#AODV #OLSR #MANETs #DSDV #DSR • Download the Code here: • https://drive.google.com/open?id=1OkV... • Comparison of MANET routing Protocols • 1. AODV • 2. DSDV • 3. DSR • 4. OLSR • using NS3 (Network Simulator 3) • B.Tech, M.Tech, PhD... • 1. Reactive Vs Proactive routing • 2. PErformance comparison of MANET protocols • 3. AODV Vs DSDV Comparison • https://www.nsnam.com • and also at my channel. • What Version: ns-3.29, ns-3.28,3.27,3.26,.... • My Ubunut OS is: Ubuntu 18.04 • This file we are going to use for our simulation: • /home/networks/ns-allinone-3.29/ns-3.29/examples/routing/manet-routing-compare.cc • • Once you under stand the code, now lets run this example • • Step 1: Copy the above file in to ~ns-3.29/scratch/ folder • Step 2: Understand this code. • Step 3: Run this code • Open the terminal, Go to ns-3.29 and run the following command • ./waf --run scratch/manet-routing-compare • enable the following header file • #include ns3/flow-monitor-helper.h • four files got generated • AODV.csv • AODV.mob • AODV.flomon • temp.data • Parameters: • Number of nodes: 50 • No of sinks : 10 • Mobility Model: • Propagation Model: ConstantSpeedPropagationDelay • Propagation Loss Model: Friis • Position Allocator: RandomRectangularPositionAllocator • Mac: AdhocWifiMAC • Mac Standard: 802.11B • Bps: 2Kbps • Total Simulation Time: 200 seconds • Node speed: 20m/s • Node pause time: 0 • Protocol: AODV • • To run the flowmon file, use of temp.py is advised. • to run the file, use the following • $] python flow.py AODV.flowmon • Find the python script here. • #beginning of Script • from xml.etree import ElementTree as ET • import sys • import matplotlib.pyplot as pylab • et=ET.parse(sys.argv[1]) • bitrates=[] • losses=[] • delays=[] • for flow in et.findall( FlowStats/Flow ): • for tpl in et.findall( Ipv4FlowClassifier/Flow ): • if tpl.get('flowId')==flow.get('flowId'): • break • if tpl.get('destinationPort')=='654': • continue • losses.append(int(flow.get('lostPackets'))) • • rxPackets=int(flow.get('rxPackets')) • if rxPackets==0: • bitrates.append(0) • else: • t0=float(flow.get('timeFirstRxPacket')[:-2]) • t1=float(flow.get( timeLastRxPacket )[:-2]) • duration=(t1-t0)*1e-9 • bitrates.append(8*long(flow.get( rxBytes ))/duration*1e-3) • delays.append(float(flow.get('delaySum')[:-2])*1e-9/rxPackets) • pylab.subplot(311) • pylab.hist(bitrates,bins=40) • pylab.xlabel( Flow Bit Rates (b/s) ) • pylab.ylabel( Number of Flows ) • • pylab.subplot(312) • pylab.hist(bitrates,bins=40) • pylab.xlabel( No of Lost Packets ) • pylab.ylabel( Number of Flows ) • pylab.subplot(313) • pylab.hist(bitrates,bins=10) • pylab.xlabel( Delay in Seconds ) • pylab.ylabel( Number of Flows ) • pylab.subplots_adjust(hspace=0.4) • pylab.savefig( results.pdf ) • #End of Script • We can plot using gnuplot (through CSV File) and matplotlib(Flow monitor) • All these examples, runs for 50 nodes • whenever you compare protocols,have three different sets of node numbers • 10 nodes, 50 nodes, 100 nodes and compare them with various metrics as mentioned above... • To analsyse .tr files, we need to use tracemetrics • its a jar file that can be run using • $] java -jar tracemetrics.jar • • Hope you would have got an idea on how to simulate wireless protocols using ns3. • Download the source code through my blog www.nsnam.com • and also subscribe to my channel and share it to your friends/colleaques.
