It sends UDP packets to exchange information. This is very different from 802.11s, which is=20 building the mesh on the Link Layer. In 802.11s, routing information is exchanged via WiFi management frames, and it is implemented in the=20 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=20 to exchange information and route (or better switch) Frames on our own.=20 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= =20 serious efforts for you, it is not done with "providing Luis some=20 information". However, it is not even needed to implement BATMAN in the wifi driver. It c= an 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=20 according to the announcement that is the case. best regards, Simon On Thu, Oct 23, 2008 at 09:52:06PM +0200, M.
