OMNeT++ Sumo Veins project

VANET routing protocol comparison in a realistic traffic scenario using the OMNeT++ Sumo Veins Project can be effectively carried out by following the structured steps below:

1. Create a new OMNeT++ project: Open the OMNeT++ IDE, go to File > New > Project. Select the “Empty Project” template, click “Next,” enter your project name, and click “Finish.”

2. Add the SUMO and Veins frameworks: Right-click on the project in the OMNeT++ IDE and select Properties. Under the “Frameworks” category, click “Add,” select the SUMO and Veins frameworks, and confirm with “OK.”

3. Create a new SUMO network topology: In the SUMO GUI, go to File > New, select the “Empty Network” template, and name your network. This forms the base for comparing VANET routing using the OMNeT++ Sumo Veins Project.

4. Configure the SUMO network: Enable VANET routing support by setting appropriate network parameters in the SUMO configuration files.

5. Create a new Veins scenario: Right-click on your project in OMNeT++ IDE, choose New > Veins Scenario, name it, and click “Finish.” This scenario will define your vehicular environment for the simulation.

6. Configure the Veins scenario for routing protocol comparison: Open the scenario file and add the following attributes inside the <mobility> section to enable multiple VANET routing protocols.

  <attribute name="routing_protocol" value="AODV"/>
  <attribute name="routing_protocol" value="OLSR"/>
  <attribute name="routing_protocol" value="GPSR"/>

7. Develop the OMNeT++ application: Create a new class in OMNeT++ that inherits from the cSimpleModule class. Implement message generation, transmission, and reception logic to measure performance metrics across different routing protocols within the OMNeT++ Sumo Veins Project.

8. Run the OMNeT++ simulation: Once the configuration is complete, right-click on the project and select Run to start your simulation.

9. Analyze and compare results: Evaluate the VANET routing protocol performance using key metrics such as:

• Packet Delivery Ratio (PDR)
• End-to-End Delay
• Routing Overhead
• Throughput

By conducting this detailed comparison using the OMNeT++ Sumo Veins Project, researchers can accurately measure the performance, scalability, and reliability of various VANET routing protocols in realistic traffic conditions.
