I just found out /(the hard way) that using network coding (batman-adv 2013.4) that i have a massive, unbelievable bandwidth loss if i have more than one hop to the destination
I tested this in a real scenario with 11 nodes as well as 3 nodes in a house with 3 floors and having one per each floor.
Here is the example with 3 nodes
A <------ B -----> C
From node B to iperf reports me 15 mbit From node B to node C iperf reports me 9 mbit
Then, from node C to node A i get values bellow 1 mbit such as 647kbits or less. More than 3 nodes is to forget.
uci set batman-adv.bat0.network_coding=0 disables nc and solved the problem which brought the network bandwidth to a more realistic and mathematical acceptable bandwidth level.
Is this finding known by others ?
