What is ns-3?
As a matter of fact, NS-3 is majorly implemented in C++, which holds a wide range of libraries and modules to support discrete-event models. It is the packet-level open source software with the abilities of interactive testbeds, parallel clusters, and real code execution. Further, it also comprises the followings,
- One-stop simulator to study the behavior and performance of the real-time and non-real-time networks
- A different set of contributed modules from community support to build new models.
Next, we can see how the 5G project using the NS3 tool is executed in a single machine / PC. This will explicitly show the functionalities of NS3 in the different layers. Here, we have mentioned the physical, MAC, Transport, Network, and Application layer in the order of NS3 5G simulation.
How does NS3 Works?
- Physical Layer
- High-fidelity models (WiFi and LTE)
- Mobility models
- IEEE 802.15.4 standard
- Energy extension
- Radio propagation
- MAC Layer
- Enable packets scheduling through a network interface in testbeds
- Activates the transmission of the logical service from the source device to the application hosts.
- Routing packets from the source to the destination node.
- Run the real-time software or application programming interfaces (APIs) for end-users usage
So far, we have debated on the fundamental of NS3 and the workflow of the NS3 system. Now, we can see the importance of the 5G system in cellular communication. These are the key factor that stimulates everyone to move on toward the Ns3 5G Simulation research.
Why simulation for 5G wireless networks?
- Test orchestration is costly on a different scale
- Replication of experiments for better performance
- To analyze the RF interference and coordination
- Low-level access of Testbeds is not repeatedly offered to alter devices operation
Further, our resource team is given the role of NS3 simulator in 5G communication developments. Generally, NS3 simulation is performed based on the IEEE standards such as IEEE 802.11-14 and IEEE 802.11ax. Also, it is assessed through the 3GPP standard protocol for examining the licensed and unlicensed spectrum.
By the by, the simulation duration differs in discrete depends on the event. Below, we have mentioned the other features supported in the NS3 module.
- Once the event completes its execution, it automatically ends the simulation.
- Simulation::Run() is the method used to run the single-thread program.
- Schedulers are used to command the event to begin the simulation.
- Only at a certain time period, the C++ method schedules the events to perform.
- Enable developers to use C++ (central language) and python NS3 (supportive language) code for writing the program to perform simulation
- Support in-built mmWave library to construct, test, and simulate 5G models. In some cases, it includes EPC for the purpose of policies, mobility, identity verification, etc.
- The open-source network simulation tool used to model and virtualize both IP and Non-IP Networking systems
What is meant by Module in NS3?
NS3 is made up of huge-scale pre-defined libraries, classes, and modules to execute all sorts of simple and complex algorithms, protocol, and system design. Further, every module has the ability to extend through full backward compatibility. For example, ns–3 LTE module.
5G NS3 Simulation Steps
- At first, we have to express the development scenario for simulation.
- Then, code the program for reconstructing the network design of the required simulation scenario. And, this can be performed through the mmWave supportive module by means of the “ns3::mmwave helper” interface.
- Next, denote the metrics used for configuring the network components involved in the simulation using ns3:: Configstore interface.
- At last, configure the required outcome to implement the simulation process.
Next, our developers have specified the important performance metrics used to evaluate the behavior of the 5G network in NS3 simulation. Since performance assessment is the common phase to be executed in all kinds of NS3 5G Simulation.
- Metrics for analyzing the simulation performance
- Average SINR Versus Number of Users
- SINR Versus User with Line of Sight Connection
- Bit Rate Versus Users with NLoS and Los Connections
- SINR Versus User with Non-Line of Sight Connection
