Based on the error:
can't read "topoInstance_": no such variable
while executing
"$node add-interface $chan $propInstance_ $llType_ $macType_ $ifqType_
$ifqlen_ $phyType_ $antType_ $topoInstance_ $inerrProc_
I guess that you did not creat an area so that the mobile node will be able
to move around. The code to create area follows.
# Create a topology
set topo [new Topography]
$topo load_flatgrid 2000 2000
Hope this might help.
