How to Begin Implementing a M2M Communication in ns3

To stimulate an execution of Machine-to-Machine (M2M) communication project using ns-3 it includes the replicate a communication among the devices deprived of human intervention, frequently as part of IoT (Internet of Things) systems. Below is a detailed guide for setting up and implementing an M2M communication project in ns-3.

Steps to Begin Implementing a M2M Communication projects using ns3

Step 1: Understand M2M Communication

M2M Characteristics:
- Autonomous communication among their devices for sample sensors, actuators, controllers.
- It contains the features for minimum payloads, high device density, and low energy usage.
M2M Use Cases:
- The M2M use cases provide the Smart homes, industrial automation, healthcare monitoring, and environmental sensing.
Protocols for M2M:
- The protocols are M2M in MQTT, CoAP, AMQP.
- At the network layer: LTE, 5G, WiFi, ZigBee.

Step 2: Install ns-3 and Required Modules

Download ns-3:
- Get the latest version from ns-3 official website.
Enable Modules:
- Permit the required modules for M2M project, like as LTE, WiFi, ZigBee such as if applicable, and mobility:

./waf configure –enable-modules=lte,wifi,mobility,internet

./waf build

Verify Installation:
- Process for sample scripts for assure the modules are functioning:

./waf –run lte-simple

./waf –run wifi-simple-infra

Step 3: Define the Project Scope

Scenarios:
- Communication among the cluster for devices and a central server.
- Devices are communicating with the gateway for sample WiFi or LTE.
Metrics:
- The projects give the performance based on the metrices latency, packet delivery ratio, energy efficiency, network throughput.

Step 4: Set Up the Simulation Environment

Create Nodes:
- Express the nodes for devices, gateways, and servers:

NodeContainer m2mDevices, gateways, servers;

m2mDevices.Create(50); // 50 IoT devices

gateways.Create(2); // Two gateways

servers.Create(1); // Central server

Install Internet Stack:
- Install the Internet protocol stack on all nodes:

InternetStackHelper internet;

internet.Install(m2mDevices);

internet.Install(gateways);

internet.Install(servers);

Set Up Mobility:
- Setting the mobility for devices and gateways:

MobilityHelper mobility;

mobility.SetMobilityModel(“ns3::RandomWalk2dMobilityModel”,

“Bounds”, RectangleValue(Rectangle(-100, 100, -100, 100)));

mobility.Install(m2mDevices);

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

mobility.Install(gateways);

mobility.Install(servers);

Step 5: Configure Communication Protocols

WiFi for Local Communication:
- Configure the WiFi for devices communicating by a gateway:

YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default();

YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default();

wifiPhy.SetChannel(wifiChannel.Create());

WifiHelper wifi;

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

WifiMacHelper wifiMac;

Ssid ssid = Ssid(“m2m-network”);

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

NetDeviceContainer deviceWifiDevices = wifi.Install(wifiPhy, wifiMac, m2mDevices);

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

NetDeviceContainer gatewayWifiDevices = wifi.Install(wifiPhy, wifiMac, gateways);

LTE for Wide-Area Communication:
- It configure the LTE for communication among gateways and a central server:

Ptr<LteHelper> lteHelper = CreateObject<LteHelper>();

Ptr<PointToPointEpcHelper> epcHelper = CreateObject<PointToPointEpcHelper>();

lteHelper->SetEpcHelper(epcHelper);

NetDeviceContainer gatewayLteDevices = lteHelper->InstallUeDevice(gateways);

NetDeviceContainer lteEnbDevices = lteHelper->InstallEnbDevice(servers);

lteHelper->Attach(gatewayLteDevices, lteEnbDevices.Get(0));

Traffic Routing:
- Setting the IP addressing and routing for the network:

Ipv4AddressHelper ipv4;

ipv4.SetBase(“10.0.0.0”, “255.255.255.0”);

ipv4.Assign(deviceWifiDevices);

ipv4.Assign(gatewayWifiDevices);

Ipv4InterfaceContainer gatewayLteIf = epcHelper->AssignUeIpv4Address(gatewayLteDevices);

Step 6: Add Applications

M2M Data Generator:
- Build an application for devices the forwarding a periodic data:

UdpEchoServerHelper echoServer(9);

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

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(20.0));

UdpEchoClientHelper echoClient(Ipv4Address(“10.0.0.1”), 9);

echoClient.SetAttribute(“MaxPackets”, UintegerValue(100));

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

echoClient.SetAttribute(“PacketSize”, UintegerValue(512));

ApplicationContainer clientApps = echoClient.Install(m2mDevices);

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(20.0));

Centralized Processing:
- Use the server application for executes the data.

Step 7: Configure Performance Monitoring

Flow Monitor:
- Gather the network performance metrics for flow tracking:

FlowMonitorHelper flowMonitor;

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

Enable Tracing:
- Log packet are transmissions and responses for the debugging:

AsciiTraceHelper ascii;

wifiPhy.EnableAsciiAll(ascii.CreateFileStream(“m2m-trace.tr”));

Step 8: Run the Simulation

Schedule and process for the replication:

Simulator::Stop(Seconds(20.0));

Simulator::Run();

Simulator::Destroy();
