How Run Ns2 Program in Linux

In general, our research professionals have highlighted notable steps that are required to run the program based on network simulator 2 on Linux.

Phase: I

Initially, we have to download the packages based on network simulator 2 in Linux using the below mentioned web link.

Link to Download Ns2

Phase: II

Following that, we have to execute the commands that have been highlighted in the following to install Ns2.34 in Linux.

cd ./ns-allinone-2.34/

sudo ./install

Phase: III

Consequently, we have to create the Tcl program code in project location based on the Linux environment and the codes have been highlighted in the following.

  • Code to create object for network simulation and trace files

set ns [new Simulator]

set tracefile [open w]

$ns trace-all $tracefile

set namfile [open droptail_main.nam w]

$ns namtrace-all $namfile

  • Code to create UDP traffic

set udp [new Agent/UDP]

set null [new Agent/Null]

$ns attach-agent $n0 $udp

$ns attach-agent $n3 $null

$ns connect $udp $null

  • Code to create application

set cbr [new Application/Traffic/CBR]

$cbr attach-agent $udp

Phase: IV

Finally, we have to run the Ns2 program in Linux through the execution of below mentioned commands.

cd /home/research/ns2_with_droptail

sudo ./ns NS2_Program.tcl
