Hello Max,

BATMAN is a routing daemon, a userspace program modifying the routing
table on each node to build up the mesh network. It sends UDP packets
to exchange information. This is very different from 802.11s, which is 
building the mesh on the Link Layer. In 802.11s, routing information
is exchanged via WiFi management frames, and it is implemented in the 
wifi driver.

Depending on your view, BATMAN is also a routing algorithm. It could
also be implemented directly on the Link Layer. We have implemented the
algorithm in batman-advanced on the Ethernet, to use Ethernet Frames 
to exchange information and route (or better switch) Frames on our own. 
You get a virtual interface, and can use the mesh network like a big switch.

Still, this has little to do with 802.11s. I guess its possible to
implement the BATMAN algorithm into the 802.11s framework as well.
If you want to do so, i recommend to go with Luis suggestion and
contribute some code to mac80211. You should know that this would require 
serious efforts for you, it is not done with "providing Luis some 
information".

However, it is not even needed to implement BATMAN in the wifi driver. It can
run very well ON TOP of the otus wifi driver, as it runs on any other wifi
driver. The only requirement is that the driver supports AdHoc Mode, and 
according to the announcement that is the case.

best regards,
	Simon
