How to Start Telecommunication Projects Using NS3

To start the telecommunication projects using NS3 which contains to replicate diverse features of interaction networks for data transmission, routing, and network management like mobile networks (LTE, 5G), WiFi networks, wired connections, and protocols. NS3 offers flexibility to construct, configuring and to estimate a broad range of telecommunications situations from mobile communication to wired and wireless networking.

Below is a basic procedure in order to initiate with common telecommunication projects in NS3:

Steps to Start Telecommunication Projects in NS3

  1. Install NS3 and Required Modules

Make certain that we have installed NS3 on the system including the essential modules for project like LTE, WiFi, and Ethernet.

  1. Download and Install NS3 (if doesn’t already done).

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: Confirm that, from NS3 we can execute the simple instances making sure that the installation was effective.

./waf –run=hello-simulator

  1. Understand Telecommunication Project Components

Telecommunication projects might include one or more of the following basics:

  • Network Types: It contains wired (Ethernet) and wireless (WiFi, LTE, and 5G) networks.
  • Traffic Types: Make diverse kinds of traffic like VoIP, video streaming, file transfer, or web browsing.
  • Protocols: We execute the diverse protocols such as TCP, UDP, ICMP, and so on, to replicate real-world network interaction.
  • Network Topologies: Signify diverse network architectures to configure simple to complex topologies like star, mesh, tree, ring.
  1. Create a Basic Telecommunication Network Topology

Initially, we make a basic network to know the NS3’s basics. Following is a simple instance along with Ethernet and WiFi replicating the wired and wireless connections.

Example: Wired and Wireless Telecommunication Network

  1. Define the Nodes: Make nodes to signify devices such as clients, routers, servers.
  2. Set Up Wired and Wireless Connections: For wired communication, we can utilize Ethernet and WiFi for wireless interaction.
  3. Configure IP Addressing and Routing: Allocate an IP addresses and then configure routing among the nodes.

Below is a simple NS3 script making a hybrid network including Ethernet and WiFi connections:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/mobility-module.h”

#include “ns3/internet-module.h”

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

#include “ns3/wifi-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 p2pNodes;

p2pNodes.Create(2); // Server and Router

NodeContainer wifiStaNodes;

wifiStaNodes.Create(2); // Two client devices

NodeContainer wifiApNode = p2pNodes.Get(1); // Router will act as WiFi AP

// Set up Point-to-Point (P2P) connection between server and router

PointToPointHelper p2p;

p2p.SetDeviceAttribute(“DataRate”, StringValue(“100Mbps”));

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

NetDeviceContainer p2pDevices = p2p.Install(p2pNodes);

// Set up WiFi (802.11n) between router (AP) and clients

WifiHelper wifi;

wifi.SetStandard(WIFI_PHY_STANDARD_80211n_5GHZ);

YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default();

YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default();

wifiPhy.SetChannel(wifiChannel.Create());

WifiMacHelper wifiMac;

Ssid ssid = Ssid(“ns3-wifi”);

wifiMac.SetType(“ns3::StaWifiMac”, “Ssid”, SsidValue(ssid));

NetDeviceContainer staDevices = wifi.Install(wifiPhy, wifiMac, wifiStaNodes);

wifiMac.SetType(“ns3::ApWifiMac”, “Ssid”, SsidValue(ssid));

NetDeviceContainer apDevices = wifi.Install(wifiPhy, wifiMac, wifiApNode);

// Install the Internet stack

InternetStackHelper stack;

stack.Install(p2pNodes);

stack.Install(wifiStaNodes);

// Assign IP addresses to each network interface

Ipv4AddressHelper address;

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

Ipv4InterfaceContainer p2pInterfaces = address.Assign(p2pDevices);

address.SetBase(“192.168.1.0”, “255.255.255.0”);

address.Assign(staDevices);

address.Assign(apDevices);

// Set up applications (e.g., UDP echo)

UdpEchoServerHelper echoServer(9); // Port 9

ApplicationContainer serverApp = echoServer.Install(p2pNodes.Get(0)); // Server node

serverApp.Start(Seconds(1.0));

serverApp.Stop(Seconds(10.0));

UdpEchoClientHelper echoClient(p2pInterfaces.GetAddress(0), 9); // Server IP

echoClient.SetAttribute(“MaxPackets”, UintegerValue(10));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));

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

ApplicationContainer clientApps = echoClient.Install(wifiStaNodes.Get(0)); // First client device

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

// Mobility for WiFi 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, -25, 50)));

mobility.Install(wifiStaNodes);

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

}

  1. Add More Complexity and Realistic Features

When we have a simple configuration then append more aspects creating the simulation more realistic and then modified to certain telecommunication situations:

Mobility

  • Replicate moving clients to utilize the mobility models such as RandomWaypointMobilityModel, ConstantVelocityMobilityModel, and so on.
  • It is helpful specifically for mobile network simulations like LTE or 5G.

Quality of Service (QoS)

  • For applications, execute the QoS settings by means of setting up traffic classes within LTE or WiFi.
  • We replicate diverse kinds of traffic such as VoIP (low latency), video streaming (high bandwidth), and background data (lower priority).

Routing Protocols

  • Insert routing protocols for larger networks, such as OLSR, AODV, or DSDV for dynamic routing.
  1. Collect Performance Metrics

Gather crucial network parameters utilizing NS3’s tracing and observing tools, which containing:

  • Throughput: Data rate across each network segment.
  • Latency: End-to-end delay.
  • Packet Loss: Estimate the packet drops that is particularly in load or mobility.
  • Jitter: Monitor variations within packet arrival time, which is vital for real-time applications.

Example using FlowMonitor:

FlowMonitorHelper flowmon;

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

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

  1. Experiment with Different Network Configurations

Testing with diverse metrics that supports to replicate diverse situations:

  • Increase Network Load: Replicate additional users, higher data rates, or distinct application types.
  • Network Conditions: Modify data rates, delays, or launch packet loss replicating real-world challenges.
  • Topology Variations: Experiment diverse topologies such as mesh, ring, and tree and learn the influence over performance.
  1. Visualize and Analyze Results
  • NetAnim: In real time, we can envision the topology, node movement, and packet exchanges using NetAnim tools.
  • Trace File Analysis: For in-depth analysis of network events and performance parameters utilizing trace files.
  • Custom Plots: Make plots of parameters such as throughput, latency, and packet loss over time to utilize data from trace files.
