Wireless Node Configuration in Network Simulator 2 (NS2)

The node configuration in ns2 is a special task in which the number of nodes can be configured for a set of parameters. The following table tells about the node  configuration parameters as defined in the ns-lib.tcl

The readers are requested to refer the ns-lib.tcl file for more information.

Option Available Values Remarks
addressType flat, hierarchichal  
MPLS ON,OFF Multi protocol Label Switching
wiredRouting ON, OFF  
llType LL, LL/Sat Link Layer
macType Mac/802_11, Mac/Csma/Ca, Mac/Sat, Mac/Sat/UnslottedAloha, Mac/Tdma Medium Access Control
ifqType Queue/DropTail, Queue/DropTail/PriQueue Interface Queue type
phyType Phy/wirelessPhy, Phy/Sat Physical Layer Type
adhocRouting DIFFUSION/RATE, DIFFUSION/PROB, DSDV, DSR, FLOODING, OMNIMCAST,AODV,TORA,PUMA adhoc routing protocol

mobileIP ON,OFF to set the IP for Mobile or not
energyModel EnergyModel energy model to be enabled or not
initialEnergy <joule> in terms of joules (Ex: 3.24)
txPower   Power in terms of Watts (0.32)
rxPower   Power in terms of Watts (0.1)
idlePower   Power in terms of Watts (0.02)
agentTrace ON, OFF Tracing to be on or off
routerTrace ON, OFF Tracing to be on or off
macTrace ON, OFF Tracing to be on or off
movementTrace ON, OFF Tracing to be on or off
errProc UniformErrorProc  
toraDebug ON, OFF

    2. depending on the type of network, you can set the power. for WSN, you can get the power history of a IRIS or MICA and set the corresponding values, for a wifi network, set power based on the battery profile of the device.....

  2. I am facing error,

    segmentation fault(core dumped)

    Please help me..

ns3 installation in Ubuntu 16.04

This post serves the installation instructions of ns3 in ubuntu 16.04 version. Some of my students are working in ns3, this post will benefit them in installing ns3.

OS Used: Ubuntu 16.04.4
ns3 version: ns3 version 3.27

The same procedure will be applied for OS like Debian, Linux Mint.

Fresh installation of Ubuntu 16.04 Let you try the fresh installation of ubuntu in your hard disk along with windows.
Installation of ns3 dependencies ns3 needs so many dependencies, developmental libraries, drivers, etc. so install all those
$] sudo apt update  $] sudo apt upgrade
$] sudo apt-get install build-essential autoconf automake libxmu-dev python-pygoocanvas python-pygraphviz cvs mercurial bzr git cmake p7zip-full python-matplotlib python-tk python-dev python-kiwi python-gnome2 python-gnome2-desktop-dev python-rsvg qt4-dev-tools qt4-qmake qt4-qmake qt4-default gnuplot-x11 wireshark
The above command make take some time to download, compile and install it, Be Patient.

TORA Protocol in NS-2.35 (NS2)

This post tells you how to enable the TORA (Temporally ordered routing Algorithm) protocol in Network Simulator 2 (ns-2.35)

TORA is a protocol in wireless adhoc networks that works with timing parameters. NS-2.35 comes with the TORA protocol by default but it has to be tweaked manually to make it run.
This post will help you to do that.

You can watch this video for detailed instructions:


Step 1: Generate a Scenario for TORA protoco using NS2 Scenario Generator NSG Software.
We have created a tcl file using NSG2.1.jar

$] java -jar NSG2.1.jar

Three files have to be modified
~ns-2.35/tora/tora.cc~ns-2.35/tora/tora.h~ns-2.35/imep/imep.cc There are various websites that tells you how to configure TORA by making changes to the above three files.  Change 1: tora.h In the tora.h file, go to the end of the File before the agent completes, include these two lines

#include <classifier/classifier-port.h>
protected: PortClassifier *dmux_;

Change 2: tora.cc Open the tora.cc and include the follow…
