wlanctl atw0
wlanctl may print this node table, for example:

This example is taken from a network consisting of three stations running in ad hoc mode. The key for interpreting the node print-outs follows:

``bss''
set uses
rssi
to indicate the signal strength for the last packet received from
a station that does not belong to the network.
On an infrastructure-mode station, the node with
node flag
``bss''
set indicates the strength of packets from the access point.
