Routing in VANETs using ns3 - Part 2

Please watch the First Part before watching this video    • Routing in VANETs using ns3 - Part 1   Part 2 - Analysis of the results. Please go through the first video (Part 1) and then watch this video (PArt 2) #VANETs #NS3 #Routing 1. SUMO for web traffic (osmWebWizard.py) 2. Convert this into mobility.tcl file and that can be loaded to vanet-routing-compare.cc file (as discussed in part1) 3. We will be analysing various metrics like Receive Rate Packets Received Mac PHY overhead Packetloss Throughput and other metrics. Files that are generated mobility.tcl (for generating traffic in the network) .tr (Ascii Trace, throughput and goodput) .flowmon (FlowMonitor) .xml (for NetAnim) .pcap (Wireshark) Step 1 - SUMO $] export SUMO_HOME=/home/pradeepkumar/sumo/ $] cd sumo/tools $] python osmWebWizard.py Once the data generated $] sumo -c osm.sumocfg --fcd-output trace.xml sumo has a traceExporter.py file, this file has to be processed. $] python traceExporter.py -i 2019-08-18-20-47-08/trace.xml --ns2mobility-output=/home/pradeepkumar/mobility.tcl from the mobility.tcl file,there are 32 nodes (vehicles) and 249 seconds Step 2: NS3 part Copy the file vanet-routing-compare.cc file to the scratch folder. $] cp ns-allinone-3.27/ns-3.27/src/wave/examples/vanet-routing-compare.cc ns-allinone-3.27/ns-3.27/scratch/ Do the modifications in line numbe 2392 as indicated in the video My simulation will be running for various protocols like OLSR, AODV and DSDV Scenario 2 is used for Selaiyur, Tambaram, Chennai, India Total time is 30 seconds Vehicle movement is 20m/s $] ./waf --run "scratch/vanet-routing-compare --protocol=1 --scenario=2" 1 - OLSR 2- AODV 3- DSDV 4. DSR To process the results, we used gnuplot and LibreOFfice Spreadsheet Gnuplot Code. set terminal pdf set output "RR.pdf" set title "Receive Rate" set xlabel "Simulation Time (Seconds)" set ylabel "Receive Rate" plot "AODV.csv" using 1:2 with linespoints title "AODV", "OLSR.csv" using 1:2 with linespoints title "OLSR","DSDV.csv" using 1:2 with linespoints title "DSDV","DSR.csv" using 1:2 with linespoints title "DSR" set terminal pdf set output "PR.pdf" set title "Packets Receives" set xlabel "Simulation Time (Seconds)" set ylabel "PAckets Received" plot "AODV.csv" using 1:3 with linespoints title "AODV", "OLSR.csv" using 1:3 with linespoints title "OLSR","DSDV.csv" using 1:3 with linespoints title "DSDV","DSR.csv" using 1:3 with linespoints title "DSR" set terminal pdf set output "macphy.pdf" set title "Mac Phy OVerhead" set xlabel "Simulation Time (Seconds)" set ylabel "Overhead" plot "AODV.csv" using 1:22 with linespoints title "AODV", "OLSR.csv" using 1:22 with linespoints title "OLSR","DSDV.csv" using 1:22 with linespoints title "DSDV","DSR.csv" using 1:22 with linespoints title "DSR" WE have done the basic simulations.. and plotting of characteristics. Similar way , we can do it for other results also. In the next video, I will be showcasing how to use flowmonitor for plotting the various losses, bitrates in the system or network. python scripts to read the flowmonitors.
