NS2 and TORA Routing Protocol

Hi mates

I have a strange problem regarding network. I just want to ask that anyone who has run TORA routing protocol successfully can please help me.

I have problem that has been really bothering my work for sometime.
I also want to execute the TORA protocol in ns2 and it really gives me headache as it gives me some errors.
I tried creating so many attempts and tested them to run on other protocols namely DSR and AODV but when I try to use TORA, the same scripts and attempts give me errors.
I also know that there must be a modification to do on the protocol itself or the ns2.

Below provided is the Error Code:

Hi I wanted to TORA ins ns-2.32 and made necessary modifications in tora.cc and tora.h . There is no error when I run a tcl script with $val(rp) TORA. However I see in NAM and in tracegrapg that there is no packets being generated. Is it necessary to make any changes in any other cc files or header? Or unlike in AODV and DSR is there any other parameters to be :specified in tcl script ? Some posts had suggested using

set tcp [new Agent/TCP/Newreno]

but this too didn't work.

Please suggest how to fix it.
I would be glad if someone could post a small working script.
I appreciate your help. Thanks

Hi on everyone. I have the ns2 2.34 version and I am having the same problems with Tora protocol. I have made all the changes that you have proposed but I am still having problems.
Is it better to use adhocRouting or rp when you set up the protocol? What is the difference between set val(rp) from set opt(rp)? Please tell me what to do.


Regards,

flogeros

Hi Zachary. I am facing the same problem with the tora protocol. Could ou please write down step by step what changes should I made in order to work properly the tora protocol?

Regards,

Flogeros

Hi Bathena. I am facing the same problem with the tora protocol. Could ou please write down step by step what changes should I made in order to work properly the tora protocol?

Or unlike in AODV and DSR is there any other parameters to be :specified in tcl script ? Some posts had suggested using

set tcp [new Agent/TCP/Newreno]

but this too didn't work.

Please suggest how to fix it.
I would be glad if someone could post a small working script.
I appreciate your help. Thanks

Dear Zachary first of all I would like to thank for your help. The script that you write me is ready for use? Because I have saved in a tcl format and I run, but I've got again errors. Please tell me what to do next because I am lost.


Kind regards,

flogeros

Well, i guess you should give it a try, if it gives you an error, post back regarding what you getting error... :thumbup1:

Dear Zachary I am sending you the error that I am getting back.
invalid command name "Agent/rtProto/TORA"
while executing
"Agent/rtProto/TORA instproc init args {
puts "DOWN HERE"
$self next $args
}"
(file "tora_s.tcl" line 15)
Can I send an email regarding the adhoc protocols? My email is korgani@hotmail.com

Hello.
I am trying to simulate TORA routing protocol. Can you help me please?
I tried to change files tora.cc and tora.h.
I added to tora.cc lines:

else if (strcmp(argv[1], "port-dmux") == 0) {
dmux_ = (PortClassifier*)TclObject::lookup(argv[2]);
if (dmux_ == 0) {
fprintf(stderr, "%s: %s lookup of %s failed\n",
__FILE__,
argv[1],
argv[2]);
printf("%s lookup of %s failed\n",
argv[1],
argv[2]);
return TCL_ERROR;
}
return TCL_OK;
}

and to tora.h i added this

#include <classifier/classifier-port.h>
protected:
PortClassifier *dmux_;



Unfortunately it doesn t help me. I tried to run following tora.tcl file

When I run a file, which was posted by Zachary I get same errors as user flogeros wrote.
I am using ns 2.34. Can anyone help me please? Thanks

Hey all,
I have made necessary changes in the tora.cc and tora.h flles, but when i m trying to recompile ns-2.34 using make, i m getting following errors....

tora/tora.cc:10: error: expected constructor, destructor, or type conversion before ‘(’ token
tora/tora.cc: In member function ‘virtual int toraAgent::command(int, const char* const*)’:
tora/tora.cc:92: error: cannot convert ‘_IO_FILE*’ to ‘const char*’ for argument ‘1’ to ‘int printf(const char*, ...)’
tora/tora.cc: At global scope:
tora/tora.cc:193: error: expected unqualified-id before ‘else’
tora/tora.cc:198: error: expected unqualified-id before ‘else’
make: *** [tora/tora.o] Error 1




Anybody plz post how to fix them, any type of help would be appreciated...

thanks in advance..

Hey all,

I executed my simulation using TORA on ns-2.34 by doing modifications in .cc and .h files as described above....
bt their is one problem that has occuered is that the .tr file is not created completely, it is getting hanged somewhere at time 4.0666, while my simulation is for time units 125.

if anybody has any soluton for that plzz help me....

I think that, set_sql_trace_in_session will write a trace file to to UDUMP destination. You will then need to run tkprof to put it in a readable form.
ie,
tkprof ...\udump\oraxxx.trc newfilename.txt explain=username/password@sid . If you are tracing a query that runs in the context of a Job( I presume you mean DBMS_JOB), then the sql trace is generated by the executing job_queue_process and not the shadow process of the Sqlplus session.
In this case it will be created in background_dump_dest and NOT in user_dump_dest. The process name will start with "j....". Read more here.
