I am using batman (2012) for a wireless network where we have a polling based or star type network /mac topology. Similar to wifi PCF but proprietary instead of DCF.
I have noticed that if i have just 2 nodes and one node sends broadcast data (say video 192.168.1.255) that the other batman node will turn around and also re-transmit the same data back out. So basically i see twice the data on the over the air network which the originating batman node drops since it originated from him.
Two Questions: 1) given that there are only two nodes , does BATMAN adv have a way to realize there aren't other nodes wanting to receive the broadcast and since the source of the broadcast is the only other batman node it shouldn't transmit it again?
2) For cases of where batman is used in a more structured network instead of a true mesh/adhoc topology, are there parameters that could be used to limit re-broadcasting data received via wlan interface?
