[B.A.T.M.A.N.] Multipath-Routing BATMAN-ADV

["Daniel Roßbach"]

Hello,

I try to research some possibilities to implement multipath-routing (MPR) to BATMAN Advanced. There are two different ways: 
1. one-channel-MPR and 2. multi-channel-MPR.
To the first: 
The idea is to use two paths through the mesh and to avoid crossed. I have build a simple model to show that it make sense. The model shows that it can take 67% of the time that needs BATMAN with a single path. I still implemented it into userspace of revision 1060. The next step is to proof, that it works...or that it doesn't work...!

To the second:
The idea is the use of multi paths with multi interfaces. Packets can be transmitted over two different ways without any interference problems. At the moment I'm analyzing the problems and the requirements for this. 

The better way is of course the second one. The advantage of using one channel is that there is just one wireless interface needed.

that sounds very cool ! Let me tell you that many people try but it seems not 
that easy. :-)

Can I see that model somewhere ?
How far are you with your implementation ? Is there anything we can see ? May 
be you should explain your idea in more detail in order to get feedback from 
experienced mesh people before you spend too much time walking in the wrong 
direction. Some ideas work very well on the paper but have severe 
difficulties in real life deployments.

Nice - let us know as soon as you found something.
