+== Contiki
+
+Contiki is a state-of-the-art, open
+source  operating  system  for  sensor  networks  and  other  networked  embedded
+devices 
+
+
+More Info: 
+https://en.wikipedia.org/wiki/Contiki[^]
+
+
+== Start Instant Contiki
+
+
+.Start VMware and  load Instant Contiki.
+[source,bash]
+----
+unzip InstantContiki2.7.zip
+vmplayer
+----
+Start  image
+
+== Log In
+When the login screen appears, log in to Instant Contiki:
+
+.Log In usermode
+[source,bash]
+----
+Username: user
+Password: user
+----
+
+.Log In sudo
+[source,bash]
+----
+sudo apt update 
+Password: user
+----
+
+== Open a Terminal
+
+After  logging  in,  click  on  the  terminal  icon  to  start  a  terminal  window.   
+
+== System test
+
+
+.compile hello-world 
+[source,bash]
+----
+cd contiki/examples/hello-world/
+make TARGET=native
+----
+
+.Run the Hello World program in Contiki:
+[source,bash]
+----
+./hello-world.native
+----
+
+The program should print the words *“Hello, world”* on the screen and then appear to hang.  
+
+In reality, Contiki is still running correctly,  but will not produce any output because the Hello World program has finished.  
+[source,bash]
+----
+Press Ctrl+C on the keyboard to quit.
+----
+
+
+== Simulating Contiki with COOJA
+
+=== Start COOJA
+
+.start
+[source,bash]
+----
+cd contiki/tools/cooja/
+ant run
+----
+
+[NOTE]
+.INFO
+====
+COOJA  compiles,  and  after  a  few  seconds  the  simulator  appears.   
+
+All  COOJA  simulations  are  controlled  using plugins:  small Java programs that interact with simulations and simulated nodes.  
+
+When COOJA is started,  no simulation is loaded and no plugins are started.
+====
+
+=== Create a simulation
+
+A new simulation is created via the menu.
+
+[source,bash]
+----
+File > New > Simulation
+----
+
+- Enter a Simulation title, and click Create.
+
+We have now created our first simulation in COOJA. However, the simulation does not contain any nodes yet.  
+
+To add nodes we need to first create a node type, and then add nodes to the simulation.
+
+=== Create a node type
+
+Any simulated node in COOJA belongs to a node type.  
+
+The node type determines, among others, which Contiki applications to simulate.  
+
+
+Click menu item  
+
+[source,bash]
+----
+Motes > Add Motes > Create new mote type > Sky mote.  
+----
+
+You have selected to emulate Tmote Sky nodes, and now need to select what Contiki program to simulate.
+
+- Enter a Description.
+- *Click Browse*, and navigate to *contiki/examples/hello-world/hello-world.c*
+- *Click Compile* to start compiling the Contiki program
+- *Click Create* when complication finishes.
+
+You  will  be  asked  to  enter  the number of motes of your simulation.  
+
+Once you are done, click the Start button in the Simulation control window to start the simulation.
+
+
+
+=== Save, Load and Reload in Cooja
+
+Cooja allows for saving and loading simulation configurations.  
+When a simulation is saved,  all active plugins are also stored with the configuration.  
+
+.save your current simulation
+[source,bash]
+----
+File > Save simulation
+----
+
+.Open simulation
+[source,bash]
+----
+File > Open simulation > Browse...
+----
+
+Select a simulation configuration.
+
+When a simulation is loaded, all simulated Contiki applications are recompiled.
+
+
+.reload your current simulation:
+[source,bash]
+----
+File > Reload simulation  
+or press
+Ctrl+R
+----
+
+.Reminder
+[NOTE]
+====
+Reloading can be used to reset the simulation – to restart all nodes.  
+
+More importantly, reloading a simulation will recompile all Contiki code, useful while developing Contiki programs.  
+====
+
+
+
+=== Add simulated nodes
+
+[source,bash]
+----
+Motes > Add motes > [your type description]
+----
+
+Enter the number of nodes you want to simulate (e.g., 5), and press Add.
+
+
+=== Show properties
+
+Go to the *“Network”* window, click the *view* menu, and choose the properties you want to show for the nodes.
+
+
+==== Radio model in Cooja
+
+From the Network window,  click on the 
+
+[source,bash]
+----
+View > Radio Environment (UDGM)
+----
+
+
+If you now left-click on one of the nodes,  you will see a green circle around the selected node.  
+
+[NOTE]
+====
+The green circle presents the transmission range of the node, i.e.  the selected node can communicate with all other nodes within that circle.
+
+You may also see a grey circle around the green circle. 
+A  node  in  the  grey  area  cannot  receive  packets  correctly
