use ifdefs to NOT redefine abort in those RNG files
as such, you'll see aborts everywhere except RNG fucntions

I am working on a project to study the effect of channel errors over a
wireless link. I have read chapter 13 of the NS2 manual and I am not
quite clear as to how to implement the error model in ns2. Any pointers
will be accepted.
Thanks,

Hi list
The proposed work around sounds interesting and I took the chance to put
it on the wiki: http://nsnam.isi.edu/nsnam/index.php/Hacks
Please extend the wiki with your results for this issue.
Also, if you have any other "hacks" or code snipplets that you created
in order to make you ns-2 experience more smooth, please add it there also.
Thanks a lot,
Claus

Hi Nabila,
looks like you only declared ns as a global variable inside your
procedure. Is this sufficient? I am not sure, but maybe reading up on
local variables and their scope in tcl is a starter...
Please add any insight you gained into the ns2 wiki
(http://nsnam.isi.edu/nsnam/index.php/Main_Page) so that others can
learn about and from your work.

This seems to be the message printed by wireless.tcl shortly before it
sources opt(sc) [which is your mit/uAMPS/...
OK the follwoing (I guess) refers to stuff from your uAMPS file

which means that somewhere in your uAMPS file the $opt(topo) is sourced:

The question is: what topography do you want to load? is mit/uAMPS/... a
valid scenario file? It doesn't look like that to me from what i see
here...
I would simply recommend to simply set $opt(topo) in the tcl file to
whatever you wnat it to be and forget about the command line.
set opt(topo) "PATH/TO/WHATYOUWANT"

Dear Samir
I read one of your ns list message regarding post processing of trace files.
You wrote:
grep -e "r -t " output.tr > temp1.tr
grep -e "tcp -Il $rpktsize" temp1.tr > temp2.tr
grep -e "-Nl AGT " temp2.tr >
datarecv.tr
" All these steps are done automatically by a certain software written in
tcl and matlab that I did it for my own simulations"
Do you mean that all of these grep commands can be run in TCL? and how about
matlab?
thanks
basim

Hi claus,
Great thing that you are doing for NS2 - definitely, what the NS2 wiki needs
is the persons that are aided in any way, should post their findings in the
wiki. That's exactly what I'm requesting since some time:
http://tagus.inesc-id.pt/~pestrela/ns2/
"Call for volunteers: If you find these help pages useful, please volunteer
some of your time to help other NS users, by moving these pages into the new
NS2 wiki. More information here and here. Thanks!"

Subject: [ns] Implementation of AODV in NS
To: <[email protected]>
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset="iso-8859-1"
Hi All,
I'm trying to modify AODV protocol in NS e.g delaying the forwarding
of route request packet by intermediate node.
Does anyone know the part of NS code and can modify to achieve this?
I've modify the code but seem to not to be achieving the desired
result.
Also if a packet have been schedule using
Scheduler::instance().schedule();
How can one stop or delete the schedule for the given event ?
Regards
Olakunle
