Re: [ns] Agent creation problem
Dear loukman with thanks from Nicholas, I suggest you that modify makefile.in instead of makefile, according to Nicholas help. I attached you a .pdf file that is so usefull in creating a new agent and adding it to in NS. please read the needed changes part of it that explains how to add your new agent to ns. be lucky. your sincerely: Fahimeh From: nicholas mbonimpa nmboni...@gmail.com To: Fahimeh Akbari fahimeh...@yahoo.com Cc: Loukman NAJDI loukman.na...@utt.fr; ns-users@ISI.EDU ns-users@isi.edu Sent: Tuesday, August 16, 2011 3:51 PM Subject: Re: [ns] Agent creation problem Hi there, As Fahimeh said, you've most probably not gone through all the necessary steps of adding a new agent. Most importantly, you need to modify the Makefile in the ns-2.34 (or your version of ns-2) directory and include tcp-Fack.o, then run make again to create an executable for your agent. I hope that will help.

Re: [ns] Scheduler error - NULL handler
Hi I had this problem in my simulations. I have been send a data packet to a NULL target (my sender node was not attached to my destination node). see scheduler.cc file in your ns directory. this error is created from there. search this error text, and see what null pointer did you used in your simmulation. be lucky: Fahimeh From: Aslinda Hassan aslinda.has...@mun.ca To: ns-users@ISI.EDU Sent: Tuesday, August 16, 2011 5:33 PM Subject: [ns] Scheduler error - NULL handler.h Hi everyone. Currently, I'm implementing a new routing protocol for ad hoc network, and I have managed to compile it without any errors. Unfortunately, when I tried to test my protocol, I received the following error: Scheduler: attempt to schedule an event with a NULL handler. Don't do that . I was wondering if anyone have any experience solving this problem or at least give some advice on where to look at. I have goodgled this problem on the Internet, and so far I found a number of people having the same problem but without any solution. Any help regarding this matter is highly appreciated.

[ns] how receive CBR packets at my own agent????
Hi
I want to receive every CBR packets in my own agent and after extracting some
data from that, forward it to it's destination.
So in my agent constructor definition, I used from following code:
/**/
SBC2::SBC2() : Agent(PT_CBR) {
dup_flag_=0;
// set_pkttype(PT_CBR);
puts(SBC2::SBC2\n);
}
/**/
but It doesn't work and doesn't receive any packet. I tested PT_UDP and
PT_RTP too. what I must to do. Please help me. I have so little time.

[ns] Fw: SIP wireless node problem!
Dear All, I am trying to simulate SIP protocol in a Wired-cum-Wireless and MobileIP network. After compiled the Rui prior SIP patch successfully in ns-2.27, I have tried a simple wired network example and it worked. However, when I introduce some wireless nodes running SIP on it and connected via a base station with wired network in the simulation. I got errors like: Segmentation Fault! I did not meet this error in wired network, so I think maybe because of wireless nodes in this simulation or some undefined class in some part of this simulation. I have no idea which part of the script lead to this error. What do you guys think of this problem? Can you suggest me where I should go to check and fix this problem in NS-2? It's so important for me. please help me. with thanks: Fahimeh Akbari fahimeh...@yahoo.com
