How to Start FASTEST Protocol Projects Using NS3

To start a FASTEST protocol project using NS3, we will need to describe what “FASTEST” refers to in the scenario. If we are executing or replicating a high-performance protocol such as low-latency routing, fast data dissemination, or a novel network optimization protocol then NS3 environment can support the project goals. Here’s a basic guide to start a project for making or replicating a “fastest” protocol:

Steps to Start FASTEST Protocol Projects in NS3

  1. Define the Objective
  • Clarify the Protocol:
    • We can define “FASTEST” refers in the context. Instances may contain:
      • Low-latency routing protocols.
      • High-throughput MAC layer protocols.
      • Optimized transport protocols (e.g., congestion control).
      • Fast packet dissemination in DTNs or MANETs.
  • Focus Area:
    • Application Layer: It helps fast content delivery or data transfer.
    • Transport Layer: It supports high-speed TCP/UDP variants.
    • Network Layer: It is used in low-latency routing or shortest path algorithms.
    • MAC/PHY Layer: Optimized medium access mechanisms.
  1. Set Up NS3
  • Install NS3:
    • Go to nsnam.org, we download and install NS3.
  • Verify Installation:

./waf –run scratch/test-example

  • Modules to Use:
    • internet: These modules supports IP routing and transport protocols.
    • wifi, csma: It is helps for wireless or wired networks.
    • mobility: For dynamic node movement as valid.
    • traffic-control: For QoS or congestion control replciations.
  1. Plan the Protocol Design
  • Identify Protocol Characteristics:
    • Low Latency: We model the routing or transport mechanisms, which give precedence to low delays.
    • High Throughput: It enhances the bandwidth utilization.
    • Reliability vs Speed Trade-off: It scales the speed and reliability for certain situations.
  • Metrics to Evaluate:
    • We need to measure the performance indicators including end-to-end latency, throughput (packets/sec or bits/sec), and packet delivery ratio.
  1. Write a Basic Simulation Script
  • We can begin with a basic wired or wireless network configuration to experiment the ideas.
  • Example: High-Speed UDP Communication

#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[]) {

CommandLine cmd;

cmd.Parse(argc, argv);

// Create nodes

NodeContainer nodes;

nodes.Create(2);

// Create point-to-point links

PointToPointHelper p2p;

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

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

NetDeviceContainer devices = p2p.Install(nodes);

// Install Internet stack

InternetStackHelper stack;

stack.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper ipv4;

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

Ipv4InterfaceContainer interfaces = ipv4.Assign(devices);

// Create UDP server on Node 1

uint16_t port = 9;

UdpServerHelper server(port);

ApplicationContainer serverApps = server.Install(nodes.Get(1));

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

// Create UDP client on Node 0

UdpClientHelper client(interfaces.GetAddress(1), port);

client.SetAttribute(“MaxPackets”, UintegerValue(10000));

client.SetAttribute(“Interval”, TimeValue(Seconds(0.0001))); // 10,000 packets/sec

client.SetAttribute(“PacketSize”, UintegerValue(1024));

ApplicationContainer clientApps = client.Install(nodes.Get(0));

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

// Enable pcap tracing

p2p.EnablePcapAll(“fastest-protocol”);

Simulator::Run();

Simulator::Destroy();

return 0;

}

  1. Customize the Protocol
  • Custom Layer Implementation:
    • Application Layer: Execute the custom applications for rapid data dissemination.
    • Transport Layer: We can change or make congestion control mechanisms such as FAST TCP, QUIC.
    • Network Layer: It executes the shortest path or low-latency routing.
    • MAC Layer: Enhance the medium access like TDMA, dynamic slot allocation.
  • Extend NS3 Classes:
    • Make use of Ipv4RoutingProtocol for network-layer customization.
    • For transport-layer improvements, utilise TcpSocketBase.
    • Use NetDevice for link-layer optimizations.
  1. Test and Debug
  • Enable Logging:

export NS_LOG=UdpClientApplication=level_all

./waf –run scratch/fastest-protocol

  • Use Tracing:
    • Utilzie PCAP files in Wireshark to inspect the packet flow.
  • Verify Performance:
    • Insert logs estimating the packet delivery times and throughput.
  1. Evaluate Performance
  • Metrics to Measure:
    • Throughput: We need to compute the volume of packets/bytes that are distributed for each second.
    • Latency: Measure how long it takes time for a packet to pass through the network.
    • Packet Loss Ratio: Estimate the ratio of packets that are lost in the course of transmission.
  • Tools:
    • For end-to-end statistics, we can utilise FlowMonitor:

FlowMonitorHelper flowMonitor;

Ptr<FlowMonitor> monitor = flowMonitor.InstallAll();

    • Envision packet delivery and delays utilising NetAnim.
  1. Advanced Features
  • Dynamic Topologies:
    • Insert mobility models for nodes within wireless environments.
  • Energy Awareness:
    • Contain energy models, replicating the power-efficient protocols.
  • Optimized Routing:
    • We execute load balancing or multi-path routing mechanisms for optimize routing.
  • Traffic Control:
    • Launch QoS mechanisms to give precedence traffic classes.
