Hi,

Please keep in mind that you will experience packet loss. After 2-3 hops only 
a few packets get rebroacasted. 
In other words: B.A.T.M.A.N. already has Fish-eye because only the direct 
neighbours get most of the packets. With each hop the numbers of retramsitted 
packets decreases due to packet loss.

batman-experimental is a testbed for future improvements of the B.A.T.M.A.N. 
protocol. Here we experiment with certain ideas. Do not use it in a 
production environment.

batman is the implemantation of B.A.T.M.A.N. on layer 3. It is pretty stable 
and usable.

batman-advanced is B.A.T.M.A.N.on layer 2. Its code is based on batman but it 
is fairly new. Expect heavy developement in this branch.

Regards,
Marek
