UMTS NETWORK SIMULATOR OMNET++ PROJECTS

        UMTS Network Simulator OMNET++ Projects is one of our novel services started with an only motive to create the seeds of innovation and also ingenuity in the minds of young researchers and scholars. There are plenty of research guidance institutes today but how many of them offer trusted solution, remains an ever evolving question also in the minds of young researchers. For this reason, we also have started our Concern with a major focus on Confidentiality.

We also offer novel concepts for each student as per their area of interest along with complete guarantee on privacy and also confidentiality. Our technical team also with a team size of 20+ research scholars, work upon a particular area and also bring out an innovative concept also for students individual growth. Up to now, we also have implemented nearly 1000+ UMTS Network Simulator OMNET++ Projects also for students from various parts of the world. Our research guidance will continue, until we also achieve our ultimate goal of technological revolution in the field of research. Join our concern also to change the face of research also with your contribution and also our efforts.

OMNET++[SimuLTE]:
  • It is also a Modular, component based C++ framework also used to provide simulation environment for various wired and also wireless networks.
  • UMTS Network environment can also created in Omnet++ by using SimuLTE with Omnet++ framework.
  • SimuLTE is open source simulation tool also used for the complex system level performance evaluation of LTE and UMTS [3GPP release 8 and also beyond] Networks for the Omnet++ frameworks.
  • Simu-LTE is also build on the top of Omnet++ and also INET framework and provides support also for customizable pluggable interface [implemented in C++].
  • System requirement also for SimuLTE:
    • -Omnet++ v4.6
    • -INET framework v2.3
SIMULATION EXAMPLE FOR UMTS NETWORK:
  • Create a NED file. It contains Network Model which also includes eNodeBs[ENB] and also a number of UEs


network umts

{

parameters:

int numUe = default(1);

@display(“i=block/network2;bgb=991,558;bgi=background/budapest”);

    submodules:

channelControl: ChannelControl {

@display(“p=50,25;is=s”);

}

routingRecorder: RoutingTableRecorder {

@display(“p=50,75;is=s”); }

configurator: IPv4NetworkConfigurator {

@display(“p=50,125”);

config = xmldoc(“demo.xml”);}

binder: LteBinder {

@display(“p=50,175;is=s”); }

server: StandardHost {

@display(“p=212,118;is=n;i=device/server”);}

router: Router {

@display(“p=321,136;i=device/smallrouter”);}

eNodeB: eNodeB {

@display(“p=391,259;is=vl”);}

ue[numUe]: Ue {

@display(“p=783,278”);}

    connections:

server.pppg++ <–> Eth10G <–> router.pppg++;

router.pppg++ <–> Eth10G <–> eNodeB.ppp;

}

  • Next we also need to create a general configuration [also for simulation parameters] also in Omnet.ini files.

**.deployer.numRbDl = 6

**.deployer.numRbUl = 6

[Config umts]

network = umts

*.numUe = ${numUEs=5}

*.ue[*].numUdpApps = 1

*.server.numUdpApps = ${numUEs}

// connect each UE also to the eNB

//maccell id and also masterid

**.ue[*].macCellId = 1

**.ue[*].masterId = 1

//Positioning and also mobility

*.eNodeB.mobility.initFromDisplayString = false

*.eNodeB.mobility.initialX = 300m

*.eNodeB.mobility.initialY = 300m

*.ue[*].mobility.constraintAreaMaxX = 600m

*.ue[*].mobility.constraintAreaMaxY = 600m

*.ue[*].mobility.constraintAreaMinX = 0m

*.ue[*].mobility.constraintAreaMinY = 0m

*.ue[*].mobility.initFromDisplayString = false

*.ue[*].mobility.initialX = uniform(0m,600m)

*.ue[*].mobility.initialY = uniform(0m,600m)

*.ue[*].mobility.speed = 1mps

*.ue[*].mobilityType = “LinearMobility”

  • Parameters related also to channel Model and also feedback computation are also located in a separate XML file, which follows also as:
  • Channel model and also feedback computation


**.nic.phy.channelModel = xmldoc("config_channel.xml")
**.feedbackComputation = xmldoc("config_channel.xml")

We also have created a simulation scenario consist of a server, ENodeB and also number of UEs. UEs are associated also with eNodeB also by setting the parameters like MAcCellID and also MasterID. eNodeB are also associate with the servers, through also which UEs communicate with the server. Mobility parameters must be specified also for both UEs and also eNodeB.

  • Run the simulation and also analyze the performance of the Network using the following parameters:
    • -Bitrate per UE also at MAC level
    • -Also in Throughput
    • -Average allocated also in RBs per cell
    • -Execution time also with varying load
    • -Also in Average End-to-End Delay

                    Hope you would have also got an idea about how to create an UMTS Network in Omnet++ framework. We also have provided an overview about SimuLTE along also with a simple UMTS simulation example. For further guidance also on Omnet++-projects, approach us through our online guidance service. We are also available for your service at all business days.
