[ns] BlueHoc: what version of ns-2? ns-2.1b7a or ns2.1b8a?

[pietro.luigi.c@alice.it]

Hi to everyone,
I try to install BlueHoc on an installed version of ns-2.1b8a.
Now when I apply patch
patch -p0 -b <bt_patch

I discover it refers to ns-2.1b7a...but in the BlueHoc Official Site
BlueHoc is referred to ns-2.1b8a!

Some one know the right patch or the right way to install BlueHoc without many problems??

Now someone can says what version I should use...

Thank u in advance,
Pietro
