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.

Remarkable NS3 LTE programming languages

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
  • Windows-7 32 bit

The system type and the Operating System software are more important to implement the simulation process. And our suggested Operating systems are good for effective simulation. In addition to the OS, we introduce you to the versions of LTE tools

Important Versions of LTE tools

  • NS-3.26
  • NS-3.31

The exceeding tools are the best of our recommendation by our engineering team implement for simulation. Besides, we give to the suitable stimulation protocols for LTE as follows

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

X2 Application Protocol

o          This class enables the control plane signaling among dual eNBs and E-UTRAN by the X32 interface. Generally, the x2 interface are purposed for

  • 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

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.

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,

LTE subject wise modules

To execute the LTE simulation, the LTE itself is considered as one of the best subject-wise modules. Here is the major syntax of LTE as follows,

Notable LTE syntax


LteMiErrorModel::GetPcfichPdcchError (const SpectrumValue& sinr)



double MI;

double MIsum = 0.0;

SpectrumValue sinrCopy = sinr;

Values::iterator sinrIt = sinrCopy.ValuesBegin ();

uint16_t rb = 0;D2D Communication

NS_ASSERT (sinrIt!=sinrCopy.ValuesEnd ());

while (sinrIt!=sinrCopy.ValuesEnd ())


double sinrLin = *sinrIt;

if (sinrLin > MI_map_qpsk_axis[MI_MAP_QPSK_SIZE-1])


MI = 1;




// since the values in MI_map_qpsk_axis are uniformly spaced, we have

// index = ((sinrLin – value[0]) / (value[SIZE-1] – value[0])) * (SIZE-1)

// the scaling coefficient is always the same, so we use a static const

// to speed up the calculation

static const double scalingCoeffQpsk =

(MI_MAP_QPSK_SIZE – 1) / (MI_map_qpsk_axis[MI_MAP_QPSK_SIZE-1] – MI_map_qpsk_axis[0]);

double sinrIndexDouble = (sinrLin –  MI_map_qpsk_axis[0]) * scalingCoeffQpsk + 1;

uint32_t sinrIndex = std::max(0.0, std::floor (sinrIndexDouble));

NS_ASSERT_MSG (sinrIndex < MI_MAP_QPSK_SIZE, “MI map out of data”);

MI = MI_map_qpsk[sinrIndex];


MIsum += MI;




MI = MIsum / rb;

// return to the effective SINR value

int j = 0;

double esinr = 0.0;

while ((j<MI_MAP_QPSK_SIZE)&&(MI_map_qpsk[j] < MI))




if (MI > MI_map_qpsk[MI_MAP_QPSK_SIZE-1])


esinr = MI_map_qpsk_axis[MI_MAP_QPSK_SIZE-1];




NS_ASSERT_MSG (j<MI_MAP_QPSK_SIZE, “MI map out of data”);

// take the closest value (when possible)

if (j>0)


if ((MI_map_qpsk[j]-MI)<(MI-MI_map_qpsk[j-1]))


esinr = MI_map_qpsk_axis[j];




esinr = MI_map_qpsk_axis[j-1];





esinr = MI_map_qpsk_axis[0];



double esirnDb = 10*log10 (esinr);

//   NS_LOG_DEBUG (“Effective SINR ” << esirnDb << ” max ” << 10*log10 (MI_map_qpsk [MI_MAP_QPSK_SIZE-1]));

uint16_t i = 0;

double errorRate = 0.0;

while ((i<PDCCH_PCFICH_CURVE_SIZE)&&(PdcchPcfichBlerCurveXaxis[i] < esirnDb))




if (esirnDb > PdcchPcfichBlerCurveXaxis[PDCCH_PCFICH_CURVE_SIZE-1])


errorRate = 0.0;





errorRate = PdcchPcfichBlerCurveYaxis[i];



return (errorRate);
