Pb With Configuring Simulator

Hi all i hav problem in NS2. whenever creating an new simulator it shows an error for invalid command name "new". how to solve this problem plz help me

Thanks in advance

Nanda

I have implemented black hole attack in AODV protocol. I simulated it through NS2 simulator and every time during building the simulator the simulator is built but after the result analysis and observing the NAM simulation I saw that the black hole is not working properly . The packets are not being dropped. So if anybody has done that please suggest me where should I correct my errors.

What is the best simulator for OBS networks? Why?
Is it obs-ns? matlab? n-obs? pleaseeeeeee help me.

Hi,
I am new in linux. I have following problem while running the codes of TORA in ns-2.35 in ubuntu.Can you please help me?

i m running file following tcl script but terminal shows nothing no error no nam file nothing
whats wrong with this script??????


set ns [new Simulator]

set nf [open out.nam w]
$ns namtrace-all $nf

proc finish {} {
global ns nf
$ns flush-trace
close $nf
exec nam out.nam &
exit 0
}

for {set i 0} {$i < 7} {incr $i} {
set n($i) [$ns node]
}

for {set i 0} {$i < 7} {incr $i} {
$ns duplex-link n($i) n([expr ($i+1)%7]) 1mb 10ms dropTail

$ns at 5.0 "finish"

$ns run

i write ns example3.tcl on terminal but terminal shows nothing even after waiting for long. when choose to close terminal it shows msg something running want to kill terminal

Hi

It's my first post,please bear with us.I write thesis "The concept of using energy metrics for route selection in OLSR routing protocol". I use the simulator ns2, and UM-OLSR patch. In tlc script I use "Energy model". How and where(in code, or tcl cript) I can change parameter "willingness" during simulation to take into account the level of battery.


pseudocode

if (battery < 1.0) && (battery > 0.8)
{willingnes = WILL_ALWAYS};
else if (battery < 0.8) && (battery > 0.4)
{willingnes = WILL_DEFAULT};
else if (battery < 0.4) && (battery > 0.2)
{willingnes = WILL_LOW};
else if (battery < 0.2)
{willingnes = WILL_NEVER};

I m learning Tcl and write short code. After running code i got same error repeatedly and not able to find mistake,,,i wrote it as it is from a tutorial. here is the code below

set ns [new Simulator]

set f1 [open out.nam w] #open nam file out.nam
$ns namtrace-all $f1

proc finish{} {
global ns f1
$ns flush-trace
#close $tracefile1
close $f1
exec nam out.nam &
exit 0
}
