I am trying to simulate a 3D simulation. ns2 has all mobile nodes and access points depicted graphically via the use of x,y, and z coordinates, however I am not sure how to simulate these correctly. I used the FreeSpace radio-propagation model, which doesn't complain if you give your nodes a non-zero z coordinate, but then I got unexpected results and again looked through my code.
I then realized that every simulation example I had seen has "$topo load_flatgrid $opt(x) $opt(y)". Is there a way to load a 3D grid, rather than a 2D grid? If so, how is that done?
