networks is a vital part of firefighting, handling hostage situations, and dealing with other emergencies. But it is difficult to build such networks quickly and reliably.

Soon these emergency wireless networks could help build themselves. The National Institute of Standards and Technology (NIST) recently presented details of two experimental networks that tell emergency workers when to set down wireless transmitters to ensure a good signal.

Helicopter in Swiss Alps

PermaSense observes physical parameters related to permafrost in steep high-alpine terrain over a period of multiple years. Live sensor network data is transmitted from the Matterhorn, Switzerland field site at 3400 m a.s.l. every 2 minutes.

Gumstix verdex is the base station computer high on the mountain.

Gumstix on the Iceland icecap

The Glacsweb project used Gumstix (connex) together with a low power sensor board to control a sensor network installed in the summer of 2008 in the glacier ice of the main icecap in Iceland. The gumstix runs control scripts in Python to fetch sensor data from probes in the ice and a dGPS on the surface. It uses GPRS to copy data and fetch scripts from the server in the UK.
