We used the messh concept back in 1995 or 6 I think
for the SNOW-POLE system PACcomm built for the
Army for use in Czech Republic. It is when PacComm
introduced the original callsign substituting TNC's
so that once a snow-pole had digipeated a packet
it would not digipeat that packet again. (That
was our RELAY system).
Problem was it would repeate all the other copies though
of its own packet digipeated by others. That is the
RELAY dupe problem that we have finall gotten around
to forcing obsolete in 2004 to avoid all those dupes.
I proposed the WIDEn-N system back in 1994 but it
wsa not until 1998 that Kantronics put it in their TNC's.
It is a perfect MESH system. Every station digipeats
it once and never again.

Has anyone come up with an APRS-based environmental telemetry sensor for EMCOMM use?
Specifically...having a "sensor/APRS kit" that one could drop-or-deploy into a theater and let it beacon back telemetry that would be of use to emergency first and second responders.
* Wind speed, wind direction, temperature, humidity ... for chemical spills or forest fires
* Water level ... to help manage flooding
* Air transparency ... to help manage air pollution
Either drop-and-forget (like around a forest fire) or purposefully deploy (like, ahead of a flooding event)...but with the expressed purpose of providing valued telemetry of known quality.
