I'm simulating a network in NS2, but i'm having a problem naming the nodes. I'm naming them from 1 to 10 but when i start it, it shows nodes from 0 to 9
set ns [new Simulator]
set nf [open out.nam w]
$ns namtrace-all $nf
set tf [open out.tr w]
$ns trace-all $nf
proc finish {} {
global ns nf tf
$ns flush-trace
close $nf
close $tf
exec nam out.nam &
exit 0
}
set n1 [$ns node]
set n2 [$ns node]
set n3 [$ns node]
set n4 [$ns node]
set n5 [$ns node]
set n6 [$ns node]
set n7 [$ns node]
set n8 [$ns node]
set n9 [$ns node]
set n10 [$ns node]
