How to Implement Mobile Computing in OMNeT++

Implementing Mobile Computing in OMNeT++ involves several steps, including setting up the necessary frameworks, designing the network architecture, developing simulation modules, and configuring and running the simulation. Get in touch with us for best simulation and implementation guidance.

Below is a comprehensive guide to help you get started:

Step-by-Step Implementation:

  1. Set Up OMNeT++
  1. Install OMNeT++:
    • Make sure to install the OMNeT++ .
    • You can install it according to your operating system.
  2. Install INET Framework:
    • Install the INET framework, which provides models for network protocols and devices.
    • In the OMNeT++ workspace, disengage the INET framework.
    • Open OMNeT++ IDE, import the INET project, and build it.
  1. Design the Mobile Computing Network Architecture
  1. Define the Network Structure:
    • In mobile computing network, classify the components of like mobile devices, access points (APs), and possibly cloud servers.
    • Determine the communication protocols and data flow among these components.
  2. Create the Network Nodes:
    • Prolong existing INET nodes or create new ones for specific components (for instance, mobile devices, APs).
    • Define the parameters and characteristics of these nodes (for instance, mobility patterns, communication interfaces).
  1. Develop the Simulation Modules
  1. Mobile Device Module:
    • Create a new module or extend an existing one for mobile devices.
    • Implement functionalities like data generation, local processing, and communication with APs.
  2. Access Point Module:
    • Define a module to represent APs that manage connections with mobile devices and relay data to the core network or cloud servers.
    • Execute the functionalities like connection management and data forwarding.
  3. Cloud Server Module (Optional):
    • Create or extend a module for cloud servers that process and store data received from APs or directly from mobile devices.
  1. Implement Communication Protocols
  1. Define Communication Interfaces:
    • Among the mobile devices, APs, and cloud servers, determine the interfaces for communication.
    • Use message-passing system of INET to execute data exchange mechanisms.
  2. Simulate Network Traffic:
    • Among the mobile devices and Aps, we have to simulate the data transmission and reception by creating traffic generators.
    • Implement algorithms for data routing, handover management, and error handling.
  1. Implement Mobile-Specific Features
  1. Mobility Models:
    • Simulate the movement of mobile devices by using existing mobility models in INET or create new ones.
    • Example contains Random Walk, Random Waypoint, and Gauss-Markov mobility models.
  2. Handover Mechanisms:
    • Implement handover algorithms to manage the transition of mobile devices between various APs as they move.
  3. Energy Models (Optional):
    • Simulate the mobile device’s battery usage by implementing energy consumption models.
    • Enhance the lifetime of the network by building an energy-aware protocols.
  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 like simulation time, node properties, traffic generation rates, and logging options.
    • Configure various situations to examine the performance of mobile computing network implementation.
  1. Run and Analyze the Simulation
  1. Run the Simulation:
    • Compile and run the simulation with the help of OMNeT++ IDE.
    • Monitor the simulation for any errors or unexpected behavior.
  2. Collect and Analyze Results:
    • Accumulate the simulation data by the in-built analysis tools of OMNeT++.
    • Analyze metrics includes data rate, latency, packet loss, handover success rate, and energy consumption to evaluate the performance of your mobile computing network implementation.

Example Code Snippets

Here are some example snippets to give you an idea of what the configuration files might look like:

NED File (MobileComputingNetwork.ned)

package mobilecomputing;

import inet.node.inet.Router;

import inet.node.inet.StandardHost;

network MobileComputingNetwork {

submodules:

mobileDevice[10]: StandardHost {

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

mobility.typename = “inet.mobility.single.RandomWaypointMobility”;

}

accessPoint[3]: Router {

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

}

cloudServer: StandardHost {

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

}

connections:

for i=0..2 {

accessPoint[i].pppg++ <–> cloudServer.pppg++;

}

for j=0..9 {

mobileDevice[j].wlan[0] <–> accessPoint[j % 3].wlan[0];

}

}

INI File (omnetpp.ini)
