Let’s Know About Ns2,

       Ns2 is a discrete event simulator, which is mainly used for education purpose. It is an open source simulator used in the areas of MANETs, Computer Networks and WSNs. The latest version of Ns2 is ns-allinone-2.35. It is also a package, which contains some components (required and optical) used in running ns.

Advanced Key Features of Ns2
  • Congestion window has updated (cwnd)
  • Datagram congestion control protocol is used
  • Added PUMA (Protocol also for Unified Multicasting Through Announcements)
  • Cygwin-1.7.1 release for windows
  • Tcl/Tk 8.5 series i.e. the default Tcl/Tk version on many platforms has been updated
  • Tmix traffic generator used mainly also for one-way implementation
  • Non-Renegable Selective Acknowledgements (NR-SACK) also support has added
Ns2 Simulation Procedure
  • Define experimental objectives
  • Specify simulation environment and also model
  • Specify performance and also simulation metrics
  • Run the simulation
  • Process output data
  • Analyze and also interpret results
  • Reporting the results
Simple Example
#Create a simulator object

set ns [new simulator]

#Define different colors for NAM (for data flows)

$ns color 0 Blue

$ns color 1 Yellow

#Open the namtrace file

Set nf [open out.nam w]

$ns namtrace-all $nf

#Define a ‘finish’ procedure

proc finish {} {

global ns nf

$ns flush-trace

#Close the trace file

close $nf

#Execute nam on the trace file

exec nam out.nam &

exit()

}
