OMNeT++ Simulator [Performance Analysis]

Introduction about OMNeT++ Simulator         

  OMNET++ is a network simulator that functioned for simulating real-time wireless network communication. For example, vehicular communications are visualized in this tool easier. It is a time to increase technical knowledge based on network simulation and simulators. 

           Here, the HITL framework is followed by the OMNeT++. HITL is abbreviated in Hardware-In-The-The-Loop that is mainly designed for dynamic routing and always simulates then real-world process to the sensors. The traditional HITL is only used for the real nodes to find the route to adding nodes and statics routes in OMNeT++.

“We assure you this article boosts up your knowledge about OMNeT++ simulator, its structure, Simu5G, VANET, Veins, Eclipse MOSAIC, and so on.”

Structure of OMNeT++

           OMNeT++ framework gives the perfect structure for many simulators and this framework is specially designed for multipurpose network simulation.

• If we construct a well-defined simulator, then it will also help in multiple ways to reuse any other simulators for example LEGO blocks.
• OMNeT++ frameworks have reusable modules for each simulator so we choose OMNeT++ simulator architecture.
• When this model is compared with the LEGO block structure, OMNeT++ gives a good illustration model.

This is representing the basic structure of the OMNeT++ simulator which is used in the multipurpose network simulation framework. Then we will see about the network Simulator of OMNeT++. It is a platform to perform simulation operations for discrete events in a distributed system.

OMNeT++  Simulator

           The main usage of this tool is used to analyze the performance of networks via simulation and it can be used with wireless communication extensions. This simulator also has the framework for the external model.

• Nowadays, this simulator has been divided into two main parts that have the better suitable model and are more focused on the wireless networks. There are,
• INET Framework
• Mobility Framework
• INET model is implemented by integrating Eclipse MOSAIC and this also provides support to simulate the Vehicle to X (Everything) i.e. V2X Communications.

These are the basics about network simulators in the OMNeT++ simulator. This kind of simulator is a stepping stone for the future simulator line Simu5G. It is the evaluation OMNeT++. Then we will discuss the latest topic Simulator for 5G New Radio Network that is abbreviated as Simu5G.

Use of SimuLTE 

• It is also built for the purpose of an easy-to-use framework. It also holds the modularity concept in the OMNeT++ simulator because it is easy to implement and extend.
• Here also INET framework is implemented to support the optimization tools like CPLEX.
• SimuLTE is moreover like a Simu5G and it can be used to simulate the coexist of both 5G and 4G and it follows,
• E-UTRA/NR Dual Connectivity Deployment (ENDC).
• StandAlone (SA)
• For monitoring the vehicular mobility used to Veins simulator and it’s have integrated with OMNeT++ libraries and SimuLTE. 

Introduction about Simu5G

• Extension of SimuLTE 4G network is considered as a Simu5G this is also have integrated with new 5G radio access.
• It is implemented by using the new protocol and new kind of algorithm derived from researches and it is fully based on the OMNeT++ framework and the structure is written based on the Object-Oriented Programming C++ language. 
• It has interfaces with simple and easy plugins which are customized from the previous version of this simulator.

Use of Simu5G

This Simu5G is a new idea of researches for implementing an easy-to-use framework for the simulation process.

• It provides some optimization tools that as CPLEX which is said to be an optimization solver.
• It is carried out from the concept from OMNeT++ modularity because that is easy to extend the codes and it is also useful to integrate the INET framework with other modules.

• Operating System: Mac OS X, Windows, and Linux
• Platform: INET-Framework v4.2.2 and OMNeT++ v5.6.2

Features of Simu5G: 

The main features of Simu5G are g-NodeB and User terminal.

• The g-NodeB: 
  • The gNB consists of pico, micro, and macro sizable nodes.
  • Round Robin

Until we will see about one of the evaluation technology from OMNeT++ Simulator. It is trending technology in recent times. Then we will go to the other topic that is VANET. It is abbreviated from Vehicular ad-hoc Network this is used for simulate with low cast results and without the risk of the user. Then we will see VANET in a detailed manner.

VANET 

• VANET space has some novel technology models such as 5G, SDN, and Edge Computing.
• To improve the evolution of VANET, the simulator gives a suitable tool that tools are very important to the performance of VANET architecture.
• For the purpose of result credibility, it supports some mechanism that will help the system with secure and safe.

Finding of VANET

• Considering VANET simulation provides a trustworthy micro-mobility and macro mobility of the description the best example of this word is SUMO with has some mobility sensors.
• Most of the tools in VANET simulation are not maintained and are outdated.
• Here we consider the other new simulator that is veins now a day it helps to give support for modern technology with secure and safe. 
• The example of veins is some simulators have the pre-built in functions that is,
• Privacy solutions
• 5G modeling
• Signal attenuation
• Signal interference.

So, VANET is one of the advanced simulators which is widely used in this modern technology. Then we will go through another simulator name veins. Veins are open source software that is mainly used for vehicular network simulations on the basis of SUMO and OMNeT++.

Let us see more clearly about Eclipse MOSAIC,

Eclipse MOSAIC

• VSimRTI is a multi-domain simulation, multi-scale and open-source software framework it provides a new simulation that is automated mobility and connected mobility.
• Here we see some examples of Eclipse MOSAIC. That is,
• Communication simulation in SNS
• SUMO
• OMNeT++
• PHABMACS traffic solution
• NS3
• Applications of Eclipse MOSAIC

Veins Simulator

• In the veins simulator, there is possible to exchange a message between SUMO and OMNeT++ because the use of Veins simulator for example having the mobility traces enables the tool that is TraCl as a part of simulation runs and connection of Transmission Control Protocol.
• In this process each vehicle has the OMNeT++ node then simulates those nodes based on movements of the vehicle, movements of nodes, and traffic.

This is a small introduction about veins then we will move on to the next topic which is Eclipse MOSAIC. It is a framework for the VSimRTI that is V2X Simulation Runtime Infrastructure. Then we will go to discuss some research domains in OMNeT++ Simulator and its advantages and wireless sensor network, wireless body area network, etc.

Wireless Sensor Network

WSN is the developing technology for recent times of researches and is denoted as a collection of nodes. The Simulation of wireless sensor networks represents monitoring environmental or physical conditions with the use of autonomous devices which have a connection with multiple sensors. Here, the node is denoted as different types of actuator, sensors, processing units, power source, memories, and RF transceivers.

Advantages of WSN

Due to the WSN, we have some factors. There are,

• Performing an adaptive new device is possible at any time.
• It is mainly accessed by the centralized monitor.
• It has a flexible physical partition.

Wireless Body Area Network

           WBAN is the medical application system. Here it follows the RF-based communication system. The sensor is inserted into the patient body are some wearable sensors like smartwatches. These sensors collect the data from the patients to the doctor and central monitoring system. Here it has some parameters like temperature, blood pressure, and heart rate, etc. Then we will discuss some recent trends in OMNeT++.
