Hmmm, one concern. There are now ''many'' laptops on your testbed that
could be shortcutting your multi-hop path. There are even some xo's
outside the lab but within wireless range that may be affecting your
tests.
To prevent this you should use the blinding table in inverted mode. When
the inverted flag is set all traffic is ignored '''except when it is
received from nodes in the table'''.
So, to set up a 3-hop path through nodes A, B, C and D you would:
Node A
{{{
iwpriv msh0 bt_set_invert 1
iwpriv msh0 bt_add B
}}}
Node B
{{{
iwpriv msh0 bt_set_invert 1
iwpriv msh0 bt_add A
iwpriv msh0 bt_add C
}}}
Node C
{{{
iwpriv msh0 bt_set_invert 1
iwpriv msh0 bt_add B
iwpriv msh0 bt_add D
}}}
Node D
{{{
iwpriv msh0 bt_set_invert 1
iwpriv msh0 bt_add C
}}}
Could you please retest with this configuration? If the test fails,
please include the output of the following commands for each node:
{{{
for i in `seq 0 127`; do iwpriv msh0 fwt_list $i; done
}}}
{{{
for i in `seq 0 16`; do iwpriv msh0 bt_list $i; done
}}}
{{{
iwpriv msh0 bt_get_invert
}}}
Thanks!
