Yes, you can at least use the X_ and Y_ coordinates of the mobile nodes to find the difference between them and calculate distance. Note that Z_ is useless, as ns simulation is only 2 dimentional. You can see how to access these in the ns documentation. Just search in the mannual. > 2- which parts or files compute "throughput , packet loss and delay " > in wireless simulations? Throughput: u can use "loss monitor" this section "http://www.isi.edu/nsnam/ns/tutorial/index.html"; from marc greis's tutorial should give you a clue. The rest, (packet loss and delay): u can at least can calculate them by analysing the trace file using some script language like "awk, perl...". For these, u need to understand a little bit about the trace file pattern.
