Re: [ns] how to use awk script
Hi Robin,
Isn't that obvious? It's because your denominator is zero. You can't compute

I've installed ns-2.35 from official ubuntu repositories, but I couldn't find setdest executable in order to generate mobility traces for my ad-hoc simulations. I've been looking for this tools in google but I found nothing. Any idea of how can I compile it? I think it's something like perl/python script instead of a .c/cpp code, but anyway I don't know where can I get it. Thanks in advance, -- == Javier Cancio del Busto ==
[ns] [NS-ANS] Re: Setdest (mobility model)
Hi, The utility setdest is a standalone utility. It must be invoked at the command prompt. The utility is located in the directory ns-2.35//indep-utils/cmu-scen-gen/setdest. Go to that directory and execute ./setdest -v 1 -n 50 -p 0 -M 20 -t 900 -x 1500 -y 300 The utility will create Tcl mobility statements for you. You can copy these commands and insert into your NS2 Tcl simulation script. But generally, the above run would create too many Tcl statements. You can store all the statements in a file 'out.txt' by running ./setdest -v 1 -n 50 -p 0 -M 20 -t 900 -x 1500 -y 300 out.txt Then you can copy the mobility statements from the file out.txt to your NS2 Tcl simulation script.

[ns] [NS2-ANS]Re: segmentation fault
Hi, Segmentation fault is usually due to memory access violation. A common example is as follows. int x[10]; x[20] = 0; where you create an array x with 10 slots, but try to access 20th slot of x. Another cause is the misconfiguration. You might send packets to a object which does not exist.

Dear Tom, Thanks for your comments. It is quite hard to find a moderator, indeed. It would be hard to do so. I'm not quite sure how to fix the problem, except for putting [NS-ANS] tag on the subject. A lot of mail clients can do the filter and shows on the answer. In fact, what I have done so far is as follows. I've been blogging about NS2 regularly at ns2ultimate.com. When I see the question that can be answered with my blog, I just refer those people to my blog. For those who do not ask responsibly, e.g., please send me the source code of protocols, I direct them to my blog post on Ethic. http://www.ns2ultimate.com/post/535741560/assistance-and-ethics Best Regards, Teerawat On Aug 16, 2011, at 4:03 PM, Mariam A.

In fact the really gain from this guideline is sending the answer using RELPY TO ALL, this will save the answers. Kindly, if you have any other suggestions, please share with us. Thanks Mariam Here are a few thoughts on this topic. This issue has been around for as long as the list itself (~15 years) and admins have tried to deal with it through various mechanisms: - First-time posters bounce message - Monthly FAQ on ns-2 sent out automatically - Make people subscribe through a gateway web page that asks them to follow list rules. (http://www.isi.edu/nsnam/ns/ns-dev-list.html has done this for the developers list) Despite this, some people will always ask the list first, without searching. This will be unavoidable in an unmoderated list. I think there are two basic options here: 1) (moderated) more intrusive moderation of the list, and bouncing inappropriate questions from first-time posters with some suggestions about how they need to improve their question. This is probably nicer for everyone on the list (improving signal to noise ratio) but is a lot of work for the moderator. 2) (unmoderated) keep up with some combination of what we are doing now, perhaps with some updates from the ideas in this thread Unless someone or some small group of individuals wants to take on active moderation duties (note, I do not want to do this myself), I think that some of the ideas in this thread can be used to enhance what has already been done; namely, an (improved) monthly FAQ/posting guidelines reminder, also sent to new list members if possible upon successful subscription, the first time posters bounce script, and having people click through a web page with the posting rules, before getting to the subscription page. Another thing we have been doing occasionally on ns-3 is to try to answer some FAQs by writing the answers on a wiki page, and point people to this wiki in the reply, rather than answering in line on the list: http://www.nsnam.org/wiki/index.php/HOWTOs Then, people discover the presence of this wiki. If someone wants to be a wiki curator of an ns-2 FAQ/HOWTO, we could set that up too. - Tom

Re: [ns] error in arq insertion in tcl code
Hi Bibhu,
Link-loss model is used in a wired network. In wireless networks, you will have
to use other approach (e.g., propagation model) to impose error on the link.
Mobile node has different architecture than regular nodes. The ARQ module would
still work. But you will have to find another place to attach the ARQ module.

[ns] [NS-ANS] Re: How do I calculate the node utilization?
Hi Ahmed, In NS2, things happen very briefly in node. If you are working in a wired network, things happens in Simple link. For example, the queue is not associated with nodes (as in the physical world), but with the link. So you can't really find the utilization of the node. But if you are interested in finding link utilization. You may find it from link throughput / link capacity. I blogged a series on how to post-process NS2 result. You can find link utilization computation example from the link below: http://www.ns2ultimate.com/post/3442965938 Best Wishes, Teerawat Issariyakul http://www.ns2ultimate.com/ http://www.facebook.com/pages/Teerawat-Issariyakul/358240861417 http://twitter.com/T_Bear http://www.t-issariyakul.blogspot.com http://www.ece.ubc.ca/~teerawat On Feb 22, 2011, at 10:13 AM, Ahmad wrote: Hi all, Trying one more time just incase.

Re: [ns] Why do we have this group?
Hi,
The problem with the latter one (i.e., when a questioner gets the answer,
repost the answer back to the mailing list) is that the person who's got the
answer may not forward the answer back to the mailing list. Even when you have
the rule written say in FAQ, new persons who recently joined the mailing list
might not know about the rule. Then, they would not forward the answer back to
the mailing list.
In my opinion, reply all with a simple tag [ANS:NS] or something like this
might work. People will know that this email message is an answer to a certain
question. Those who do not care about the answer can immediately delete it.
They may event get their mail client to delete mail whose subject contain
[ANS:NS].
But we need to come up with an agreed-upon tag for answering the question.
Note that one drawback of this approach is that there might be too many email
about the reply, which might annoy our members.

Re: [ns] Why do we have this group?
Hi Hadi,
Thanks for the support. I understand that you'd like to make tag more specific
to fit the readers' need. However, there is a wide variety of question in this
mailing list. For example,
- Installation basic NS2
- Installation of patch (which some people don't even know that they are
patching their NS2. They think that they ran into weird problems.)
- Segmentation fault
- Including new protocols
- No-slot (classifier) errors
- OTcl and C++ linkage (e.g., evalf, resultf,...)
- Protocol specific questions (IEEE 802.11, Energy, routing, etc.)
These are just few examples I've seen over past year. If we assign a tag to
each of the categories above, before long we're gonna have to maintain a long
list of tags.
Now the next problem is that the anwerers will have to remember the exact words
of the tags to conform with the standard we are trying to set here.
Another problem is that with more complicated tag, you cannot ask your mail
client (e.g., mail rules in Apple mail) to automatically delete the mail which
contains a certain tag (e.g., [NS-ANS]).
Anyway, thank you for your thought. I hope we can help each other make this
mailing list a better place.

Hi all,
I agree with Teerawat, the replay to all with special tag is more
efficient , However we can define special tag for different questions :
For example I have noted that most of the question is related to the
problem of installation : ns2.29 on ubuntu , on fedora , bad version of
gcc..
I propose to add [ANS:Install:NS] for replay to problem of installation
[ANS:MAC:NS] for mac questions and so on ...
if I am not interested to reply or read to one category I will just have
to delet them easily by creating folder.

HI, NS2 implements buffering in link, not in node. This is to model the link with large bandwidth-delay product.
