Hi,
This is the meat of what I am asking - I am wondering what context is it proper to use BATMAN, and the reason I am confused about it is that I see most (all ?) of the freifunk networks using OLSR.
first of all I have to say not all Freifunk networks use OLSR but I think it is fair to say many of them do and here is why:
a) These networks use the "standard" freifunk firmware that you can find here: http://downloads.berlin.freifunk.net/ - this firmware has OLSR built-in (the maintainer is/was an olsrd.org developer).
b) Many networks were using olsrd.org as protocol before batman became stable, hence they face upgrade issues (in a decentral environment).
c) These networks are community driven networks and somewhat slow to embrace change. A whole network requires a lot of maintenance - you don't want to fiddle with the protocol every week (although quite some experimented with batman - Weimar comes to mind).
d) None of us is actively trying to "lobby" batman into the Freifunk networks. If they have questions they can contact us (some do) but other than that ..
In general we see a strong adoption in new networks (no dependency issues there) and recently people are quite interested in layer 2 which gives you roaming/meshwide DHCP/etc.
So, I can understand you - Freifunk initiated an innovation that it does not use. Our biggest user groups are outside of Freifunk - funny. :)
And as an aside, I am curious, if any freifunk networks are using BATMAN, what routing metric do they use ?
The TQ based algorithm.
