How to Begin Implementing a MANET Projects Using NS3

To stimulate an estimation of Mobile Ad Hoc Network (MANET) project using NS3 have involves the replicate a wireless network in which the mobile nodes communicate deprived of predefined structure. Below is a detailed guide to help you get started:

Steps to Begin Implementing a MANET Projects Using NS3

Step 1: Understand MANET Concepts

1. Key Features of MANET:
   • Dynamic topology: The mobile nodes are can have the join/leave the network dynamically.
   • Multi-hop communication: Nodes transmit the packets for every other.
   • Decentralized architecture: No stable for base station or permits the point.
2. Routing Protocols in MANET:
   • Proactive (Table-driven): DSDV, OLSR.
   • Reactive (On-demand): AODV, DSR.
   • Hybrid: ZRP.
3. Performance Metrics:
   • It based on the performance metrices such as throughput, packet delivery ratio, average delay, and routing overhead.

Step 2: Set Up NS3 Environment

1. Install NS3:
   • Download and install NS3 from the official website.
   • Validate the installation through processing the sample scripts.
2. Enable Required Modules:
   • Assure the modules such as Wifi, Mobility, AODV, OLSR, and DSR are enabled.
3. Visualization Tools:
   • Install the tool like NetAnim or PyViz for envision the network activity.

Step 3: Design the MANET

1. Topology:
   • Choose the number of nodes their placement and mobility.
2. Mobility Models:
   • Use predefined designs such as:
     • Random Waypoint Mobility.
     • Gauss-Markov Mobility.
     • Constant Velocity Mobility.
3. Routing Protocols:
   • Select the routing protocols according to the project goals:
     • AODV for on-demand routing.
     • OLSR for proactive routing.
4. Traffic Models:
   • Choose the kind of congestion such as TCP, UDP, and CBR.
   • Describe the sources and destinations.

Step 4: Implement the MANET in NS3

1. Create Nodes:
   • It can use the node like a NodeContainer for build and handle the MANET nodes.
2. Configure Wireless Communication:
   • Use the setting a WifiHelper, YansWifiPhyHelper, and YansWifiChannelHelper for configure the WiFi communication.
3. Set Up Mobility:
   • Use MobilityHelper for execute the mobility pattern in the nodes.
4. Install Internet Stack:
   • Make use the stack like InternetStackHelper for enable the IP-based communication.
   • Install the MANET-specific routing protocols for sample AODV.
5. Generate Traffic:
   • Use applications like OnOffApplication or UdpEchoApplication for generate the network congestion.

Step 5: Simulate and Trace

1. Set Simulation Time:
   • Describe the duration of replication using the Simulator::Stop().
2. Enable Tracing:
   • Ensure the tracing tools like AsciiTrace, PcapTrace, FlowMonitor for log the network action.
3. Run the Simulation:
   • Use the process like Simulator::Run() for implement and monitor the replication.

Step 6: Analyze Results

1. Collect Data:
   • Excerpt the performance of metrics such as throughput, delay, and packet loss from trace files.
2. Visualize:
   • Use the tool is NetAnim for envision the node action and communication.
   • Examine the data with tools like MATLAB, Python (Matplotlib), or Excel.
3. Optimize Parameters:
   • Research by mobility, node density, and congestion design for examine the performance metrices.

Step 7: Document and Present

1. Prepare Documentation:
   • The log for the simulation setup, outcomes, and observations.
2. Present Results:
   • Use the outcomes for graphs, charts, and tables for express the findings..

Example NS3 Script for MANET

Simulating a MANET Using AODV

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/mobility-module.h”

#include “ns3/internet-module.h”

#include “ns3/aodv-module.h”

#include “ns3/applications-module.h”

#include “ns3/wifi-module.h”

using namespace ns3;

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

// Step 1: Create nodes

NodeContainer nodes;

nodes.Create(10); // 10 MANET nodes

// Step 2: Configure mobility

MobilityHelper mobility;

mobility.SetMobilityModel(“ns3::RandomWaypointMobilityModel”,

“Speed”, StringValue(“ns3::UniformRandomVariable[Min=1.0|Max=3.0]”),

“Pause”, StringValue(“ns3::ConstantRandomVariable[Constant=2.0]”),

“PositionAllocator”, StringValue(“ns3::GridPositionAllocator”));

mobility.Install(nodes);

// Step 3: Configure WiFi

YansWifiPhyHelper phy = YansWifiPhyHelper::Default();

YansWifiChannelHelper channel = YansWifiChannelHelper::Default();

phy.SetChannel(channel.Create());

WifiHelper wifi;

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

WifiMacHelper mac;

mac.SetType(“ns3::AdhocWifiMac”);

NetDeviceContainer devices = wifi.Install(phy, mac, nodes);

// Step 4: Install Internet stack with AODV

AodvHelper aodv;

InternetStackHelper stack;

stack.SetRoutingHelper(aodv); // Set AODV as the routing protocol

stack.Install(nodes);

Ipv4AddressHelper address;

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

Ipv4InterfaceContainer interfaces = address.Assign(devices);

// Step 5: Create traffic

UdpEchoServerHelper echoServer(9);

ApplicationContainer serverApps = echoServer.Install(nodes.Get(0));

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

UdpEchoClientHelper echoClient(interfaces.GetAddress(0), 9);

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

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

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

ApplicationContainer clientApps = echoClient.Install(nodes.Get(1));

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

// Step 6: Enable tracing

phy.EnablePcap(“manet-aodv”, devices);

// Step 7: Run simulation

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;
