[ns] AODV local repair

[Nadilma Nunes]

Hi,

i'm new to ns2, i'm from brazil and im doing a research about the aodv
peformance.

i'm trying to change the aodv code.cc to make two changes:
1- disable the "local repair". So, when a route changes, it would be
rebuilded from the source.

2- do the opposite. Change the aodv.cc to always make the "local repair" for
building the route when the route changes.

But i'm get no success on what i've been trying. So i'd like to ask ur help.

Any suggestions?

[thanks, and sorry about my english]

[ns] request for help about tracegraph

[An Feng]

Hello,

I tried to load a trace file into tracegraph, but the software reject to
accept that. And I then use trace converter to modify that trace file, and
tried to load again. But still the same thing happened. Can any one help me
to find out why this kind of thing happen?

As the tracefile is 30M large, I just attach the source file, and please set
"-nn 10", the full command is "ns final5.tcl -nn 10", I use ns-2.29 to
compile that.

Thank you for your kind help.

[ns] Retrieve C++ variable in TCL code‏

[Johan Uijen]

Hi,
 
I am using ns 2.33 on a solaris/intel machine. In the ns2 TCL script I want to 
use a variable defined in C++. The variable is used for looping control as 
follows:
 
while {$x < 16.0} {
...
for {set y 1.0} {$y < $ns at $x "$sipalice getSize"} {set y [expr 
(0.5+$y)]} {
  ...
 }
 ...
}
 
The statement $ns at $x "$sipalice getSize" returns now some weird integerid. 
The command getSize is defined here:
...
} else if (!strcmp(argv[1], "getSize")){ 
 Tcl& tcl = Tcl::instance();
 sprintf(tcl.buffer(),"%d",SIPSingleton::getInstance()->getSize()); 
 tcl.result(tcl.buffer());
 return(TCL_OK);
}
...
I think the tcl.result is overwritten by the Scheduler::command(..) function...
Is it in in any way possible to return a variable to the tcl script when the 
scheduler is started? I know it is possible without timing (without the "$ns at 
x" part), but I have to use the timing otherwise statements are executed too 
early.
 
Regards,
 
Jo
