[ns] [NS-ANS] Re: Needed awk script for throughput in wireless scenario
Hi, If you are interested in learning how tracing works in NS2, please read http://www.ns2ultimate.com/post/3995318343/post-processing-ns2-result-using-ns2-trace-main-post The above posts are based on the normal trace. If you are interested in wireless trace you might have to modify it a bit.

Re: [ns] Problem in GPSR implementation
Hi, A lot of people are having the same problem. I am curious why. My guess is just because the GPSR are not incorporated to NS2 properly.

Re: [ns] about command $ns rtmodel-at 1.0 down $n(1) $n(2)
Thanks for your reply!
but there is no command Iif in tcl/lib/ns-link.tcl.
it is
Link instproc all-connectors op {
foreach c [$self info vars] {
$self instvar $c
if ![info exists $c] continue
if [array size $c] continue
foreach var [$self set $c] {
if [catch $var info class] {
continue
}
if ![$var info class Node] { ;# $op on most everything
catch $var $op;# in case var isn't a connector
}
}
}
}
However ，the script can run successfully on NS-2.26.
Thanks!

I just download the example script without any modifization.
If I comment out the commands

#$ns rtmodel-at 2.0 up $n(1) $n(2)
The example can run succefully.
How can this happen?
Thanks very much!
Re: [ns] RTP over wireless connection between two nodes

[ns] How to pass multiple objects from oTcl to c++ ???
Hi,
Anybody knows how to pass multiple objects from oTcl to c++ ??
For example I want to retrieve 2 link head object ( link_($src1:$dst1) and
link_($src2:$dst2) ) from oTcl calling from C++ Simulator class
NsObject* Simulator::getTheLinks(ParentNode *src1, int dst1, ParentNode
*src2, int dst2 ) {
Tcl tcl = Tcl::instance();
tcl.evalf([Simulator instance] get-link-head %d %d %d %d,
src1-nodeid(), dst1, src2-nodeid(), dst2);
}
Assume that the Simulator get-link-head instproc will return 2 links head in a
form of list or arrays
return links [list link_($src1:$dst1) link_($src2:$dst2)]
So now how to retrieve those 2 links head and associate them to different C++
NsObject *pointers using tcl.result() ???

Re: [ns] How to change energy config of perticular mobile node in
Since the node-config is set in the Simulator instance, the first thing that comes to my mind is to set up node-config in Simulator instance for every single node you want and then start your simulation. I'm pretty sure this is not the best way. On Tue, May 10, 2011 at 8:42 PM, Bipul Chandra bipu...@gmail.com wrote: Hi, I am doing my simulation on ad-hoc network and i am using NS-2.

My previous answer is wrong i think but you get the point. You need to
return (TCL_ERROR) at the c++ function that was called by TCL.
You can then catch the error at your tcl script and do what you want
when that error is raised.

You mean stopping completely or pausing and then resuming the

Is it possible to be done?
