Once you learn to work also with Omnet++, you can accomplish your 4G Network Simulator projects easily under the guidance of our experts. Now, let’s have a glance also over the simulation steps and procedure followed in Omnet++ for 4G Network Simulation.

4-G NETWORK SIMULATOR FOR OMNET++

4GSIM [4G Simulator]:
  • Open Source 4G Simulation package also for Omnest/Omnet++ Simulation system, developed over Omnet++ INET framework
SimuLTE:
  • Written in C++, also used for performance evaluation of LTE-A and LTE Networks
  • Provides support also for developing new modules and fully customizable with simple pluggable interface
Parameters used for performance evaluation:
  • -To perform evaluation in Omnet++ IDE, two files are also used i.e. .vec or .sca files.
  • -Result analysis is based on the following simulation parameters:
    • Queuelength
    • Packet length
    • Queueing time
    • Throughput
    • Packets transmitted
    • Jitter
    • Link utilization
    • End to End delay

4G SIMULATION IN OMENT++

To Interface 4GSim with Omnet++:
  • Extract the downloaded 4GSim tarball [INET directory]
  • Change the current directory into 4GSim directory
  • Type “Make Makefiles” to generate makefiles and also then type “make” to build simulation executable
  • To build the realeased version, use “make MODE=release”
  • It execute the simulation “./run”
To create a 4G Network Simulation:
  • Requires two files[NED files and .ini files]
  • To Configure the Omnetpp.ini files,

              *.channelControl.carrierFrequency = 2.4GHz

              *.channelControl.pMax = 2.0mW

              *.channelControl.sat = -110dBm

              *.channelControl.alpha = 2

              *.channelControl.numChannels = 12

              *.lteRadio.transmitterPower = 2.0mW

  • Parameters related to feedback computation and channel model are located in Separate XML file:

              **.ue1.configFile = “UE1Config.xml”

              **.enb.configFile = “ENBConfig.xml”

              **.mme.configFile = “MMEConfig.xml”

              **.hss.configFile = “HSSConfig.xml”

              **.pgw.configFile = “PGWConfig.xml”

              **.sgw.configFile = “SGWConfig.xml

  • We have created INI files also for our simulation, next we need to create NED Files[Test]. Network Model Contains two eNodeBs[ENB], each serving two UEs. Here, the UE will communicate with the server.

parameters:

@display(“p=10,10;b=712,152;bgb=540,367”);

types:

channel ethernetline extends ThruputMeteringChannel

{

datarate = 10Mbps;

thruputDisplayFormat = “u”;

}

//submodules:

@display(“p=110,218”);

}

ue2: UE {

@display(“p=30,200”);

}

@display(“p=110,36”);

}

mme: MME {

@display(“p=278,207”);

}

ue1: UE {

@display(“p=106,108”);

}

hss: HSS {

@display(“p=363,129”);

}

pgw: PGW {

@display(“p=448,312”);

}

sgw: SGW {

@display(“p=220,322”);

}

//connections:

enb.ethg++ <–> ethernetline <–> mme.ethg++;

hss.ethg++ <–> ethernetline <–> mme.ethg++;

sgw.ethg++ <–> ethernetline <–> pgw.ethg++;

mme.ethg++ <–> ethernetline <–> sgw.ethg++;

sgw.ethg++ <–> ethernetline <–> pgw.ethg++;

enb.ethg++ <–> ethernetline <–> sgw.ethg++;

}

  • Now, run the simulation and also analyze the overall result

           When the program runs, it first reads all the NED files [contain model topology], then it reads the Configuration file[omnetpp.ini]. INI files contains the settings to controls the overall simulation execution, values also for parameters etc. In the configuration file, the simulation programs run one after another. Output of the Simulation is written in two files [Output vector file/output scalar files and also user’s own output file]. This way a complete simulation is accomplished in Omnet++ using 4GSim.  To learn more about 4G Network simulation in Omnet++, approach us through our online tutoring service. We also will guide you with the help of our expert’s team of researchers.
