How to Start Optical Communication Projects Using NS3

To start the optical communication projects using NS3 which encompasses to replicate the high-speed data transmission to utilise light waves that frequently offered as fiber-optic or free-space optical interaction. While NS3 doesn’t directly support advanced optimal communication models such as those in specialized optimal network simulators, it allows to emulate the high data rates and distinct optical communication’s features to use customized configurations or third-party extensions. This guide provides steps to configure a simple optical communication simulation in NS3, concentrating on either fiber-optic or free-space optical networks.

Steps to Start Optical Communication Projects in NS3

  1. Install NS3
  1. Download and Install NS3:

git clone https://gitlab.com/nsnam/ns-3-dev.git ns-3

cd ns-3

./waf configure –enable-examples –enable-tests

./waf build

  1. Verify Installation: Execute a basic instance like a point-to-point example, verifying NS3 is properly functioning:

./waf –run=point-to-point

  1. Choose a Communication Model (Fiber or Free-Space)

Optical communication can replicate, for wired communication either with fiber-optic channels or free-space optical channels for wireless optical interaction.

  • Fiber-Optic Communication: Design fiber-optic networks utilising high-data-rate point-to-point links of NS3. We can configure the high data rates and low delays to estimate the fiber characteristics.
  • Free-Space Optical (FSO) Communication: Utilize a custom point-to-point link set up, we can design the FSO links to deliberate the unique propagation impacts such as atmospheric loss, alignment, and line-of-sight (LOS) needs.
  1. Set Up a Basic Optical Network Topology

Here’s is a instance that illustrates how to make a basic fiber-optic communication link in which two nodes interact through a high-speed optical link to utilize NS-3’s point-to-point module.

Example: Fiber-Optic Link with High Data Rate

This instance configurations a basic network in which two nodes interact through a fiber-optic channel.

#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 two nodes representing the sender and receiver

NodeContainer nodes;

nodes.Create(2);

// Set up a point-to-point link to represent the fiber-optic channel

PointToPointHelper pointToPoint;

pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“10Gbps”)); // High data rate for optical link

pointToPoint.SetChannelAttribute(“Delay”, StringValue(“1ms”)); // Low latency to simulate fiber

NetDeviceContainer devices;

devices = pointToPoint.Install(nodes);

// Install the Internet stack

InternetStackHelper stack;

stack.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper address;

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

Ipv4InterfaceContainer interfaces = address.Assign(devices);

// Set up an application: A UDP echo server on the receiving node

uint16_t port = 9;

UdpEchoServerHelper echoServer(port);

ApplicationContainer serverApp = echoServer.Install(nodes.Get(1)); // Receiver

serverApp.Start(Seconds(1.0));

serverApp.Stop(Seconds(10.0));

// Set up a UDP echo client on the sender node

UdpEchoClientHelper echoClient(interfaces.GetAddress(1), port);

echoClient.SetAttribute(“MaxPackets”, UintegerValue(100));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(0.1)));

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

ApplicationContainer clientApp = echoClient.Install(nodes.Get(0)); // Sender

clientApp.Start(Seconds(2.0));

clientApp.Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

}

  1. Customize Optical Channel Properties

To improve the optical communication replication, change the channel properties like data rate, latency, and error rate:

  • Data Rate: Optical links frequently uses rates from 10 Gbps up to numerous Tbps. Change the DataRate attribute deliberating it.
  • Delay: Configure a low delay like 1 ms to signify the speed of light within fiber and modify if designing a longer fiber span including several repeaters.
  • Error Model: Optical links are normally reliable however can be impacted using noise, dispersion, and other factors. If designing these impacts then we can append an error model.

Example:

pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“100Gbps”)); // Set for high-rate optical transmission

pointToPoint.SetChannelAttribute(“Delay”, StringValue(“0.5ms”)); // Adjust to represent real fiber-optic delay

  1. Set Up Free-Space Optical Communication (Optional)

Modify the point-to-point link replicating more losses or interruptions because of the atmospheric conditions, alignment, or obstacles for free-space optical interaction.

Example adjustments:

  1. Line-of-Sight Constraints: In the connection, design interruptions replicating the line-of-sight needs.
  2. Atmospheric Loss: Utilize a custom loss model mimicking atmospheric attenuation like fog, rain.
  3. Error Model: Set up an error model denoting the data corruption triggered by atmospheric disturbances.
  1. Implement Applications to Simulate Optical Traffic

Replicate the data transmission utilizing NS3 applications such as OnOffApplication or BulkSendApplication. High-throughput applications can be replicated the traffic demands at an optical link.

Example:

OnOffHelper onOff(“ns3::UdpSocketFactory”, InetSocketAddress(interfaces.GetAddress(1), port));

onOff.SetAttribute(“DataRate”, StringValue(“5Gbps”)); // High data rate traffic

onOff.SetAttribute(“PacketSize”, UintegerValue(1500));

ApplicationContainer onOffApp = onOff.Install(nodes.Get(0));

onOffApp.Start(Seconds(2.0));

onOffApp.Stop(Seconds(10.0));

  1. Collect and Analyze Performance Metrics

In optical communication, we can examine the crucial performance parameters contain:

  • Throughput: Estimate the data rate over the optical link.
  • Latency: Verify latency for low delay that particularly across long distances.
  • Packet Loss: Make sure reliable interaction and if we insert an error model, loss may happen to replicate the channel impairments.

Use FlowMonitor to gather performance data:

FlowMonitorHelper flowmon;

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

monitor->SerializeToXmlFile(“optical-flowmon.xml”, true, true);

  1. Visualize and Analyze Results
  • NetAnim: Envision data flows via it probably more helpful for common network visualization instead of in-depth optical impacts to utilize NetAnim.
  • Trace Files: Consider trace files examining the packet transmission, reception, and delays.
  • Graphing Tools: Tranfer data to graph parameters such as throughput and latency which is particularly for estimating the performance in diverse channel conditions.
  1. Experiment with Advanced Optical Network Scenarios

After configuring the simple network then we discover more situations:

  • Multi-Hop Optical Networks: Replicate an optical backbone including intermediate nodes utilizing several point-to-point links.
  • Wavelength Division Multiplexing (WDM): Mimic several data channels across a single fiber by means of setting up distinct data flows along with unique properties.
  • Free-Space Optical Relays: Configure relay nodes replicating the multi-hop free-space optical networks in which each hop can be impacted through alignment or environmental conditions.
