I think my explanation was too complicated. So here is what I think it should
WIRED CSMA WIRELESS CHANNEL
O O )) (( O )) (( O
N3 N0 N1 N2
When N2 is going to Tx to N3, it sends his packets to the next hop which is N1,
with final destination N3.N2 does this by broadcasting an ARP for N1. N1
replies, and gets the packet, and knows that to get to N3, it needs to use the
next hop N0. Again ARP is sent from N1. N0 replies, gets the packet and knows
it has to send it to N3 through interface 0. It broadcasts an APR and N3
Is this correct? that is the only way I see this works on real networks, since
ARP is broadcast.
Mathieu, setting the nodes up with different /32 address makes the global
routing crash. I changed
wifiInterfaces = address.Assign (wifiDevices);
and Global routing crashes...
