Hello all, I've been developed a wireless network emulator for IoT (https://github.com/ramonfontes/mininet-iot) in which I'm using mac802154_hwsim. Mininet-IoT extends Mininet-WiFi (https://github.com/intrig-unicamp/mininet-wifi) by simulating WiFi through mac80211_hwsim. Mininet-WiFi already supports 6lowpan with fakelb and I moving everything to mac802154_hwsim. Since I'm using iwpan with mac802154_hwsim and given the expertise of this community, I was wondering whether there is any work in which simulate the data rate based on the distance/rssi with 6lowpan. If the answer is no, what would be the best way to do so? I was thinking of doing this with TC, but TC wouldn't work well with multiple hops. Should I develop a wmediumd-like simulator (https://github.com/bcopeland/wmediumd) for mac802154_hwsim? Best regards, Ramon Fontes
