You can use 802.11s (mesh point) interfaces for batman-adv when you set mesh_fwding to 0. But most people use IBSS (adhoc) at the moment for batman-adv. It doesn't really care that much about the underlying interface. It just has to be ethernet compatible and support some basic features like broadcast. So you could even run infrastructure mode (AP+Sta) with batman-adv. But it doesn't make a lot of sense in most situations :) The B.A.T.M.A.N. V algorithm implementation has some extra requirements. It must be able to get the expected throughput towards a different device from=20cfg80211. You can check if the driver supports this by checking `iw dev wlan0 station dump` and searching for "expected throughput:". The Mpbs value should represent the reality (and not be complete bogus). The biggest problems here are driver/hw bugs. Even the ath9k hardware (which works quite well) has its fair share of problems. > there are two wifi network card , and i thought Rt2070 will support > Batman-adv . >=20 > Because Rt2070 will support interface modes ( mesh point ) , and > RTL8188CUS can't support interface modes based mesh point . Both advertise support for IBSS. So you can (in theory) use adhoc on both devices and run batman-adv on top of these adhoc interfaces. But you may end up with driver problems (at least I already had problems with Realtek and Ralink hardware). Maybe someone else here already tested these two chips and tell us more about them.
