Hi,

thanks for submitting your work. I published it on our website so that others 
can find it: https://www.open-mesh.net/batman/patches

By the way: Using the TTL as basis for a hop metric is ambiguous and may lead 
to errors. By doing so you assume that every host uses the same start TTL and 
every hop decreases it in the same way. The B.A.T.M.A.N. protocol does not 
demand or enforce this behaviour. 
On the other hand the hop count does not reflect the quality of a path. May be 
it would be a better approach to calculate the link quality into the metric 
so that hop based protocols can do a better decission.

Regards,
Marek
