Installing ns-3.37 and ns-3.35 in Ubuntu | Ubuntu 22.04 | NS3

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

IOT - Border Router in Contiki OS

This post shows the introduction of Border router in Contiki OS. Border router or edge router is connected to internet when the other sensor nodes are reporting the data via the border router.
Implementation of this router is provided by all IOT operating systems.
Using this border router, how to transmit data to the internet, how neighbours are understood and how the routes are computed.
This example shows the implementation of Border router in Contiki OS

OS Used: Contiki 2.7
Simulator : Pooja

Step 1: Contiki Selection

Open Instant Contiki (Which runs on VMWare or Virtual Box)
Open Cooja from the Desktop directly or Open the Terminal and give the following steps

$] cd /home/user/contiki-2.7/tools/cooja
$] ant run 
If you want to simulate huge number of nodes then 
$] ant run_bigmem

Step 2: Selecting Border router

File - New Simulation -> Enter Simulation Name (Leave the defaults as it is ) and then Click "Create"

Click Add Motes -> Select Sky Mote

In the Firmware, Select the following path /home/user/contiki-2.7/examples/ipv6/rpl-border-router/border-router.c
Click -> Compile (or Clean and then Compile), once compilation is over, Click Create motes and select the number of motes (1 in this case)

Step 3: Create WebSense Nodes (Sky Websense)

Click Add Motes -> Select Sky Mote
In the Firmware Settings, Select /home/user/contiki-2.7/examples/ipv6/sky-websense/sky-websense.c
Click Clean and then Compile. After the compilation is over, Click Create and Select the required number of nodes (5 in this case)

So there are totally 6 motes (5 Websense motes and 1 border router mote). see Fig 1 Below. It shows one green coloured mote called border router and other yellow coloured motes 5 in numbers.
Fig 1 - Cooja Simulator

Step 4: Run the Simulation 

In the Simulation Control window, you can press the Start button to start the simulation. Since this application is deployed with IpV6 for all the nodes, it can be seen from the simulation that all the motes have the ipv6 addresses like this
mote 1: aaaa::212:7401:1:101 for Border router

A bridge has to be made between the border router and the other motes, to enable the bridge,
Right Click Border Router Node -> Mote tools for Sky 1 ->  Serial Socket (SERVER) 

Step 5: Bridge the Border Router

Open a new terminal and select the path as given below

$] cd /home/user/examples/ipv6/rpl-border-router/
$] make connect-router-cooja 
It will ask to input the super user password, after you input, the ipv6 addresses will be assigned to the motes.
You may ping it using a new terminal, with the command "ping6 aaaa::212:7402:2:202"

Step 6: Read the sensors
You can read the sensors using the ipv6 addresses by opening the firefox browser.
Open the browser and input the following addresses in a new tab

http://[aaaa::212:7401:1:101]
This will print the neighbours and routes from the border router

http://[aaaa::212:7402:2:202]
This will print the sensor readings like temperature and light as per the corresponding values.
See Fig 2 and Fig 3

 This example shows the connectivity of various motes with the border router.
for detailed explanation, you may look the youtube video.
