How to Begin Implementing a Green Networking Projects in NS3

To begin executing a Green Networking project in NS3 encompasses to replicate energy-efficient network models, protocols, and strategies for reducing energy utilization whereas sustaining the suitable performance. Green networking addresses to enhance the energy use through network modules such as routers, switches, and end devices.

Below is a step-by-step instruction on how we can approach it:

Steps to Begin Implementing a Green Networking Projects in NS3

1. Understand Green Networking Concepts

• Key Principles:
  • Energy Efficiency: Reduce energy utilization within network devices.
  • Adaptive Resource Management: Adapt resources actively such as bandwidth, routing paths depends on the traffic.
  • Renewable Integration: For power network modules, we can utilize renewable energy sources.
• Common Use Cases:
  • Data center power optimization.
  • Sleep modes for idle devices.
  • Energy-aware routing.

2. Set Up NS3 Environment

• We should install and download the new version of NS3 on the system.
• Study these NS3 modules:
  • Energy Module: It is utilised for minimizing power consumption.
  • Internet Module: For TCP/IP interaction.
  • Applications Module: Making and handling the traffic models.

3. Define Project Objectives

• Following is a project’s goals of green networking:
  • Measure energy-efficient routing protocols.
  • Replicate sleep modes within idle routers or nodes.
  • Examine the trade-off among the energy savings and performance.

4. Design the Network Topology

• Nodes:
  • We make a network topology with nodes devices such as routers, switches, and end-user devices.
• Links:
  • Make use of Point-to-Point, Wi-Fi, or LTE connections for interaction.
• Traffic:
  • Create traffic for replicating the real-world scenarios in terms of web browsing or video streaming.

5. Incorporate the Energy Module

• Energy Source:
  • Connect energy models such as a simple energy source for mimicking battery or grid power.
• Device Models:
  • Monitor power usage to leverage WifiRadioEnergyModel or same device models.
• Example:

BasicEnergySourceHelper energySourceHelper;

energySourceHelper.Set(“BasicEnergySourceInitialEnergyJ”, DoubleValue(100.0));

EnergySourceContainer sources = energySourceHelper.Install(nodes);

WifiRadioEnergyModelHelper radioEnergyHelper;

radioEnergyHelper.Install(devices, sources);

6. Basic Green Networking Simulation

Below is a sample green networking simulation:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

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

#include “ns3/energy-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(3); // Two routers and one client

// Set up Point-to-Point links

PointToPointHelper p2p;

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

p2p.SetChannelAttribute(“Delay”, StringValue(“5ms”));

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

// Set up energy models

BasicEnergySourceHelper energySourceHelper;

energySourceHelper.Set(“BasicEnergySourceInitialEnergyJ”, DoubleValue(100.0));

EnergySourceContainer sources = energySourceHelper.Install(nodes);

WifiRadioEnergyModelHelper radioEnergyHelper;

DeviceEnergyModelContainer models = radioEnergyHelper.Install(devices, sources);

// Install Internet stack

InternetStackHelper stack;

stack.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper ipv4;

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

ipv4.Assign(devices);

// Create traffic generator

uint16_t port = 8080;

OnOffHelper onOff(“ns3::UdpSocketFactory”, InetSocketAddress(Ipv4Address(“10.1.1.2”), port));

onOff.SetAttribute(“DataRate”, StringValue(“1Mbps”));

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

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

apps.Start(Seconds(2.0));

apps.Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

}

7. Enhance the Simulation

• Dynamic Power Management:
  • For idle nodes or links, launch the sleep modes.
• Energy-Aware Routing:
  • Execute routing protocols, which give precedence to energy-efficient paths.
• Renewable Energy:
  • Mimic nodes that are powered by solar or wind energy.
• Traffic-Aware Policies:
  • Depends on traffic requests, adapt bandwidth or routing paths actively.

8. Performance Metrics

• Energy Consumption:
  • Estimate the energy utilization for each node or device.
• Network Lifetime:
  • Examine how long the network can be functioned by provided energy constraints.
• Throughput:
  • Measure the rate of data that are effectively transmitted.
• Latency:
  • Assess delays which are launched by energy-saving approaches.

9. Advanced Features

  • Forecast traffic models and enhance the energy use with the support of ML models.
• Energy Harvesting:
  • Design scenarios in which nodes are produce energy from its environment.
• Hybrid Networks:
  • Integrate the wired and wireless hybrid networks for discovering energy trade-offs.

10. Visualization and Analysis

• Envision node communication, we want to utilize NetAnim.
• Examine the simulation outcomes leveraging the external tools like Python or MATLAB on energy consumption and performance for in-depth graphs.

11. Extensions
