Hi,
I have a question about CMUTrace objects in MobileNode
I am using ns-2.1b5 for my research, and I have tried
~ns/tcl/ex/wireless.tcl for excample.
It works, but in my trace file, there is only movement
infomation was writtten. Just like this,
--------
M 0.00000 50 (389.15, 135.17, 0.00), (980.77, 258.91), 16.04
M 0.00000 49 (594.42, 281.89, 0.00), (1001.75, 206.83), 14.95
M 0.00000 48 (485.88, 63.15, 0.00), (260.39, 16.42), 8.09
M 0.00000 47 (81.41, 237.01, 0.00), (952.06, 102.89), 19.72
M 0.00000 46 (923.57, 14.68, 0.00), (1067.65, 125.52), 9.88
M 0.00000 45 (234.35, 181.87, 0.00), (1386.88, 147.53), 10.78
M 0.00000 44 (261.48, 82.50, 0.00), (1389.91, 286.60), 18.46

This trace file does not contain any infomation about
packets. And I do need packet infomation, as it from
cmu-extendedns. Like
------------
SF 22.473590906 _20_ --- 2 [20 -> 18] [|20 18 ]

----------------
To get a result like this, I have to use CMUTrace objects
in my scripts, but I could not find the way to enable it.
With source code of cmu-extendns-1.1.0. I have found
following problems.
1.In file ~ns/tcl/ex/wireless.tcl #66
MacTrace is OFF. It must be ON
2.In ~ns/tcl/lib/ns-mobilenode.tcl #121 (in function Node/MobileNode)
Code related to CMUTrace was commented out.
It seems I cannot use CMUTrace with default settings.
What should I do to use CMUTrace object in ns2?
Or should I use cmu-extened one instead?
Thanks for your help
