How to Start Route Source Protocol Projects Using NS3

To start a Route Source Protocol (RSP) project in NS3 which requires replicating or executing a routing protocol in which the route source like a predefined node or central controller performs as a crucial role within route determination and distribution. It is frequently utilized in dynamic or policy-based routing situations with Software-Defined Networking (SDN), ad-hoc networks, or custom routing protocols.

Below is a common method to get started the Route Source Protocol project using NS3.

Steps to Start Route Source Protocol Project in NS3

  1. Understand Route Source Protocol Concepts
  • What is a Route Source Protocol?
    • A routing mechanism in which the source node or a centralized controller computes and handles the routing paths.
    • Examples:
      • Predefined static routes configured by the source.
      • According to the network conditions, dynamic routes updated.
  • Common Use Cases:
    • Centralized routing within SDN.
    • Ad-hoc routing protocols in MANETs such as AODV, DSR.
    • Depends on the policies or network parameters, custom routing.
  1. Set Up NS3
  • Install NS3:
    • Go to nsnam.org to download and install NS3 on the system.
  • Verify installation:

./waf –run scratch/test-example

  • Modules to Enable:
    • internet: It supports for IP stack and routing.
    • point-to-point or csma: For replicating the wired links.
    • mobility (if operating with mobile or dynamic topologies).
  1. Plan Your Protocol Implementation
  • Define the Protocol Logic:
    • We can describe the static or dynamic route determination on source node.
    • Mechanism for distributing routes such as flooding and periodic updates.
  • Define Objectives:
    • Measure the performance metrics like latency, throughput.
    • Enhance routing decisions for certain parameters such as shortest path, QoS.
  • Topology:
    • We can select a network topology such as linear, star, mesh depends on the use case.
  1. Write a Basic Routing Simulation
  • We can write simplified NS3 routing configuration.
  • Example: Static Routing Using a Route Source

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/point-to-point-module.h”

#include “ns3/applications-module.h”

using namespace ns3;

int main(int argc, char *argv[]) {

// Create nodes

NodeContainer nodes;

nodes.Create(4); // Create 4 nodes

// Create point-to-point links

PointToPointHelper p2p;

p2p.SetDeviceAttribute(“DataRate”, StringValue(“10Mbps”));

p2p.SetChannelAttribute(“Delay”, StringValue(“2ms”));

NetDeviceContainer devices1 = p2p.Install(nodes.Get(0), nodes.Get(1));

NetDeviceContainer devices2 = p2p.Install(nodes.Get(1), nodes.Get(2));

NetDeviceContainer devices3 = p2p.Install(nodes.Get(2), nodes.Get(3));

// Install Internet stack

InternetStackHelper internet;

internet.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper ipv4;

ipv4.SetBase(“10.1.1.0”, “255.255.255.0”);

Ipv4InterfaceContainer interfaces1 = ipv4.Assign(devices1);

ipv4.SetBase(“10.1.2.0”, “255.255.255.0”);

Ipv4InterfaceContainer interfaces2 = ipv4.Assign(devices2);

ipv4.SetBase(“10.1.3.0”, “255.255.255.0”);

Ipv4InterfaceContainer interfaces3 = ipv4.Assign(devices3);

// Configure static routing at the source

Ptr<Ipv4StaticRouting> staticRouting = Ipv4RoutingHelper::GetRouting<Ipv4StaticRouting>(nodes.Get(0)->GetObject<Ipv4>());

staticRouting->AddNetworkRouteTo(Ipv4Address(“10.1.3.0”), Ipv4Mask(“255.255.255.0”), Ipv4Address(“10.1.1.2”), 1);

// Set up a UDP Echo Server on the last node

uint16_t port = 9;

UdpEchoServerHelper echoServer(port);

ApplicationContainer serverApps = echoServer.Install(nodes.Get(3));

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

// Set up a UDP Echo Client on the source node

UdpEchoClientHelper echoClient(Ipv4Address(“10.1.3.1”), port);

echoClient.SetAttribute(“MaxPackets”, UintegerValue(5));

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));

// Enable pcap tracing

p2p.EnablePcapAll(“route-source”);

Simulator::Run();

Simulator::Destroy();

return 0;

  1. Implement Route Source Protocol Logic
  • Custom Routing Logic:
    • Prolong Ipv4RoutingProtocol, making the custom routing protocol.
    • Override techniques such as:
      • RouteInput(): We try to find how incoming packets are routed.
      • RouteOutput(): We configure outgoing routes rely on source policies.
  • Centralized Source Node Logic:
    • Dynamically modernize routing tables to utilize callbacks or message exchanges.
  1. Test and Debug
  • Enable Logging:

export NS_LOG=Ipv4RoutingProtocol=level_all

./waf –run scratch/route-source

  • Analyze Traffic:
    • For packet inspection utilise PCAP files within Wireshark.
    • We need to utilize FlowMonitor for metrics like throughput, latency, and other parameters.
  1. Analyze Performance
  • Metrics to Measure:
    • We compute the performance indicators such as packet delivery ratio, end-to-end latency, and routing overhead like control message size and frequency.
  • We accumulate parameters using NS3 tools such as FlowMonitor or custom callbacks.
  1. Advanced Features
  • Dynamic Routing:
    • Fine-tune the route source, adapting the routes according to the following:
      • Link failures.
      • Traffic conditions.
  • Policy-Based Routing:
    • We describe policies for routing decisions such as QoS, shortest path.
  • Security Features:
    • For route advertisements, we insert encryption or authentication mechanisms.
  • Scalability Testing:
    • Maximize the volume of nodes and routes estimating the performance in load.
  1. Documentation and Visualization
  • Document:
    • It provides protocol details, simulation configuration, and performance outcomes.
  • Visualize Results:
    • For topology and traffic visualization, we can utilize NetAnim.
    • We need to graph the performance parameters using tools like Matplotlib or Gnuplot.
