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." ;-) a.
