How to Start Cooperative Networking Projects Using NS3

To start a Cooperative Networking project in NS3 that has contains to configure a network where nodes collaborate to enhance overall network performance, improve reliability, and then prolong coverage. Cooperative networking methods are frequently utilized within wireless networks to support the nodes relay data which is specifically once direct interaction is unreliable or insufficient. Mentioned below is a simple guide to improving a Cooperative Networking project in NS3:

Steps to Start Cooperative Networking Projects in NS3

  1. Define Project Objectives and Scope
  • Find out the kind of cooperative networking we need to replicate like relay-based cooperative communication, cooperative routing, data forwarding, or resource sharing.
  • Select certain objectives like enhancing the network throughput, to improve coverage, minimizing power consumption, or maximizing reliability via cooperation.
  1. Install NS3 and Set Up the Environment
  • Go to NS3 official website to download and install NS3 on the system.
  • Check the installation by executing sample simulations, verifying NS3 is operating properly.
  1. Understand NS3 Modules for Cooperative Networking
  • WiFi or LTE Modules: If we are executing the cooperative communication across wireless networks to utilize the wifi or lte modules.
  • Energy Models: It is helpful if the cooperation includes the energy-efficient data relaying or resource sharing.
  • Mobility Models: It is crucial for replicating the mobile nodes, which actively modify the cooperative interaction structure.
  • Routing Protocols: Configure multi-hop interaction among the nodes to use routing protocols such as AODV, DSDV, or custom protocols.
  1. Design the Cooperative Network Topology
  • Configure a network topology including several nodes in which some nodes might perform like source nodes, relay nodes, and destination nodes.
  • We make situations in which cooperation is necessary like nodes beyond the direct range to require other nodes to relay messages.
  1. Implement Cooperative Communication
  • Relay Nodes: Select certain nodes like relay nodes, from source to destination to send data.
  • Multi-Hop Communication: Set routes to data packets hop via intermediate nodes using dynamic or static routing protocols, or describe custom routes.
  • Application Layer Cooperation: Replicate the data generation on the source and set the relay and destination to obtain and send this information cooperatively to utilize applications such as OnOffApplication.
  1. Set Up Cooperative Protocols
  • Direct Relaying: Utilize basic forwarding in which relay nodes obtain the packets and send them to the destination.
  • Decode-and-Forward or Amplify-and-Forward: We execute protocols in which relay nodes either decode and re-encode the data (decode-and-forward) or increase the signal (amplify-and-forward).
  • Opportunistic Routing: Send packets based on availability or quality of nodes by the path to utilize dynamic routing.

Note: Custom cooperative protocols need to prolong the NS3 by means of making custom applications or altering the routing modules.

  1. Configure Metrics for Performance Evaluation
  • Throughput: We estimate the data rate that is attained by cooperative networking compared to direct interaction.
  • End-to-End Delay: Compute the time it takes, moving from source to destination for packets.
  • Packet Delivery Ratio: Estimate the effective rate of packet delivery within cooperative situations.
  • Energy Consumption: If energy efficiency is a crucial focus then examine energy usage for each node.
  1. Run Simulations and Analyze the Results
  • Run several replications including different volume of relay nodes, distances, or traffic loads to compute how cooperation impacts network performance.
  • Gather information to utilize NS3’s tracing and logging capabilities for analysis.
  • Envision and examine the outcomes to equate the cooperative vs. non-cooperative situations.

Example Code Outline for a Cooperative Network in NS3

Following is an example of configuring a simple cooperative network in which one node perform as a relay among the source and the destination:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/wifi-module.h”

#include “ns3/applications-module.h”

#include “ns3/mobility-module.h”

using namespace ns3;

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

// Create nodes: source, relay, and destination

NodeContainer nodes;

nodes.Create(3);

// Configure WiFi settings

WifiHelper wifi;

wifi.SetStandard(WIFI_PHY_STANDARD_80211b);

YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default();

YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default();

wifiPhy.SetChannel(wifiChannel.Create());

WifiMacHelper wifiMac;

wifi.SetRemoteStationManager(“ns3::AarfWifiManager”);

Ssid ssid = Ssid(“cooperative-network”);

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

NetDeviceContainer devices = wifi.Install(wifiPhy, wifiMac, nodes);

// Set up mobility for nodes

MobilityHelper mobility;

mobility.SetPositionAllocator(“ns3::GridPositionAllocator”,

“MinX”, DoubleValue(0.0),

“MinY”, DoubleValue(0.0),

“DeltaX”, DoubleValue(10.0),

“DeltaY”, DoubleValue(10.0),

“GridWidth”, UintegerValue(3),

“LayoutType”, StringValue(“RowFirst”));

mobility.SetMobilityModel(“ns3::ConstantPositionMobilityModel”);

mobility.Install(nodes);

// Install the internet stack

InternetStackHelper stack;

stack.Install(nodes);

Ipv4AddressHelper address;

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

Ipv4InterfaceContainer interfaces = address.Assign(devices);

// Set up an application at the source node

uint16_t port = 9;

OnOffHelper onoff(“ns3::UdpSocketFactory”, InetSocketAddress(interfaces.GetAddress(2), port));

onoff.SetConstantRate(DataRate(“1Mbps”));

ApplicationContainer sourceApp = onoff.Install(nodes.Get(0));  // Source node

sourceApp.Start(Seconds(1.0));

sourceApp.Stop(Seconds(10.0));

// Set up a packet sink at the destination node to receive the traffic

PacketSinkHelper sink(“ns3::UdpSocketFactory”, InetSocketAddress(Ipv4Address::GetAny(), port));

ApplicationContainer sinkApp = sink.Install(nodes.Get(2));  // Destination node

sinkApp.Start(Seconds(1.0));

sinkApp.Stop(Seconds(10.0));

// Add a routing table at the relay node

Ptr<Ipv4> ipv4 = nodes.Get(1)->GetObject<Ipv4>();

Ipv4StaticRoutingHelper ipv4RoutingHelper;

Ptr<Ipv4StaticRouting> staticRouting = ipv4RoutingHelper.GetStaticRouting(ipv4);

staticRouting->AddHostRouteTo(Ipv4Address(“10.1.1.3”), 2, 1);

// Run the simulation

Simulator::Run();

Simulator::Destroy();

return 0;

}

Additional Considerations

  • Enhanced Relay Strategies: Test with diverse relay strategies, according to the signal strength or data rate such as selective relaying.
  • Dynamic Topologies: Experiment with dynamic topologies in which nodes modify the location that needing relays to adapt routes actively.
  • Advanced Routing Protocols: Deliberate to execute more complex cooperative routing protocols such as Cooperative AODV or B.A.T.M.A.N. for large networks.
  • Performance in Adverse Conditions: Replicate the situations along with interference or obstacles to experiment the cooperative networking’s efficiency.
