question for expert

[mak coza]

dear expert,
i'm trying actually to simulate multi hope comunications between many nodes and one sink using ipv6 , i modify the wsn-ping.cc , but i have a little problem , the program  execute but without resulte , and an error ocured after execution say that its  terminated with signal SIGFPE.and when i try to run with the debuger a message say:
" File "/usr/share/gdb/auto-load/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.19-gdb.py", line 63, in <module>   from libstdcxx.v6.printers import register_libstdcxx_printers
ImportError: No module named 'libstdcxx' [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Best regards.

Ji,

I'm sorry but the info you provide are not enough to even start thinking to the error.

The only useful info is the SIGFPE. This is usually an error arising from a division by zero.

I'd strongly suggest to read the posting guidelines and a basic tutorial about C++ debugging.

i'm just trying to make a little WSN whith multihope communication with the node and the sink, i modified the wsn-ping6 , but i have this hard error.

Best Regards.

Hi,

I wrote a sarcastic message. I deleted it, you could not understand it.

I wrote an harsh message. I deleted it, other could be offended by it.

I tried to ignore your message, but you and others could not understand why I did ignore you.

Hence, I'll explain it. Once. Only once, because it is written in the posting guidelines.

Stating that you did modify something and that it's not working, and not providing info on WHAT you did modify and HOW makes it IMPOSSIBLE to guess the problem.

It's like calling the doctor stating "I did something and now I don't feel fine", and expect that the doctor can help you. You know what the doctor will suggest? To pray.

A bad news: praying doesn't work with coding.

T.

Hi,

despite the fact that you did NOT read the posting guidelines (because you blatantly ignored everything that is written in there), I did run your code.

It's not a SIGFPE, but a SIGIOT. Two completely different things.

Please run your code in a debugger, you'll find your mistake quite easily.

Please read one of the countless tutorials about how to use gdb.

Hi,

please read the posting guidelines (see the link below).

Moreover, please triple check your code. This line actually prevents packet generation.

      clientHelper.SetAttribute ("OnTime", StringValue ("ns3::ConstantRandomVariable[Constant=0]"));

[Jayasree Sengupta]

Sorry. I have now made the changes. Now please help me with what is wrong with the code. Why isn't it returning to the command prompt and why isn't it displaying the flow statistics.

[Tommaso Pecorella]

Hi,

again, please read the posting guideline (and learn how to use a debugger).

        Ptr<Ipv6FlowClassifier> classifier = DynamicCast<Ipv6FlowClassifier> (flowmon.GetClassifier ());

should be

        Ptr<Ipv6FlowClassifier> classifier = DynamicCast<Ipv6FlowClassifier> (flowmon.GetClassifier6 ());

Moreover, mind that a simulation of 100 seconds will take a LONG time, and its ascii trace will go over 10 GB easily.

T.

[Jayasree Sengupta]

Thank You so much for your help. Now it's all working fine.

But I did like to know what kind of routing strategy is this following (Since I am new to ns3 I have this doubt).

At the moment the LrWPAN model does NOT include the energy calculation, basically because the MAC model is not energy aware. Any number that you would get from it would be totally wrong.

Debug and test the repository here: http://code.nsnam.org/vrege/ns-3-gsoc/

Mind that:

1. It is an old ns-3 release. Any bug you can find in that release... well, I decline any responsibility.
2. The module itself is not yet fully reviewed. As before, I decline any responsibility for any bug or bad behaviour.
3. See points 1 and 2.
4. See points 1, 2, and 3.
5. See points 1, 2, 3, and 4.

I'm working to forward-port and integrate it in ns-3, but I have no idea about when the process will be finished. Unfortunately I have a zillion of chores, and they are all work-related.

Of course, if you want to help, any helping hand is more than welcome.

The most important priority is... testing it.
