    • Predictive Maintenance: Design sensors to gather information forecasting equipment failures.
    • Remote Monitoring and Control: Configure networks for observing processes and remotely managing equipment.
    • Smart Grid or Energy Management: In a smart grid context, mimic IIoT for energy consumption management and distribution.
  • Determine Key Performance Metrics: These may contain crucial performance parameters like latency, reliability, energy consumption, scalability, and data throughput.
  1. Install and Set Up NS3
  • Download NS3: Go to official NS3 website to download new version of NS3 on the system.
  • Installation: We adhere to the installation guidelines as per operating system.
  • Verify Installation: Then we execute an example NS3 simulation script verifying that the installation is functioning properly.
  1. Understand NS3 Modules Relevant to IIoT Networks
  • Wireless Communication Modules:
    • 802.15.4 Module: This module is helpful for low-power, short-range interactions in industrial environments, which is generally utilized within IoT devices.
    • WiFi Module: Useful for larger data transmission ranges and higher throughput requirements.
    • LTE Module: If replicating the long-range, high-capacity IIoT interaction then LTE can function like the backbone.
  • Energy Models:
    • Battery Models: Mimic battery-powered sensors that are significant for remote or mobile IIoT devices.
    • Energy Harvesting Models: It is helpful if designing devices, which depend on energy harvesting like solar-powered sensors.
  • Mobility Models (if applicable):
    • Static Position: For stationary devices such as sensors and machinery.
    • Random Walk Mobility: It is helpful for mobile equipment or automated guided vehicles (AGVs) within a factory.
  • Network Stack:
    • IPv4 and IPv6 Support: Select according to the IIoT use case; for IoT, IPv6 is more scalable.
    • Routing Protocols: We can utilize AODV, DSDV, or rely on the complexity of network and needs, make custom routing protocols.
  1. Design the Network Topology
  • Define IIoT Nodes:
    • Sensors: For observing metrics like temperature, humidity, vibration, and so on.
    • Controllers: From sensors executing the data and then transmit commands to actuators.
    • Actuators: Devices, which execute actions from the network depends on the control signals.
    • Gateway Nodes: Associating IIoT devices to the broader network, cloud, or centralized control system.
  • Topology Layout:
    • According to the industrial environment’s physical layout, to organize nodes.
    • For instance, locate sensors around machinery including controllers and gateways located to handle the clusters of devices.
  1. Configure IIoT Communication and Protocols
  • Wireless Network Setup:
    • Configure wireless connectivity to utilize NS3’s 802.15.4 or WiFi modules.
    • Set the MAC and PHY layers based on the IIoT specifications like low-power operation or frequency settings preventing the interference.
  • IoT Protocol Simulation:
    • Although NS3 doesn’t directly support application-layer IoT protocols such as MQTT or CoAP then we can replicate same behavior to utilize UdpEcho or OnOffApplication.
    • If essential, make custom applications simulating the data aggregation, reporting intervals, or alert-triggered interactions.
  1. Implement Data Collection and Processing Applications
  • Sensor Data Collection:
    • Replicate the periodic data generation from sensors using OnOffApplication.
    • Set the data rate and packet size to suit the real-world sensor data patterns.

    • Gateways can be gathered information from sensors and send it to a central server or cloud. Replicate the data aggregation using NS3’s PacketSink.
  • Event-Driven Communication:
    • We execute the event-driven applications in which sensors send alerts according to the threshold conditions such as a high-temperature alert.
  1. Configure Network Management and Security (Optional)
  • Quality of Service (QoS):
    • Configure priorities for various kinds of data traffic making sure that critical information like emergency alerts is distributed along with low latency.
  • Security Simulations:
    • We need to replicate encryption or simple security mechanisms, measuring the influence over network performance.
    • NS3 environment doesn’t offer extensive built-in security aspects thus we want to utilize custom delay values, signifying the encryption processing time.
  1. Define Key Performance Metrics
  • Latency: We estimate the end-to-end delay for critical messages.
  • Throughput: For various kinds of IIoT traffic, we need to monitor data transmission rates.
  • Packet Delivery Ratio: Make sure that reliability that specifically for control and alert messages.
  • Energy Consumption: Observe the energy usage of battery-powered devices.
  • Network Scalability: Examine how performance modifications depends on the number of devices maximizes.
  1. Simulate and Analyze the Results
  • Run Simulations:
    • Test with various network sets up, traffic patterns, and mobility scenarios as applicable.
  • Collect Data:
    • Record events and then accumulation performance information to utilize NS3’s tracing mechanisms such as AsciiTrace, PcapTrace, and so on.
    • Transfer gathered information examining IIoT network behavior in diverse conditions.
  • Analyze Results:
    • Envision performance parameters to utilize external tools such as Matplotlib or Gnuplot.
    • Then, analyse how the network converges latency, reliability, and energy efficiency objectives for the IIoT application.
