What Version: ns-3.29
My Ubunut OS is: Ubuntu 18.04

This file we are going to use for our simulation:
/home/networks/ns-allinone-3.29/ns-3.29/examples/routing/manet-routing-compare.cc

Once you under stand the code, now lets run this example

Step 1: Copy the above file in to ~ns-3.29/scratch/ folder

Step 2: Understand this code.
Step 3: Run this code
Open the terminal, Go to ns-3.29 and run the following command

$] ./waf --run scratch/manet-routing-compare

enable the following header file

#include "ns3/flo…

Manual tracing–tracefile

Assume you created a tcl file for a wireless simulation and it generates a trace file (usually .tr as extension). If any tracing softwares are not available, how to interpret manually, here is the step
ACTION: [s|r|D]: s -- sent, r -- received, D – dropped

WHEN: the time when the action happened

WHERE: the node where the action happened

LAYER: AGT -- application, 

RTR -- routing,  LL  -- link layer (ARP is done here) IFQ -- outgoing packet queue (between link and mac layer) MAC -- mac,  PHY – physical

flags:

SEQNO: the sequence number of the packet

TYPE: the packet type  cbr -- CBR data stream packet  DSR -- DSR routing packet (control packet generated by routing)  RTS -- RTS packet generated by MAC 802.11  ARP -- link layer ARP packet

SIZE: the size of packet at current layer, when packet goes down, size increases, goes up size decreases[a b c d]: a -- the packet duration in mac layer header  b -- the mac address of destination  c -- the mac address of source  d -- the mac type of the packet body

flags:

[......]: [  source node ip : port_number  destination node ip (-1 means broadcast) : port_number  ip header ttl   ip of next hop (0 means node 0 or broadcast)  ]


So we can interpret the below trace 


s 0.0297823400 _1_ RTR --- 2012 cbr 32 [0 0 0 0] ------- [1:0 0:0 32 0]


as Application 0 (port number) on node 1 sent a CBR packet whose ID is 2012 and size is 32 bytes, at time 0.029 second, to application 0 on node 0 with TTL is 32 hops. The next hop is not decided yet.


And we can also interpret the below trace


r 0.010176954 _9_ RTR  --- 1 gpsr 29 [0 ffffffff 8 800] ------- [8:255 -1:255 32 0]


in the same way, as The routing agent on node 9 received a GPSR broadcast (mac address 0xff, and ip address is -1, either of them means broadcast) routing packet whose ID is 1 and size is 19 bytes, at time 0.010176954 second, from node 8 (both mac and ip addresses are 8), port 255 (routing agent).

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…
