[ns] can't read ragent_: no such variable

[Luís Barreto]

Hi,

I'm using DSR routing protocol in a wired-cum-wireless simulation and
am having the following problem:
can't read ragent_: no such variable
while executing
subst $[subst $var

Could you please tell how to set up this variable and solve this
problem?

I got this problem for a long time and couldn't solve it. I´ve
searched and no one says the solution

Thanks for your help.

[ns] Reply to ragent_ question

[Mubashir Rehmani]

Hello

You can declare ragent_ for instance in your tcl script like this:

set ragent_($i) [$node_($i) set ragent_]
$ns at $var $ragent_($i) Myfunction

Then in your tcl script you can also have the ragent_ reference like this:

puts mubashir $ragent_(0)
puts mubashir $ragent_(1)

And you can have access to this ragent_ in either you AODV.cc or DSR.cc
protocol by utilizing it by defining Myfunction in command

AODV::command(int argc, const char*const* argv) {

if(strncasecmp(argv[1], Myfunction, 2) == 0) {
//do what ever you want
}
  return TCL_OK;
}

Hope it helps

Regards

Re: [ns] Fw: how i can run new mac protocol in ns

[Jalaluddin Qureshi]

Dear Reza,Create a new folder in the ns2.xx folder and place your .cc and .h 
file in that folder.Go to the makefile, and add this (folder name)/(your .cc 
file name, with .o postfix)\  after OBJ_CC = \ but before $(OBJ_STL).Once 
thats done, save your makefile. And run  the command make clean, then make 
depend, and finally make.If no error are reported after the make command, 
then this means, your .cc and .h files have no error. And therefore a .o file 
will be created in your folder after you have run make command. Your new mac 
protocol is now ready to be used.
