To Simulate DSR Protocol Projects Using NS3 all you have to do is share with us all the research details you have by mail we will reply you immediately, get valuable and best outcomes from us. We have all the tools and resources to aid you in your work. without any hesitation you can approach us talk with pour experts to clarify your doubts. To simulate the DSR (Dynamic Source Routing) protocol within NS3, we follow these steps:
Steps to Simulate DSR Protocol Projects in NS3
- Install NS3
Make sure NS3 is installed on the computer. Unless, we download it from the NS3 official website and we follow the installation guide for the operating system.
- Check for DSR in NS3
NS3 contains the DSR as portion of the ad-hoc routing protocols. Thus, we don’t require to execute it from scratch. We just require to set up the simulation to utilise DSR.
- Create or Modify a Simulation Script
We can utilise the NS3 instance scripts or we make a new one. Then we follow these steps within the script to simulate DSR.
- Steps to Simulate DSR in NS3
- Include Necessary Headers:
We can require to consist of the suitable headers for DSR, mobility, and the network stack.
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/internet-module.h”
#include “ns3/dsr-module.h”
#include “ns3/mobility-module.h”
#include “ns3/wifi-module.h”
#include “ns3/netanim-module.h”
- Set Up Nodes and Network:
Now, make the nodes and install the DSR routing protocol on them.
NodeContainer nodes;
nodes.Create(5); // Create 5 nodes
// Set up Wifi devices
WifiHelper wifi;
wifi.SetStandard(WIFI_PHY_STANDARD_80211g);
WifiMacHelper wifiMac;
YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default();
YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default();
wifiPhy.SetChannel(wifiChannel.Create());
// Set ad-hoc wifi MAC protocol
wifiMac.SetType(“ns3::AdhocWifiMac”);
NetDeviceContainer devices = wifi.Install(wifiPhy, wifiMac, nodes);
// Install the Internet stack with DSR
InternetStackHelper stack;
DsrMainHelper dsrMainHelper;
DsrHelper dsrHelper;
stack.Install(nodes);
dsrMainHelper.Install(dsrHelper, nodes);
- Assign IP Addresses:
Allocate an IP addresses to the network interfaces of the nodes.
Ipv4AddressHelper ipv4;
ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = ipv4.Assign(devices);
- Configure Mobility:
Set the mobility model for the nodes that ascertains how the nodes are move.
MobilityHelper mobility;
mobility.SetPositionAllocator(“ns3::GridPositionAllocator”,
“MinX”, DoubleValue(0.0),
“MinY”, DoubleValue(0.0),
“DeltaX”, DoubleValue(5.0),
“DeltaY”, DoubleValue(10.0),
“GridWidth”, UintegerValue(3),
“LayoutType”, StringValue(“RowFirst”));
mobility.SetMobilityModel(“ns3::ConstantPositionMobilityModel”);
mobility.Install(nodes);
Also, we can utilise other mobility models such as RandomWaypointMobilityModel for dynamic movement.
- Set Up Traffic Generation:
Insert the traffic generation to analyse the routing protocol’s performance. Now, we use UDP Echo applications to generate traffic.
UdpEchoServerHelper echoServer(9); // Port 9
ApplicationContainer serverApps = echoServer.Install(nodes.Get(1)); // Install server on node 1
serverApps.Start(Seconds(1.0));
serverApps.Stop(Seconds(10.0));
UdpEchoClientHelper echoClient(interfaces.GetAddress(1), 9); // Server IP and port
echoClient.SetAttribute(“MaxPackets”, UintegerValue(1));
echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));
echoClient.SetAttribute(“PacketSize”, UintegerValue(1024));
ApplicationContainer clientApps = echoClient.Install(nodes.Get(0)); // Install client on node 0
clientApps.Start(Seconds(2.0));
clientApps.Stop(Seconds(10.0));
- Run Simulation:
We can use the following commands to run the simulation and investigate outcomes.
Simulator::Stop(Seconds(10.0));
Simulator::Run();
Simulator::Destroy();
- Optional: Add Animation:
If we need to envision the simulation then we can use NetAnim to generate an animation file.
AnimationInterface anim(“dsr_simulation.xml”); // Creates animation file
- Run the Simulation
After making the script then we compile and run it using waf:
./waf build
./waf –run <your_script>
- Analyze the Results
We can be investigated parameters such as packet delivery ratio, delay, or routing overhead. Also wee may generate trace files for further analysis using tools such as Wireshark.

This script configures a simple DSR protocol simulation in NS3. We can be extended and changed it based on the project requirements.
We performed a structured procedure on DSR Protocol projects, employing the simulation tool ns3 for its replicated and analysed. If you require, more comprehensive details we will be provided.
