[B.A.T.M.A.N.] Multiple radios to improve throughput

Elektra,

Thank you for pointing out in May 08 that most embedded boards do not have enough CPU power to saturate the capacity of single radio link. I was experimenting Batman in a straight line, three node configuration with the middle node having two radios so it doesn't have to switch between node 1 and node 3. My configuration is as follows:

node 1 node 2 node 3 ------ ------ ------ ath0 <--ch 1--> ath0 ath1 <--ch 11-> ath0

When I ran iperf between node 1 and 3, I did not see any throughput improvements with either one or two radios in node 2. I even stopped Batman and manually setup the routes and the performance remains the same. However, when I upgrade node 2 from a 200MHz CPU board to a 500MHz CPU board, the bandwidth went up 50%. So thanks again for pointing out my bottleneck:)

Lastly, can someone suggest some embedded boards fast enough to push wifi radios to its limits?

Thanks, Shane
