Hi all, as anticipated some weeks ago, I'm working on a modification of B.A.T.M.A.N. routing metric in order to take into account link bit-rate. As already exposed, in my opinion, it is important to consider bit-rate because there isn't any correlation between TQ and the physical capacity.
I have called the new metric PCE (Physical Capacity Estimation), which is defined for each path as the minimum value of (tq_local * bit-rate) among all the link forming it.
After a quick and dirty modification of the code, I've done some test on two simple topologies to verify whether there is an improvement or not. From this preliminary test seems that the improvement is remarkable.
In the attached report there is a better explanation of the modification, and the results from the tests. Any comment will be appreciated!!
Regards.
