Yes, IMHO you *need* the real world simulations (and even then it is very easy
to make measurement mistakes and arrive at arbitrary conclusions [1]). I
started to only trust big real world deployments.
Thanks for the link, still have to read it in detail. BTW: the conclusion
section of this paper already confirms our previous discussion about reducing
txpower: "Currently hop counts up to 5 are achievable with routing protocols in
the full 7x7 grid when the power is set to 0dBm with 30 dB attenuators."
