Simulation is a process of analyzing the performance of the network to detect data transmission in simulation environments etc. When implementing LTE simulation process to a network, the networking program would simulate some regulations to avoid random anomalies and it controls the system by regulating the entries of such inputs by governing the user behavior.

“This article focuses on the LTE Simulation networks and our suggestion on the best simulation tools for LTE networking and further, we provide you the appropriate and trending research aspects over the LTE networks!!”

Functions of LTE Networks

  • Simulated user equipment web browsing
  • Mobile web browsing
  • Enabling the calls of 4G user through CSFB to 2G/3G user
  • IMS VoLTE calls
  • Enabling usual voice calls in mobiles

The above functions are the fundamental functions that can be achieved through the LTE simulation, and implementing simulation in LTE network for research purposes in mobile networks will also have those features as research limitations. In addition to those fundamental functions, we provide you the categories of traffic in LTE networks

Trending Top 9 LTE Simulation Project Topics

LTE Traffic Types

  • Multiple PDP contexts
  • Internet connectivity
  • Supplementary IN services
  • FTP, Email, MMS, SMS
  • Video, Voice, Fax

Generally, the traffic in networking occurs while we are attempting to transfer packets from the source to the destination. In this process, the router creates a common link to transmit the packet and the link will be used widely at both the sender and the receiver side. If the transmitting network is not simulated properly, the packets we are sending would face a collision and it results in delayed transmission and the process start to buffer to clear the traffic and queue the packet. The above-mentioned traffic types are the most common traffic types in LTE networks.

Motivation of LTE simulation

Through simulation, you can learn to assess the network performance and the simulation process is important to estimate the complexities in closed formulas and in unavailable numerical techniques. And simulation studies will help you to structure alternative evaluating designs. And the simulation process can be implemented only in research and it will enhance your knowledge in handling the issues in a real system, which is expensive, complex, and almost unavailable.

How to program simulation in a structure?

There are three fundamental elements to be included in a simulator for an effective simulation based on the

  • Given time
  • Given events
  • Given state

Whatever the simulation types and the field of the network we are implementing the simulation process; the computing feature will be based on the above terms/parameters.

  • The event simulation: computes the point of time taken by the network to transmit a packet particularly, when the system changes state in each event that has associated the event time and it analyses the system model in the given time among the events created by external environments.
  • The system state simulation: analyze the variables upheld by the performed simulation program on the basis of the network state. For instance, it can be able to track the number of queuing packets and current retransmission timing values.
  • The simulated time: this is a type of internal simulation process that tracking the simulated time taken for the transmission in a network.

The above elements are the required programs of a simulator. To construct a simulator, the required components are a well-defined set of events to perform simulation for each event action and to update the event list. It is because the simulation program upholds and updates the future event lists. Before knowing and implanting the simulator for the research purpose, it is important to be familiarized with the components presented in the simulator. As we are approaching the simulator from a research point of view, we provide you the research objectives of the LTE network simulation stating below.

Research objectives of LTE simulation

The main aim of the LTE simulation is to assess and test the numerous features and conducting research studies of LTE networks like

  • Analyzing LTE radio tasks (UE interface)
  • Assessing End user functions
  • Computing LTE transport functions (S1/X2 interface)

In order to achieve those objectives, a simulation model must be designed to model both the E-UTRAN and EPC. After the focused modeling with the significant performances and characteristics of the protocols and nodes, the models would have intensive performance until implementation research studies.

As per our suggestion, the fixed LTE networking simulation would be less complicated when compared to the mobile network, as it involves numerous functionalities and utilities. Along with the research objectives and the components of LTE networking, we provide you the basic functions of the LTE simulation
