Check out this article on DARPA network stuff:

I see this research as part of the soldier net ad hoc network scheme. Small
bits of data such as

-ALPHA TEAM GO 210 500M.  HOLD POSITION BELOW RIDGE
LINE-

interesting stuff. We were talking about something like this a few weeks ago
in regards to SG comms.

Blue tooth, 802.11b, 802.11g and all that certainly provide enough of this for
ideas. The only major problem is that if you're emitting RF, you're easier to
detect. Your unit has to spend time dropping other dummy emitters to
compensate and muddy the waters to keep your enemy's information value to a
minimum. Now, laser based signals or something that is very short ranged would
help, but lasers need fancy controls to keep it all tuned and low power
transmitters can still be detected with good strong signals.

Though, to be honest, if you're in combat, they probably already know you're
there. Your greatest problem up to then is keeping your signals quiet until
you make contact so as to prevent giving your positions away. A burst transmit
type system would be best, how to build that in real world is certainly
tricky.

Ryan,

I think that is what they are trying to make. Very low power network with
smarter packets. Network forms without oversight from above and passes packets
onto a node that leads towards its destination. Still have some of the
emitting that you are talking about but with low enough power you would not
know that this is going on until they are in combat range.
