make-lan is used to create wired lans and doesnot support creation of
wireless lan. it might be a good idea to extend make-lan or have something
like make-wirelesslan as a one step method of creating and setting up a
wireless topology. (to be added to our to-do list)

for now, you could make a wireless lan by creating mobilenodes as in the
example script wireless.tcl or wireless-test.tcl in ns/tcl/ex.
