How to simulate cooja os contiki simulator projects?

Numerous procedures are included in the process of simulating projects in the Contiki OS through the utilization of its Cooja simulator. It generally ranges from arranging the platform to examining outcomes of the simulation. For simulating wireless sensor networks (WSNs) which execute Contiki OS, Cooja simulator is considered as a robust tool. To test protocols and applications in a virtual platform, this tool supports researchers and developers. We offer a step-by-step procedure that assists you to initiate this process appropriately:

Step 1: Install Contiki OS and Cooja Simulator

1. Download Contiki: From the official GitHub page, download or copy the Contiki OS repository. To install contiki on your system, it will need various tools such as build-essential, Git, doxygen, and Java for Cooja.
2. Navigate to Cooja: Go to the Cooja directory after downloading the Contiki. Typically, you can identify it by contiki/tools/cooja.
3. Launch Cooja: In the Cooja directory, run the command ant run to execute Cooja. The Cooja simulator will be compiled and initiated through this process.

Step 2: Develop a New Simulation

1. Initiate a New Simulation: Choose the “New Simulation” icon or navigate to File > New Simulation in Cooja.
2. Configure the Simulation: It is important to specify a proper name for your simulation. The major simulation arguments like begin time and simulation time speed have to be arranged.

Step 3: Add and Configure Nodes

1. Append Motes (Nodes): For appending motes (nodes), navigate to Motes > Add Motes > Create new mote type. Then, the kind of mote that you intend to append in your simulation has to be chosen. There are numerous kinds of motes such as Sky mote, Z1 mote, etc and you can select anything from them. If particular hardware arrangements are needed by your project, you can also select custom mote types.
2. Configure Each Mote: By encompassing firmware that is the application of Contiki OS to execute, other certain hardware settings, and location in the simulation platform, arrange the settings for every node.

Step 4: Set Up Network Settings and Interactions

1. Network Topology: To indicate your determined network topology, your nodes have to be configured into the simulation platform. For simulating actual-world placement contexts, the process of deploying nodes in particular positions might be included.
2. Communication Links: The wireless interaction connections among nodes can be simulated by the Cooja in an automatic manner, but to demonstrate various states, you can adapt connection arguments such as signal strength, interference, and distance.

Step 5: Execute the Simulation

1. Begin the Simulation: By selecting the “Start” button, initiate the simulation, especially when your nodes are arranged and deployed properly. Based on your requirements, you can stop, halt, or alter the simulation speed.
2. Interact with Nodes: To modify settings, input commands, or gather data, you can communicate with each and every node at the time of simulation process. This specifically enables testing network applications and protocols in a dynamic way.

Step 6: Monitor and Analyze the Simulation

1. Utilize Visualization Tools: For visualizing the network and its functioning such as logging windows for every node, packet transmission animations, and radio environment visualization, Cooja provides different tools.
2. Gather Data: To gather data related to energy utilization, network performance, packet loss, and other suitable indicators, use the logging and tracing abilities of Cooja.
3. Analyze Outcomes: In order to assess the activity and performance of your network protocol or application, examine the gathered data after the simulation process. For data analysis, you can employ various tools such as Python scripts, Excel, or Matlab.
