The Better Approach To Mobile Adhoc Networking, or B.A.T.M.A.N., is a routing protocol which is currently under development by the “Freifunk”-Community.
B.A.T.M.A.N.'s crucial point is the decentralization of the knowledge about the best route through the network - no single node has all the data. Using this technique, the need for spreading information concerning network changes to every node in the network becomes superfluous. The individual node only saves information about the “direction” it received data from and sends its data accordingly. Hereby the data gets passed on from node to node and packets get individual, dynamically created routes. A network of collective intelligence is created.
