Ideally, you have BATMAN on the AP as well as the STA. So you never do
STA->AP->STA hops between BATMAN nodes, you only do a STA->AP BATMAN
hop followed by a AP->STA BATMAN hop. Performing two BATMAN hops means
BATMAN knows the transmit quality of each of the two wireless hop, not
the combined transmit quality of the STA->AP->STA path. So BATMAN
running on the AP can then decide if it makes sense to take a
There is code to enforce this, i.e. blocking STA->AP->STA transfers,
in the development tree and it has been push upstream to be included
in the mainline kernel.
