VANET Simulation

This project involves the real-time simulation of Vehicular Ad-Hoc Networks (VANET) using NS3 and SUMO.

WAVE (Wireless Access for Vehicular Environments)

Tools Required

Operating System: Ubuntu 16.04 LTS
NS3 Version: ns-3.29
SUMO Version: Eclipse SUMO Version v1_5_0+1154-40cc386
Additional Tool: OpenStreetMap (osmWebWizard.py)

Steps:

Step 1: Open OSM Web Wizard

$ cd sumo/tools
$ python osmWebWizard.py

Step 2: Process and Generate vanettrace.xml

$ cd sumo/tools/2022-06-07-11-58-26/
$ sumo -c osm.sumocfg --fcd-output vanettrace.xml

Step 3: Generate vanetmobility.tcl

$ cd sumo/tools
$ python traceExporter.py -i 2022-06-07-11-58-26/trace.xml --ns2mobility-output=2022-06-07-11-58-26/vanetmobility.tcl

Step 4: Add NetAnimation File

#include "ns3/netanim-module.h"
AnimationInterface anim("Vanetanim.xml"); // Add before Simulator::Run();

Step 5: Add Performance Analysis Code

// Network Performance Calculation
// Add performance analysis code to the vanet program

///////////////////////// Network Perfomance Calculation ///////////////////////

Step 6: Configure Scenario 2

// Configure scenario 2
else if (m_scenario == 2)
 {
      // Realistic vehicular trace in KCT
      // "low density, 21 total vehicles"
      m_traceFile = "/adhoc/sumo/tools/2022-06-07-11-58-26/vanetmobility.tcl"; //path to "vanetmobility.tcl" file
      m_logFile = "vanet.log";
      m_mobility = 1;
      m_nNodes = 21;
      m_TotalSimTime = 150.01;
      m_nodeSpeed = 0;
      m_nodePause = 0;
      m_CSVfileName = "vanet.csv";
      m_CSVfileName = "vanet2.csv";
    }

Step 7: Run the Program

$ ./waf --run "scratch/vanet-routing-compare --protocol=1 --scenario=2"

Step 8: Open NetAnim

$ cd ns-allinone-3.29/netanim
$ ./NetAnim

Load Vanetanim.xml file in NetAnim to visualize the network animation.
