"cross_aodv_test.tcl" : Unknown file.
You can attach the file as cross_aodv_test.tcl.txt
* Attachments : The paper clip tool in the 'Advanced Editor'.

The default `Csma/Ca' examples :
csma-ca.tcl, (csma.tcl), mac-test.tcl, miptest.tcl, mtp.tcl, snoop.tcl
* See "all_tcl-examples-2.tar.gz" ( ~2,000 ns2 simulation files, 41.8 MB )
https://drive.google.com/file/d/0B7S...ew?usp=sharing

All the above default csma examples are supposed to run with a default unmodified 'ns'.
Not necessarily with a modified 'ns' ('ns-<new-name>').
? Did you do any changes to your ns-2.xx ? Which ns2 version is it about ?
