I got this error when i tried running my nam simulation:
tracefile events not sorted by time.
What could be wrong?
below is the tcl script

You
should have pasted more information from the simulation script file. I think
the destination of the node is "beyond" your topography grid size. Check that.
Good luck.

hello,
i got this error when i tried simulating a mobile ip scenario in ns.though the
simulation runs,but runs just for 9.6s instead of 1010s set in
script.
