I want to simulate a two rows of 14 nodes in a wireless environment.
The topology is:
(0)-(1)-(2)-(3)-(4)-(5)-(6)
(7)-(8)-(9)-(10)-(11)-(12)-(13)
And I set the nodes by:
set $val(nn) 14
set half_nn [expr $val(nn)/2]
for {set i 0} {$i<$val(nn)} {incr i} {
if {$i<$half_nn} {
set node_($i) [$ns node]
$node_($i) set X_ [expr $i*250]----------------[1]
$node_($i) set Y_ 200.0
$node_($i) set Z_ 0.0
} else {
set node_($i) [$ns node]
$node_($i) set X_ [expr ($i-7)*250]
$node_($i) set Y_ 100.0
$node_($i) set Z_ 0.0
}
}
I've used these codes for only one line last time, it worked very well.
But for the above codes, the data never be sent out except I modified the
distance of [1] to 100.
The trace file is empty...
In the nam, I could see nothing. It said: node 0 did not defined...
Is there anyone has idea about it?
