Hi all I am experimenting some path hopping in my tests using batman-adv. Was wondering if and where metric information are shared among batman nodes (again, with batman-adv) as I did not find any useful infos sniffing packets with wireshark patched.
The command batctl l shows (with log level 8)
$ batctl l [ 9462] Changing route towards: 00:0b:6b:2f:53:09 (now via 00:0b:6b:34:88:94 - was via 00:0c:42:2c:d8:fc) [ 9525] Changing route towards: 00:0b:6b:2f:53:09 (now via 00:0c:42:2c:d8:fc - was via 00:0b:6b:34:88:94) [ 9560] Changing route towards: 00:0b:6b:2f:53:09 (now via 00:0b:6b:34:88:94 - was via 00:0c:42:2c:d8:fc)
But no info about actual metric when a route is changed.
Thanks.

I'm not entirely sure what you expect to find or what is missing. If you want to understand the batman protocol you might want to start with some of our recorded talks. If you want to use wireshark to analyze the traffic be sure to have the batman dissectors installed (or use batctl td). If you want routing debug information from the module use debug level 12 (batman [4] + routes [8]).
Hope that helps, Marek
Hi,
I was just looking for a name: the name of the metric (is that ETX?) that is used in batman-adv. Actually i did not find any useful info in old messages on the list.
Thanks.

Hi,
I was just looking for a name: the name of the metric (is that ETX?) that is used in batman-adv. Actually i did not find any useful info in old messages on the list.
The metric used by batman-adv is called TQ (Transmission Quality) and expresses the sending link quality from the current node all the way down to the destination.
There is a document explaining the main ideas behind the algorithm used by batman-adv that you can download here: http://gitorious.org/batman-adv-doc
Disclaimer: This paper is not an official document / complete / meant to be a RFC / etc. Use it at your own risk. ;)

Many thanks for your reply. That was exactly what I was looking for. Why don't you add a pointer in batman-adv doc page? It could be useful to many I think, even if it is pre-alpha :)

Experience have shown that as soon as we put a document on the website which is not carefully worded / did not undergo a detailed review process / etc, all fanboys will leave their hiding grounds to begin a flame war on mailing lists / forums / private mails causing damage that takes months to repair. I still can hear the repeatedly spoken, half understood sentences from the last encounter.
In short: It does not meet our quality standards (yet) but we are looking for volunteers who can help us. Are you interested ? :-)
Cheers, Marek
Experience is quite useful then :) I did play a bit with batman-adv for my master thesis on wireless mesh networks, but I realize my knowledge of the protocol itself is not that good as It should to add ideas or comments. Be sure I'll post the mailing list if I have any contribute to improve docs or anything.

I think you are well qualified then. :) Don't hesitate to comment on the document. You might be the right person to spot missing points, especially when you are not the protocol master.
