Hello Carlo,

batman-adv-kernelland is currently not integrated in madwifi (this is just another idea on our TODO list). You only need to compile the batman-adv-kernelland/batman-core/ directory against your kernel. This gives you the batman-adv-core.ko module which you can insmod and is independent from madwifi (and any other driver).

Best Regards, Simon

Hi Marek, thank you for your quick reply....

I would like to compile the module...I don't need the complete openwrt integration... I would like to see and study your (you all) work on kernel space.....

At the moment I have already build a custom openwrt firmware....but from what I understand I need to patch the madwifi driver to support the new feature and recompile the driver....then I can build the batman module... I need only some hint on what steps to take in order to compile the module...I doesn't seem so difficult but i wanna follow the right steps...

Obviously if I don't waste your time.....

Hi,

...

How can I compile the stuff https://dev.open-mesh.net/svn/batman/trunk/batman-adv-kernelland/ into openwrt...I would like to try the layer 2 version on my fonera router....

currently I'm working on the batman openwrt integration. It is a bit tricky and I'm not 100% finished yet. It will be included in the latest kamikaze trunk. Either you wait some more days or I send you my current status.

...

I don't understand if I have to integrate it in a package inside the menuconfig or I can build everything off from the standard configuration...

You can't use the standard configuration.

Hello Carlo,

thanks for pointing that out, i cleaned the directory up and wrote a little README. :) The kernel module might still be a little unstable, but have fun testing.

Best Regards Simon

Hi Simon, thank you very much...much easier then I tought....probably I was wrong because of the madwifi directories into the svn repository.... Ok tonight I will try....

Thank you very much again...

Hi All, thanks again....

I managed to cross compile correctly for my atheros target...really easier than I tought...

Stay tuned for tests report....as soon as possible I will start to do some test...

Do you have some stub for testing???

Regards, Carlo

thank you for doing so. I hope it is more understandable now. :-)

Please give us feedback about your results - even the bad news. ;-)

Another thing - think of this as quasi-asynchronous links, i.e. B can talk to A on both interfaces (call them int1 and int2), but only chooses int1, and A does the opposite, chooses the other (int2) to talk back to B. If B has to talk to both A and C at the same time and can see A and C on both int1 and int2 then it will choose int1 to talk to A and int2 to talk to C.

Maybe it makes sense now....

P.S. or maybe I'm just missing something

Ok. Here is something batman doesn't provision for - dual-interface setup where you want to create a duplex link (tx on one and rx on another). Duplex link to one other node is simple (and has to be done manually), but how would we go about creating a duplex link to 2 or more nodes? Or one simplex link to downstream node and one simplex link to upstream node? Example:

A = B C duplex link (for example I need to talk from B to A fast and I use both interfaces to talk to A) A - B - C simplex links (I use one interface to talk to A and one to talk to B) A = B/B = C duplex links for all links (I talk to both A and C duplex, but not at the same time of course)

How do we do this with batman easily and dynamically (without having to manually mess around with routing tables etc)?

Hi Predrag,

BATMAN does not really support that for multihop mesh networks. If you want this behavior only for single hop connections you can cheat with batmand-exp using the options: --asymmetric-weight and the interface specific option /c

A smaller /c value (than the default) will apply a penalty to the detected link transmit quality of an interface and the --asymmetric-weight switch can then be used to tell the algorithm to be more reluctant to use links with a bad transmit quality.

I successfully tested this in a simple wired two-node setup each with two interfaces as illustrated below. Afterwards batman did set up the routing table that a ping between node A and node B always chooses the upper link from A to B and the lower link from B to A.

node A node B eth0 -------------> eth0 eth1 <------------- eth1

therefore I started on node A: batmand --asymmetric-weight 2 eth0 /c 100 eth1 /c 50

and on node B: batmand --asymmetric-weight 2 eth0 /c 50 eth1 /c 100

But be aware, that this will change the default behavior of batman and may have negative side effects on the overall path detection in you mesh.

ciao, axel

Has anyone thought about this "problem" recently?

To simplify - 3 routers, 2 adapters each, how do we establish duplex links between each of those by using batman alone?
