Hi Ashwin,

Gesendet: Donnerstag, 31. Januar 2013 um 17:04 Uhr Von: "Ashwin Chauhan" ashwin.chauhan05@gmail.com An: "b.a.t.m.a.n" b.a.t.m.a.n@lists.open-mesh.org Betreff: [B.A.T.M.A.N.] Help and Suggestions Please! :)

I'm a Computer Science Final Year Undergraduate student. We are a group of Four students and are wanting to do our final group project on B.A.T.M.A.N protocol. Can you help us with the simulating a simple sample network.

For simulating various network topologies with batman-adv, kvm is quite often used. Have a look at: http://www.open-mesh.org/projects/open-mesh/wiki/Emulation

Also I was thinking, If instead of Broadcasting the OGM Packets every time into the network, we could broadcast them the first time a node joins the network and then just Multicast the OGM packets to its one-hop neighbours from the next time. So that their immediate nodes are still informed about the existence of the node in the network. This way we can reduce the unnecessary flooding of packets. Also when a node moves out of the network its immediate node would know about it much faster and can then broadcast it to other nodes.

B / \ A D \ / C

If, let's say D wants to forward packets to A and sometimes the path via B and sometimes the one via C is better due to link quality changes between A-B and A-C. How is D supposed to learn about the better route if link quality changes on A-B and A-C do not propagate any further?

Trying to do our final year project in this area. Also can someone suggest us some ideas to work upon as our final year Project. :)

There's a list of rough ideas from the last Google Summer of Codes: http://wiki.freifunk.net/Ideas#batman-adv

Cheers, Linus
