[ns] DSR in wired-cum-wireless scenario

[Chih-Fan Hsin <chsin@engin.umich.edu>]

Dear ns users,

According to NS manual Chap 16.2.1, it seems that DSR can be used in a
wire-cum-wireless scenario.
I tried to run wireless3.tcl(mobile IP) in Marc Greis's Tutorial and
changed DSDV to DSR. However, an error message comes up. I attached it below.
Could anyone give me a hand?
