Re: [ns] NAM does not run wireless simulation over ns 2
try this command...
first as first remark
its preferable to work under this directory : /ns-allinone-2.33/bin and put
in it the trace file , the nam file and obviously the Tcl file..ok
second
i will suppose that you have done this.so to run the nam file :
exec ./nam /home/faraz/Desktop/ns-allinone-2.33/bin/attachment &
i hope that it will work

Re: [ns] NAM does not run wireless simulation over ns 2
Hi there,
In a wireless simulation for nam trace you have to use
$ns namtrace-all-wireless $nf $val(x) $val(y)
Hope it works,
Luis

[ns] NAM does not run wireless simulation over ns 2
Hello ALL,
I am trying to visualize the entire simulation using NAM. I open the .nam file
in the finish procedure. I have associated CBR source with one of the nodes to
make it send packets to another node. NAM executes properly at the beginning
(but does not show nodes at all), as soon as the scheduled time of sending
packets arrive NAM exits. Although it generates the trace file.
Please write back soon
