How to Implement IoT in OMNeT++

To implement an Internet of Things (IoT) network in OMNeT++ has embarrasses numerous steps, with setting up the required frameworks, scheming the network architecture, developing simulation modules, and organizing and running the simulation. The given below is to get the procedure of implement of IoT in OMNeT++.

Step-by-Step Implementation:

  1. Set Up OMNeT++
  1. Install OMNeT++:
    • from the official OMNeT++ to download and install OMNeT++.
    • For the operating system, we follow the installation instructions.
  2. Install INET Framework:
    • For the network protocols and devices to install and download the INET framework.
    • Decompress the INET framework addicted to the OMNeT++ workstation.
    • Exposed OMNeT++ IDE, import the INET project, and form it.
  1. Design the IoT Network Architecture
  1. Define the Network Structure:
    • Ascertain the workings to the IoT network, like IoT devices, gateways, and cloud servers.
    • To conclude the interaction protocols and data flow among these components.
  2. Create the Network Nodes:
    • Encompass existing INET nodes or build new ones for explicit components like IoT devices, gateways.
    • Explain the parameters and properties of these nodes such as knowing capabilities, communication borders.
  1. Develop the Simulation Modules
  1. IoT Device Module:
  • To form a new module an existing one for IoT devices.
  • Appliance functionalities like data knowing, local processing, and statement with gateways.
  1. Gateway Module:
    • To make a module to denote gateways that total data from IoT devices and connect with cloud servers.
    • Device functionalities like data aggregation, protocol translation, and forwarding.
  2. Cloud Server Module:
    • Create or range a module for cloud servers that process and store data received from gateways.
  1. Implement Communication Protocols
  1. Define Communication Interfaces:
    • Express the interfaces for connect along IoT devices, gateways, and cloud servers.
    • Gadget data exchange mechanisms with INET’s message-passing system.
  2. Simulate Network Traffic:
    • Create traffic generators to simulate sensor data and control messages.
    • Implement algorithms for data routing, aggregation, and handling.
  1. Implement IoT-Specific Features
  1. Data Sensing and Generation:
    • Improve algorithms for data sensing and group on IoT devices.
    • Instrument data formats and protocols right for IoT communication.
  2. Energy Models:
    • Device energy consumption models to simulate the energy custom of IoT devices.
    • To advance energy-aware protocols to optimize the network’s lifetime.
  1. Configure the Simulation
  1. Network Configuration File (NED):
    • Write NED files to define the network topology and configuration.
    • Specify the types and connections of nodes in the network.
  2. Simulation Configuration File (INI):
    • Create INI files to specify simulation parameters such as simulation time, node properties, data generation rates, and logging options.
    • Configure different scenarios to evaluate the performance of your IoT network implementation.
  1. Run and Analyze the Simulation
  1. Run the Simulation:
    • To compile and run the simulation by using the OMNeT++ IDE.
    • Monitor the recreation for any errors or sudden conduct.
  2. Collect and Analyze Results:
    • By custom OMNeT++’s built-in exploration tools to gather simulation data.
    • Consider metrics such as latency, throughput, packet loss, and energy consumption to appraise the performance of the IoT network enactment.

Example Code Snippets:

Given below is an example for snippets to give  some thoughts.

NED File (IoTNetwork.ned)

package iotnetwork

import inet.node.inet.Router;

import inet.node.inet.StandardHost;

import inet.node.ethernet.EtherSwitch;

network IoTNetwork {

submodules:

iotDevice[10]: StandardHost {

@display(“p=100,100;i=device/sensor”);

}

gateway: Router {

@display(“p=300,300;i=device/router”);

}

cloudServer: StandardHost {

@display(“p=500,500;i=device/server”);

}

connections:

for i=0..9 {

iotDevice[i].ethg++ <–> gateway.ethg++;

}

gateway.ethg++ <–> cloudServer.ethg++;

}

INI File (omnetpp.ini)

[General]

network = iotnetwork.IoTNetwork

sim-time-limit = 1000s

*.iotDevice*.wlan[0].typename = “IdealWirelessNic”

*.iotDevice*.numApps = 1

*.iotDevice*.app[0].typename = “UdpBasicApp”

*.iotDevice*.app[0].destAddresses = “gateway”

*.iotDevice*.app[0].destPort = 5000

*.iotDevice*.app[0].messageLength = 100B

*.iotDevice*.app[0].sendInterval = exponential(1s)

*.gateway.wlan[0].typename = “IdealWirelessNic”

*.gateway*.numApps = 1

*.gateway*.app[0].typename = “UdpSink”

*.gateway*.app[0].localPort = 5000

*.cloudServer.wlan[0].typename = “IdealWirelessNic”

*.cloudServer*.numApps = 1

*.cloudServer*.app[0].typename = “UdpSink”

*.cloudServer*.app[0].localPort = 6000
