B.A.T.M.A.N. (Better Approach To Mobile Adhoc Networking)
B.A.T.M.A.N. does have elements of classical routing protocols: It detects other B.A.T.M.A.N. nodes and finds the best way (route) to these. It also keeps track of new nodes and informs its neighbours about their existence.
B.A.T.M.A.N counts the originator-messages received and logs which neighbour the message came in through.
Like distance-vector protocols, but unlike link-state protocols, B.A.T.M.A.N does not try to determine the whole way, but, by using the originator-messages, only the package’s first step in the right direction. The data is handed over to the next neighbour in that direction, who in turn uses the same mechanism. This process is repeated until the data reaches its destination.
