How to Implement Multimedia sensor network in OMNeT++

To implement a Multimedia Sensor Network (MSN) in OMNeT++ encompasses some important stages. Following the explained notes to get in progress:

Step-by-Step Implementations:

1. Set Up OMNeT++

1. Install OMNeT++:
   • From the orginal OMNeT++ to download and install it.
   • For the operating system we move the installation directives.
2. Install INET Framework:
   • For the network protocols and instruments are provided by INET framework to download and install it
   • Open the INET framework addicted to the OMNeT++ workspace.
   • Exposed OMNeT++ IDE, ingress the INET project, and form it.

2. Design the Multimedia Sensor Network Architecture

1. Define the Network Structure:
   • To recognize the modules of the MSN, like multimedia sensors, sink nodes, and possibly intermediate relay nodes.
   • To conclude the statement rules and data flow concerning these apparatuses.
2. Create the Network Nodes:
   • To make fresh ones for the detailed components like sink nodes, multimedia sensor nodes or encompass present INET nodes.
   • Explain the factors and possessions of the nodes like energy consumption, video/audio data generation.

3. Develop the Simulation Modules

1. Multimedia Sensor Node Module:
   • To encompass a new one for the multimedia sensor nodes or to make a new modules.
   • Transmission, density and audio or video data generation to execute these functionality.
2. Sink Node Module:
   • To gather and development data from the sensor node to explain a module to present sink nodes.
   • Make a certain to the module could switch the big data rates and accomplish data collection and exploration.

4. Implement Communication Protocols

1. Define Communication Interfaces:
   • To delineate the interfaces for communication amongst the sink nodes and        multimedia sensor.
   • By using INET’s message-passing system we increase the data mechanisms.
2. Simulate Network Traffic:
   • For simulate the multimedia data like audio clips, and video streams from the sensor nodes to make a traffic generators.
   • For the error handling, compression, and the data routing we improve the algorithms.

5. Implement Mobility and Energy Models

1. Define Mobility Models (if applicable):
   • To build a fresh ones to simulate the movement of sensor nodes such as mobile cameras or in INET by using the existing mobility models.
   • Make a certain the mobility model interacts through the communication modules to return alterations in the network topology.
2. Implement Energy Models:
   • To create the energy usage of multimedia sensor nodes to implement the energy depletion copies.
   • To enhance the network’s lifetime to apply the energy-aware proprieties.

6. Configure the Simulation

1. Network Configuration File (NED):
   • Compose NED files to state the network topology and formation.
   • In the network we require the types and relations of nodes.
2. Simulation Configuration File (INI):

• In the certain simulation parameters like data generation rates, logging options, node properties, and simulation time to build the INI files.
• In the MSN implementation to constitute altered set-ups to calculate the concert.

7. Run and Analyze the Simulation

1. Run the Simulation:
   • By using the OMNeT++ IDE to compile and run the simulation.
   • To display the simulation for any faults or surprising performance.
2. Collect and Analyze Results:
   • To gather the simulation information using the OMNeT++’s tools built-in investigation.
   • Consider the metrics like data latency, energy consumption, packet loss, network lifetime, throughput, and packet loss to estimate the enactment of the MSN execution.

Example Code Snippets

Given some example code snippets for give an idea of the files.
