There is another suggestion: You could increase the multicast rate to a high value, e.g. 36 MBit/s or even higher. Higher rates only work with good signals, and since batman-adv uses broadcasts (which is multicast for WiFi), this will have a direct effect on your network.

Batman-adv is open source, and so is mac80211 and hopefully the WiFi driver you use. However, it'd really suggest to start with tuning the multicast rate. :)
I definitely agree here. This should tested before trying to hack the TQ calculation with some own RSSI based submetric.
The mcast_rate trick is currently only shown in an old OpenWrt wiki page [1]. Maybe it should also be mentioned in the main OpenWrt configuration page [2]. I will leave this to the interested reader... or I will change it when I have some time to confirm it with a current OpenWrt.
Kind regards, Sven
