Hi,
I would like to to get a mobile node coordinates at a given time in TCL
script. I have a procedure like this:
proc getLocations { node_a tstart tend } {
set time-step 0.1
set t $tstart
set x -1
set y -1
while {$t <= $tend} {
puts "t is $t----x=[$node_a set X_] ----y=[$node_a set Y_] "
set t [expr {$t + $time-step}]
}
}
$ns at 0 "getLocations $n(0) 0 $val(stop)";
But -x=[$node_a set X_] ----y=[$node_a set Y_] always return the initial
values of X_ and Y_ even if the node moves.
Do you know what should I do?
I see that by setting "Movement trace ON " in node configuration you can
print nodes positions in the trace file but how can I access them via TCL, I
think I should use the GOD object, but not sure how can I do it using only
TCL script.
Thanks for your help,
Best,
Behnaz
