[B.A.T.M.A.N.] Question about sliding windows in Batman-adv 2015.0

[Jérôme GRIES]

Hello everybody (thx to Marek Lindner for the answer)

My name is Jérôme, i'm a French student  in informatics and networks, 
for a project i use BATMAN ( i use it with raspberry Pi in cars).

I would like to change the duration of the sliding windows, i understand 
that the duration of the sliding windows is equals to 128*intervall it 
(intervall beetween every hello packets)

So normally the sliding windows is equals to 128 seconds because the 
interval is 1s in default mode.

I would like to change  the code to change this duration but not just 
with the interval it value but directly with the 128. Because when i use 
this protocol in a mobile environment like cars this value is to high, 
and i would like to reduce in something like sliding windows duration = 
30*5(=interval it which i can change easily).


Could you tell me where i can find something like that in the code :

#define _timeslidingwindows 128



Thank you and have a nice day.

Jérôme Gries

all protocol defines / parameters can be found in net/batman-adv/main.h. The 
one you are looking for is this:

/* sliding packet range of received originator messages in sequence numbers
 * (should be a multiple of our word size)
 */
#define BATADV_TQ_LOCAL_WINDOW_SIZE 64

Cheers,
Marek
