Hello,
We have finally deployed a WMN testbed on our campus , currently running
roofnet. However I would like to run BATMAN as the underlying routing
protocol. Could you help me out with deploying and testing BATMAN on the
nodes.
Further since our nodes have two radio we are looking at taking
advantage of the same. Any pointers from a coding perspective to tackle
this would be great as I am hoping to publish the same.
Also does Batman advanced operate in Monitor mode?
Thanks

Hi,
Further since our nodes have two radio we are looking
at taking
advantage of the same. Any pointers from a coding perspective to tackle
this would be great as I am hoping to publish the same.
what do you mean ? You want to know where in the code batman handles multiple
radio interfaces ?
Also does Batman advanced operate in Monitor mode?
Unlike MIT roofnet the batman kernel module does not operate inside of the wifi
driver. Batman does not care about the underlying driver / mode / etc - it can
run on anything that transmits Ethernet packets.

Now if Batman would handle the same, that would be nice.

Right, that is still on open point on my ToDo. I'd like to automate that if
possible but did not have a good idea how to do that.
Kartik: Any idea how roofnet is doing it ? Config ?

Let's say a packet comes from node A interface ath0 of node B, and
there is a route on node B for the packet to go to node C, route which
use the same interface ath0. In this case, you might want to add a
cost to hop over the same wireless interface.

Hopping over the same radio means:
* dividing the bandwidth by two at each hop and
* choosing the worst radio link of your two neighboors

Ok, good idea. I quickly made a patch:

Feel free to test it. :-)

Yes. I have just started going through the code so wondering how
multiple interfaces are handled.

At the Wireless Battle Mesh of Paris, the author of
Babel wrote a
quick patch to add some cost to hop over the same wifi
interface.
Here is a summary:
We are trying to service the internet access through a regular
infrastructure mode via an access point connected to the wired interface
on the node. Apart from that each node has 2 wireless interfaces that
can be used to reduce intra hop interference. So wanted to know if
BATMAN can take advantage of two radio on each node to improve
throughput.

I tried Batman at the WBM to see if it was finding the fastest route
in terms of bandwidth, and it was not doing it. So Batman will
continue to hop on the same channel, even if another route is faster
in terms of bandwidth.

Just to clarify. Every node has 2 radios. One on 11a and the other 11b.
Does batman take advantage of this like WCETT/iAware/MIC ....
Thanks
