[ns] How to set up mobile nodes?
Hi all, I get an error which I have enclosed when I try setting up nodes in wireless scenarios. I have tried a lot of different things as suggested by other tutorials but get the same error everytime. When I delete the lines defining the nodes from the code, there are no error messages. Code that I am using is also enclosed. Please help me out at this, I really need help quickly. Faraz

Hi Faraz
Can you please write the code in your email, because ns user mailing list drops
all the attachments.

[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

Re: [ns] segmentation fault
Hi Dasari Mallikarjuna Look at this link to resolve the problem of segmentation fault. http://article.gmane.org/gmane.network.simulator.isi/2766/match=segmentation+fault Besides this, after making any changes in c++ code of ns2, do this: make clean make sudo make install Regards Mubashir Lip6, UPMC, Paris, France. 2009/1/8 dasari mallikarjuna dnm...@yahoo.com I am using programs written by Lavina Jain et al (in ns-2). I have made some changes to the program and tried to run it.It is giving Segmentation fault. I removed the changes and again used make, still the problem is persisting. I had to re-install theoperating system (fedora linux) to remove the erro. What could be the problem? -- Mubashir Husain Rehmani
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
