Ns3 LTE | Network Simulator 3 – Long Term Evolution Projects

NS3 LTE: a Summary: NS3 is a type of network simulation tool that simulates the given network in its unique characteristics called performance metrics. In case of that, the term LTE stands for the Long Term Evolution, which is in name of immortality across generations. Combining this network simulator with the LTE network, unlock the research gateway with various aspects of the researching subdomains.

“Through this article, we are attempting to enable your vision over the LTE network simulation and you can get the techniques, parameters, selecting the simulation tool for LTE network and our knowledge over the NS3 LTE!!”

Advantages of NS3 LTE

The major advantage of LTE lies in the Channel realization, which executes the whole propagation model utilized by the channel to calculate the packet loss in the signal broadcast. The elements of channel realization are intended to create all pairs of UE – eNB

Purpose of LTE modules

When it comes to the modules, NS3 has an in-built LTE module to perform simulation. It doesn’t need to have any foreign module for the simulation purpose.

Significant classes of LTE

LteHarqPhy: it is used to apply the functions of HARQ that are associated with the physical layer like an increase to manage the termination

LteFfrAlgorithm: at the application process of this class, there is a dependency of FR policy to reuse the frequency that requests the scheduler to distribute the RB

The above-mentioned classes are the notable classes of LTE simulation. These are existing samples for our research purpose apart from that we are intended to afford you the integrated tools of  LTE as follows

Importance and purpose of integrated tools

For simulation, the NS3 has LTE as a typically integrated tool, for the high evaluation of the performance of the network.

For the NS3 simulator, the programing language is C++

Appropriate OS for LTE

• 32-bit Operating System (System Type)
• 4 GB (RAM)
• Intel® Pentium(R) CPU G2030 @ 3.00GHz × 2 (Processor)

And the supporting OS are

• Ubuntu-14.04

Notable LTE protocols

S1 Application Protocol (S1AP)

o          It affords the control plane signaling to both the EPC and E-UTRAN. The user interface in this protocol is positioned among the eNB and MME and the user interface is S1-MME. We can get both UE related and non-UE related services separated in S1AP

• UE related mobility procedures
• Dual connectivity procedures
• Global procedures among eNBs

`           The above-mentioned protocols are considered as the important protocols for NS3 LTE simulation. In addition to the protocols

Advanced NS3 LTE subjects

• Vehicular sensor network

The well-known architecture of the VSN enables the communication process among vehicle to vehicle, vehicle to RSU vise-versa, and RSU to RSU. These communications are possible with either Ethernet wired link or a cellular wireless link.

• Satellite communication

The idea of primary structure based on the hybrid LTE satellite or the terrestrial communications enables the data to be shared in the identical frequency band. In this process, the eNodeB of the SAE gateway receives the data from the satellite’s base station and transmits to the UE of both the hybrid satellite and the terrestrial eNodeB and the Internet enables the service.

The above is the real-time subjects of LTE. And these are our sample subjects of the NS3 LTE simulator. Besides the subjects, we offer you the major parameters, metrics, and QoS as follows.

Research Analysis on NS3 LTE

• Handoff Latency: it creates the packet loss and measures in terms of seconds (s). This parameter relies on certain features of
  • Link delay
  • Layer 2 delay
  • Address resolution delay
  • Protocol delay
• Node velocity: it calculates the undertaking of each node and stated in terms of (m/s)
• Power consumption: it calculates the quantity of energy utilized by the node. The energy consumption is measured in terms of milli joule (MJ) or joules.

The mentioned parameters are the metrics used to analyze the performance of the LTE network performance. These are the fundamental parameters of the network. Apart from the given parameters,
