We have all of the tools and resources you need to complete your work. You can approach us without hesitation and speak with one of our experts to clear your doubts.
Steps to Simulate DSDV Protocol Projects in NS3
- Install NS3
- Make sure that NS3 is installed on the system. We can download it from the NS3 official website. Then we follow the installation guidelines particular to the operating system (Linux, macOS, or Windows).
- Check for DSDV in NS3
NS3 contains an execution of the DSDV routing protocol, thus we don’t require to execute this from the scratch. Just we can want to set the simulation to use DSDV.
- Create or Modify a Simulation Script
We can use an existing NS3 instance or make own simulation script. Below is an overview of the steps to follow in the script.
- Steps to Setup DSDV in NS3
- Include Necessary Headers: We will want to contain the essential headers for DSDV, internet stack, and mobility. The followings are some examples of headers to contain:
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/internet-module.h”
#include “ns3/dsdv-helper.h”
#include “ns3/mobility-module.h”
- Set Up Nodes and Network: We will require to make a nodes and configure the network, installing the internet stack and DSDV routing protocol.
// Create nodes
NodeContainer nodes;
nodes.Create(5); // Change this to the number of nodes you need
// Install Internet stack with DSDV
InternetStackHelper internet;
DsdvHelper dsdv;
internet.SetRoutingHelper(dsdv); // Install DSDV
internet.Install(nodes);
- Assign IP Addresses: Allocate an IP addresses to the devices are attached to nodes.
// Setup the network devices
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“5Mbps”));
pointToPoint.SetChannelAttribute(“Delay”, StringValue(“2ms”));
NetDeviceContainer devices;
devices = pointToPoint.Install(nodes.Get(0), nodes.Get(1));
// Install IP addresses
Ipv4AddressHelper address;
address.SetBase(“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign(devices);
- Setup Mobility Model: We can be described how the nodes will move if we require a mobile ad-hoc network (MANET) simulation.
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::RandomWalk2dMobilityModel”,
“Bounds”, RectangleValue(Rectangle(-50, 50, -50, 50)));
mobility.Install(nodes);
- Applications (Traffic Generation): Install some applications such as UDP or TCP traffic to analyse the network performance.
UdpEchoServerHelper echoServer(9);
ApplicationContainer serverApps = echoServer.Install(nodes.Get(1));
serverApps.Start(Seconds(1.0));
serverApps.Stop(Seconds(10.0));
UdpEchoClientHelper echoClient(interfaces.GetAddress(1), 9);
echoClient.SetAttribute(“MaxPackets”, UintegerValue(1));
echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));
echoClient.SetAttribute(“PacketSize”, UintegerValue(1024));
ApplicationContainer clientApps = echoClient.Install(nodes.Get(0));
clientApps.Start(Seconds(2.0));
clientApps.Stop(Seconds(10.0));
- Run Simulation:
Simulator::Run();
Simulator::Destroy();
- Run the Simulation
- After writing the simulation script, then we compile it using waf:
./waf build
./waf –run <your_script>
- Analyze Output
- NS3 will generate simulation outcomes that we can examine to measure the performance of the DSDV protocol. We can use numerous parameters such as packet delivery ratio, latency, or throughput for performance analysis.
- Optional: Visualization
- For a better understanding of node movements and packet flows, we can utilise the NetAnim to envision the simulation.
Example Full Script
The following is a basic example of an NS3 script using DSDV:
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/internet-module.h”
#include “ns3/dsdv-helper.h”
#include “ns3/mobility-module.h”
#include “ns3/netanim-module.h”
#include “ns3/point-to-point-module.h”
#include “ns3/applications-module.h”
using namespace ns3;
int main(int argc, char *argv[]) {
NodeContainer nodes;
nodes.Create(5); // Create 5 nodes
// Install the Internet stack with DSDV routing protocol
DsdvHelper dsdv;
InternetStackHelper internet;
internet.SetRoutingHelper(dsdv);
internet.Install(nodes);
// Create and assign IP addresses
PointToPointHelper p2p;
p2p.SetDeviceAttribute(“DataRate”, StringValue(“5Mbps”));
p2p.SetChannelAttribute(“Delay”, StringValue(“2ms”));
NetDeviceContainer devices;
devices = p2p.Install(nodes.Get(0), nodes.Get(1));
Ipv4AddressHelper address;
address.SetBase(“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign(devices);
// Set mobility for nodes
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::RandomWalk2dMobilityModel”,
“Bounds”, RectangleValue(Rectangle(-50, 50, -50, 50)));
mobility.Install(nodes);
// Set up traffic (UDP Echo Application)
UdpEchoServerHelper echoServer(9);
ApplicationContainer serverApps = echoServer.Install(nodes.Get(1));
serverApps.Start(Seconds(1.0));
serverApps.Stop(Seconds(10.0));
UdpEchoClientHelper echoClient(interfaces.GetAddress(1), 9);
echoClient.SetAttribute(“MaxPackets”, UintegerValue(1));
echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));
echoClient.SetAttribute(“PacketSize”, UintegerValue(1024));
ApplicationContainer clientApps = echoClient.Install(nodes.Get(0));
clientApps.Start(Seconds(2.0));
clientApps.Stop(Seconds(10.0));
// Run the simulation
Simulator::Run();
Simulator::Destroy();
return 0;
}
It should give a simple configuration to replicate the DSDV in NS3. We can alter and extend this instance according to the project’s requirements.
As expounded above, we understood how to replicate and investigate the DSDV protocol projects through the above simplified instructions using NS3 simulation environment. Additional specific insights related to this protocol we will be offered in upcoming material.
