How to Implement UWB Communication In NS3

To Implement Ultra-Wideband (UWB) communication in ns-3 by creating a network topology which uses UWB for high-speed, short-range communication. ns-3 does not have built-in support for such communication. so, it is possible to simulate UWB-like behaviour using the existing ns-3 modules by configuring high data rates and appropriate physical layer properties. The following steps will guide on how to simulate UWB communication in ns-3.

Prerequisites

• ns-3 installed on your system.
• Basic understanding of ns-3 and C++ programming.                                                      

Step-by-step to Implement UWB Communication in ns-3

1. Install ns-3: Ensure you have ns-3 installed. You can download it from the official website and follow the installation instructions.

wget https://www.nsnam.org/release/ns-allinone-3.xx.tar.bz2

tar -xjf ns-allinone-3.xx.tar.bz2

cd ns-allinone-3.xx

./build.py –enable-examples –enable-tests

Include Necessary Headers: Include the required headers for network modules, mobility, internet, and point-to-point links.

#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/applications-module.h”

Create Network Topology: Create nodes representing the devices in the UWB network.

NodeContainer nodes;

nodes.Create(2); // Create 2 nodes for UWB communication

Set Up Mobility Model: Configure the mobility model to simulate the placement and movement of the devices.

MobilityHelper mobility;

mobility.SetPositionAllocator(“ns3::GridPositionAllocator”,

                              “MinX”, DoubleValue(0.0),

                              “MinY”, DoubleValue(0.0),

                              “DeltaX”, DoubleValue(10.0),

                              “DeltaY”, DoubleValue(10.0),

                              “GridWidth”, UintegerValue(2),

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

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

mobility.Install(nodes);

Set Up Point-to-Point Links: Configure point-to-point links to simulate UWB communication by setting high data rates and low propagation delays.

PointToPointHelper pointToPoint;

pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“100Gbps”));

pointToPoint.SetChannelAttribute(“Delay”, StringValue(“1us”));

NetDeviceContainer devices;

devices = pointToPoint.Install(nodes);

Install Internet Stack: Install the internet stack on the nodes.

InternetStackHelper stack;

stack.Install(nodes);

Assign IP Addresses: Assign IP addresses to the devices.

Ipv4AddressHelper address;

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

Ipv4InterfaceContainer interfaces = address.Assign(devices);

Create Applications: Create and install applications to simulate data transmission between the nodes.

uint16_t port = 9;

OnOffHelperonoff(“ns3::UdpSocketFactory”, Address(InetSocketAddress(interfaces.GetAddress(1), port)));

onoff.SetConstantRate(DataRate(“10Gbps”));

ApplicationContainer app = onoff.Install(nodes.Get(0));

app.Start(Seconds(1.0));

app.Stop(Seconds(10.0));

PacketSinkHelpersink(“ns3::UdpSocketFactory”, Address(InetSocketAddress(Ipv4Address::GetAny(), port)));

app = sink.Install(nodes.Get(1));

app.Start(Seconds(0.0));

app.Stop(Seconds(10.0));

Run the Simulation: Finally, run the simulation and clean up.

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

Example Complete Script

Here is an example script for setting up a basic UWB communication simulation in ns-3:

#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/applications-module.h”

using namespace ns3;

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

{

    NodeContainer nodes;

    nodes.Create(2); // Create 2 nodes for UWB communication

    MobilityHelper mobility;

    mobility.SetPositionAllocator(“ns3::GridPositionAllocator”,

                                  “MinX”, DoubleValue(0.0),

                                  “MinY”, DoubleValue(0.0),

                                  “DeltaX”, DoubleValue(10.0),

                                  “DeltaY”, DoubleValue(10.0),

                                  “GridWidth”, UintegerValue(2),

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

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

    mobility.Install(nodes);

    PointToPointHelper pointToPoint;

    pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“100Gbps”));

    pointToPoint.SetChannelAttribute(“Delay”, StringValue(“1us”));

    NetDeviceContainer devices;

    devices = pointToPoint.Install(nodes);

    InternetStackHelper stack;

    stack.Install(nodes);

    Ipv4AddressHelper address;

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

    Ipv4InterfaceContainer interfaces = address.Assign(devices);

    uint16_t port = 9;

    OnOffHelperonoff(“ns3::UdpSocketFactory”, Address(InetSocketAddress(interfaces.GetAddress(1), port)));

    onoff.SetConstantRate(DataRate(“10Gbps”));

    ApplicationContainer app = onoff.Install(nodes.Get(0));

    app.Start(Seconds(1.0));

    app.Stop(Seconds(10.0));

    PacketSinkHelpersink(“ns3::UdpSocketFactory”, Address(InetSocketAddress(Ipv4Address::GetAny(), port)));

    app = sink.Install(nodes.Get(1));

    app.Start(Seconds(0.0));

    app.Stop(Seconds(10.0));

    Simulator::Stop(Seconds(10.0));

    Simulator::Run();

    Simulator::Destroy();

    return 0;

}

Running the Script

Compile and run the script using the following commands:

./waf configure –enable-examples

./waf build

./waf –run <script-name>

Finally, the  UWB communication is implemented in ns-3 and simulated get best coding support from us .
