This document explains how to deploy a virtual network using SDN-WISE, Cooja, Mininet and ONOS in a Virtual Machine (VM). The target of this document is to create an integrated network controlled by ONOS where a virtual network of OpenFlow switches can communicate with the nodes of an emulated SDN-WISE wireless sensor network.

Step 1: Virtual Machine

We begin by downloading Instant Contiki, installing VMWare Player, and booting up Instant Contiki. You can find more details on Contiki and Instant Contiki here.

Download Instant Contiki and Install VMWare Player

Download Instant Contiki from here. It is a large file, just over 2GB. When downloaded, unzip the file, place the unzipped directory on the desktop. Then download and install VMWare Player from here. It is free to download. It might require a reboot of your computer, which is unfortunate but needed to get networking working.

Boot Ubuntu

Start Instant Contiki by running Instant_Contiki_Ubuntu_12.04_32-bit.vmx. Wait for the virtual Ubuntu Linux boot up. Log into Instant Contiki. The password is user. Log in.

Step 2: Setup the environment

Now we will download the source code for SDN-WISE, Contiki, Mininet and ONOS.

Download the needed software

First open a new terminal window ( press Ctrl+Alt+t ). The following script will download and compile all the needed software for the tutorial.

cd && wget https://raw.githubusercontent.com/sdnwiselab/onos/onos-sdn-wise-1.10/tools/tutorials/sdn-wise/sdn-wise.sh && sudo chmod +rx sdn-wise.sh

Insert the password user when prompted and run the script using the following command:

sudo ./sdn-wise.sh

Compile ONOS

Write in the terminal:

echo "export ONOS_ROOT=~/onos" >> ~/.bashrc && source ~/.bashrc && source $ONOS_ROOT/tools/dev/bash_profile && cd ~/onos &&
tools/build/onos-buck build onos --show-output && tools/build/onos-buck run onos-local -- clean debug

Congratulations! You have just installed SDN-WISE, ONOS, Mininet and Contiki!

Step 3: Start!

Now we will start all the downloaded softwares. After these steps your VM may run short on RAM, if this is you case please use this link to learn how to increase the RAM assigned to the VM.

Start ONOS

Start ONOS in a new terminal:

cd ~/onos && tools/test/bin/onos localhost

Then run:

app activate org.onosproject.sdnwise

Now you can open a browser pointing to http://localhost:8181/onos/ui (in a terminal write xdg-open http://localhost:8181/onos/ui).

Input user as user and rocks as password.

Start Mininet

Open a new terminal and write:

sudo mn --topo tree,depth=2,fanout=3 --controller=remote

When Mininet is started run the pingall command. Mininet pingall.

Start Cooja

To start cooja write in a new terminal:

cd ~/sdn-wise-contiki/contiki/tools/cooja/ && ant run

When Cooja is started, it will show a blue empty window. Cooja. Click on Settings -> Cooja extensions... Cooja extensions Enlarge the left part of the window, scroll down and select sdn-wise-emulated sdn-wise-emulated Then click on Apply for session

Step 3: Create a heterogeneous network

Create a new simulation

Clik on File -> New simulation... New simulation.

Set simulation options

Enter as simulation name SDN-WISE. Click the Create button. Simulation name.

Simulation windows

Cooja brings up the new simulation. The Network window, at the top left of the screen, shows all the motes in the simulated network - it is empty now, since we have no motes in our simulation. The Timeline window, at the bottom of the screen, shows all communication events in the simulation over time - very handy for understanding what goes on in the network. The Mote output window, on the right side of the screen, shows all serial port printouts from all the motes. The Notes window on the top right is where we can put notes for our simulation. And the Simulation control window is where we start, pause, and reload our simulation. Cooja windows.

Add Java Emulated SDN-WISE nodes

In this tutorial we will teach you how to add some Java emulated SDN-WISE nodes and then we will give you the details on how to use Contiki Simulated nodes. For the Java ones, let’s start by adding a Sink. Click on Motes -> Add motes -> Create new mote type -> SDN-WISE Emulated Sink... SDN-WISE Emulated Sink. then click on Create… SDN-WISE Emulated Sink. …and Add motes. SDN-WISE Emulated Sink. Then we repeat the same commands for the other nodes of the network, but this time we choose Motes -> Add motes -> Create new mote type -> SDN-WISE Emulated Mote... SDN-WISE Emulated Sink. and we add 5 motes instead of one.

Setup the windows

In the Network window, click on View. The following items should be selected:

  • Mote relations
  • Mote IDs
  • Radio traffic
  • 10m background grid
  • Mote type
  • Radio environment (UDGM) Network window. Click on Tools -> Radio messages. A new window will appear. This window will show all the details regarding the messages sent over the Radio. We are going to use it later. Check that all the nodes can be reached by the sink, directly or by multiple hops. You can see it by clicking on a node. A green circle will appear. All the nodes inside the green area can be reached by the selected one. There is also a gray circle. This circle represents the interference area of the node. Now we will setup the simulation speed. Because we need to interact with an external controller, in the Simulation control window click on Speed limit and select 100%. Simulation control window. At this moment everything should be set and we can run the simulation by clicking on the menu Simulation -> Start simulation. When prompted insert localhost:9999 as the location for the controller. Controller Address.

Conclusions

Finally if you check your browser you will see that ONOS has recognized the whole network and it is now ready to route packets between the Mininet hosts and the SDN-WISE nodes. Integrated Networking.
