Hello Nikola.  I'm Cc'ing Renzo Davoli, the main author of VDE, the
software layer we use to simulate the (cabled) Ethernet layer.  By the
way Renzo, you should be able to subscribe to the new list by clicking
"Subscribe" on https://launchpad.net/~marionnet-dev , after logging in.

We're not experts in ad-hoc networks, but I believe it could be done
quite easily *if* the underlying support is there.  It looks like a
rather big "if"...

...but the hardest part of the problem is solved by the UML support.
Great.  Anyway, we also have to emulate the "ether" layer: we rely on
VDE for cabled virtual networks; what should we use for wireless
networks? Renzo, can VDE help us in some way?  Are you informed about
what other simulation tools do?
  Simulating communication errors is just "nice" in cabled networks, but
 it's *crucial* for wireless networks, and ad-hoc networks in
particular.  I think we should simulate quantities like the signal
strength, and possibly even the physical location of mobile computers.
I suspect such a feature would be easy to retrofit into an existing
wireless simulation layer, if not already present.
  I'm just speculating but the thing sounds reasonable to me.  Please
correct me if I'm wrong.

So Nikola, I'm afraid the short-term answer is no, if you want to use
Marionnet for your research right now.  But wireless support is a
frequently-requested feature, and we should definitely implement it.
We're open to suggestions and code contributions :-).

Thank you for your interest,
