# B.A.T.M.A.N. in Berlin¶

The first experimental setups using the B.A.T.M.A.N. routing protocol daemon have actually started just in parallel with the advent of the first available implementation. This was also due to the fact that in 2005 most of the dedicated B.A.T.M.A.N. developers lived in Berlin and always wanted to develop a protocol out of practical experience instead of theory and paper work.

Since then the number of nodes running B.A.T.M.A.N. and OLSR in parallel have constantly grown and the first mesh-node administrators have now started to run a B.A.T.M.A.N.-only stack.

Today, the routing table typically lists entries to about 50 other B.A.T.M.A.N. interfaces. However, the exact number of mesh-nodes participating in the Berlin-B.A.T.M.A.N. Cloud is unclear since (not like OLSR) the protocol only maintains entries and routes to nodes which are in-fact reachable. Some B.A.T.M.A.N. might just be to much hops away in order to establish a reasonable connection.

The following links provide a collection to miscellaneous insides to various Berlin-B.A.T.M.A.N. setups.
