Re: [ns] gridkeeper

Hi!

I am changing the power used by the WirelessPhy
to transmit the packets by setting the Pt_ variable:

Phy/WirelessPhy set Pt_ 0.28183815

The above value is the default and results in a
transmissionrange of 250m. Changing it affects
the whole simulation in a very complex way...

Here are some values which I have tried myself:
0.18489 ==> 225m
0.11543 ==> 200m
0.03652 ==> 150m
0.007215 ==> 100m

If you are working with power control in ad-hoc
networks (like I am!) I'm very interested in
exchanging some experience!

Bye
Felix
