[B.A.T.M.A.N.] BATMAN Advanced Kernel: how much time to find a new route?

Hi,

I'm studying how BATMAN Advanced-Kernel work. I'm interesting in knowing what is the behavior of BATMAN and the reaction time of the protocol if a node exit from a range node and entered in another range node. I have discovered that (in a simulation with 3 hosts with a mobile node and 2 static node) BATMAN find a new route losing more or less 8 seconds, passing from one to the other node. But the OGMs time is 1 s and the sliding window is 64, so why it can lost 64 seconds to find another route (or 32)?

So there is a equation to define a the time lost to find a new route?

I have an originator interval of 1 seconds (set by default).

Thank you

Paolo
