Dear Liceven,
While I cant give you step-by-step instruction on how to solve your problem.
But here is the idea. If you were to go to
ns-allinone2.xx/ns2.xx/mobile/antenna.cc file you will see the function:
Antenna::Antenna()
{
X_ = 0; Y_= 0; Z_= 0;
bind("X_", &X_);
bind("Y_", &Y_);
bind("Z_", &Z_);
}
Basically this constructors binds the X_ variable in the TCL file with the X_
in the C++ file. If you were to add say:
cout << "X position" << X_ << endl;
cout << "Y position" << Y_ << endl;
cout << "Z position" << Z_ << endl;
after bind("Z_", &Z_); but before }. And then run the "make clean" and "make"
command at the Linux command terminal in the ns-allinone2.xx/ns2.xx/ prompt
area. Once thats done, if you were to run your .tcl file, you will see an
output, which specifies the position of your node in X, Y, Z coordinate.
The glitch with this approach is that it shows you the coordinates for time
0.0, mean just at the start of the simulation.
For your problem, YOU need to find the .cc file which is responsible for
changing the X, Y, Z coordinates. Once you locate that .cc file, then locate
the function which is changing the value of X, Y, Z, and then you can add the
above cout lines at the end of that function.
This way, when you run the simulation, you will get live time output of the X,
Y, Z coordinates. If you know C++ half-decent, then I think it will not take
you more than 2-5 hours to locate the function and find the solution of your
problem.
PLEASE ONCE YOU SOLVE YOUR PROBLEM, DO SHARE YOUR SOLUTION WITH OTHERS ON THE
NS MAILING LIST.
Kind Regards

Subject: [ns] How to get a mobile node's current position
Hello,everyone:
I want to simulate a wireless scenario with two access points and a
mobile node. This mobile node moves randomly, the question is how to
calculate it's position like(x=?,y=?,z=0) at any given time. It could be
better if you could give me an example. Of course, any suggestion is
welcome.
Regards.
Liceven
