Multiple Versions of ns3 in Ubuntu 22.04 In this post, we are going to install two versions of ns3 namely ns-3.35 and ns-3.37  My OS is : Ubuntu 22.04 LTS (Long Term Support) ns-3.35 uses waf and (./waf --run scratch/first)  ns-3.37 uses cmake  (./ns3 run scratch/first.cc) So we will install both the packages  Go through the video for complete instructions To start with  $ sudo apt update  $ sudo apt install build-essential autoconf automake libxmu-dev g++ python3 python3-dev pkg-config sqlite3 cmake python3-setuptools git qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools gir1.2-goocanvas-2.0 python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython3 openmpi-bin openmpi-common openmpi-doc libopenmpi-dev autoconf cvs bzr unrar gsl-bin libgsl-dev libgslcblas0 wireshark tcpdump sqlite sqlite3 libsqlite3-dev  libxml2 libxml2-dev libc6-dev libc6-dev-i386 libclang-dev llvm-dev automake python3-pip libxml2 libxml2-dev libboost-all-dev  I have downloaded both the versions of ns3 fr

SUMO and MOVE Example Traffic Simulation

This post will show you the example of SUMO and MOVE using the Ubuntu 12.04 (64bit) operating system. Requirements: MOVE.jar (This software will work only with sumo version 0.12.3). SUMO (0.12.3)   jdk (To run MOVE) The command to run MOVE.jar is $] java -jar MOVE.jar Here is the screenshot of all the images. My Own Road with Traffic Signals  The above diagram shows there are 6 junctions (0 to 5) and the Traffic signals are at 1,2,4 and 5. There are roads connecting the junctions. Each Road has two lanes named R for Right, L for Left, U for Up and D for down. R12 indicates a lane from 1 to 2 and L12 indicates 2 to 1 To create simulation using MOVE, The following options in MOVE.jar have to be implemented.   Mobility Model Node (file.nod.xml) Edge (file.edge.xml) Configuration (file.netc.cfg) Create Map (file.net.xml) Flow (file.flow.xml) Turn (file.turn.xml) Create Vehicle (file.rou.xml) Configuration (file.sumo.cfg) - This file is the one running in

Simulation of Urban Mobility (SUMO) in Ubuntu 12.04

This post will tell you how to install SUMO 0.12.3 version in Ubuntu 12.04 LTS. Also this post will tell you how to use MOVE for generating VANETs Simulation scenario. OS Used: Ubuntu 12.04 LTS (64 bit) Sumo Version : 0.12.3 MOVE.jar (For this to work, Java runtime environment to be installed) (Also MOVE.jar will support only SUMO 0.12.3). The latest version of SUMO (at the time of writing this post) is sumo 0.21. Points to be noted: Its always better to use the latest software, but to begin with SUMO needs XMl files are roads, edges, vehicle routes, etc. So MOVE.jar file is just helping in creating the xml files needed by SUMO. But the recent versions of SUMO (0.21) and etc, the XML files are to be generated manually by means of any external xml editors or simply using gedit or vim. Also, the Ubuntu package manager comes default with sumo and sumo-gui command (that can be installed using the command sudo apt-get install sumo ,  but the python scripts like randomTrips.py, t

Prerequisites for learning NS2

At many places, I happen to see researchers and students wanted to use Windows for NS2 rather than Linux. The reason may be, Linux is tough It occupies more space and more memory in my Computer Linux uses lot of commands and i am not aware of it Tough to handle dual boot OS (windows and Linux) always wanted to be in the cakewalk. (never try a new thing) etc ns2 installation in Linux But here are some basic tips for using NS2 under a Linux Machine. It is enough to know some basic Linux commands to work with NS2 (hardly not more than 20 commands) One should have a basic knowledge of how tree structure in Linux/Unix look like Finally, where to set the PATH information in Linux With all the above three, one can confidentially work on Linux. As for as windows is concerned, upto NS2.27 version is tested under windows and recent versions there is no hope (however it will work fine, but “Use at your Own Risk”) Now we will see some basic Linux commands that are needed f
