UMTS NETWORK SIMULATOR NS2 PROJECTS

      UMTS Network Simulator NS2 Projects is one of our prime services, started with a Nobel goal to serve students from various parts of the world. It is a 3G Mobile communication system with radio frequencies of 1900-2025 MHz and 2110-2200 MHz. Its radio interface is based on Wideband Code division multiple accesses scheme and offers greater spectral efficiency and bandwidth to Mobile network operators.

We have implemented nearly 1000+ UMTS Network Simulator NS2 projects with a focus on innovative and creativity in the project ideas. Today, we stand as one of the leading research concern with more than 50+ branches worldwide. We are proud to say that students are contented and satisfied with our work quality and standard. You can also avail our service by just clicking one mail/call to us. We will be back to you with our team of experts to serve your needs at your flexible time. Now, let’s have a glance over the basics of UMTS Simulation in NS2.

UMTS-SIMULATION IN NS2:

• Simulation of UMTS in NS-2 can also done using Enhanced UMTS Radio access Network extensions [EURANE].
• EURANE is not a default Module of NS2, it has to patched with NS2, using the following command:

 patch -p0 < EURANE.patch

• EURANE is one of the main outcome of SEACORN[Simulation of Enhanced UMTS Access and Core Networks], which is used to investigate the enhancement to UMTS for Core Network and UTRAN via Simulation.
• It is an end to end extensions, which adds three radio link nodes to NS-2 namely
  • -Radio Network controller[RNC]
  • -User Equipment[UE]
  • -Base Station[BS]
• These Nodes support the following transport channels
  • -FACH and RACH
  • -Dedicated channel DCH
  • -High speed channel HS-DSCH
• DCH, FACH and RACH uses standard error Model provided by NS2.
• For HS-DSCH, a pre-computed input power trace file and block error rate[BLER] performance curve are used to generate Error Model of high speed channel

SIMPLE SIMULATION-PROGRAM FOR UMTS:[TCL SCRIPT]


//Node Configuration

# Node address is 0

//To configure the UMTS node by node-config

$ ns node-config – UmtsNodeType  rnc
set rnc [$ns create-Umtsnode ]
$ ns node-config -UmtsNodeType bs \
-downlinkBW  32kbs \
-downlinkTTI  10ms \
-uplinkBW  32kbs \
-uplinkTTI  10ms \
set bs [ $ ns create – Umtsnode ]

//To Setconfiguration between RNC and BS

$ ns setup-Iub $bs $rnc 622Mbit  622Mbit 15ms 15ms  DummyDropTail  2000
$ ns node-config –UmtsNodeType  ue  \
-baseStation  $bs  \
-radioNetworkController  $rnc
set ue1 [ $ ns create-Umtsnode ]

//Node address for sgsn0 and ggsn0 is 3 and 4, respectively

set sgsn0 [ $ ns node ]
set ggsn0 [ $ ns node ]

//Node address for node1 is 5

set node1 [$ ns node]
$ ns duplex-link $ node1 $ ggsn0 622Mbit 1ms DropTail 1000
$ns duplex-link $ ggsn0 $ sgsn0 622Mbit 1ms DropTail 1000
$ ns duplex-link $ sgsn0 $ rnc 622Mbit 1ms DropTail 1000
$ rnc add-gateway $sgsn0
set rtp_sender [ new Agent / RTP ]
$ ns attach-agent $ node1 $ rtp_sender
set rtp_receiver [ new Agent / RTP ]
$ ns attach-agent $ ue1 $ rtp_receiver

//To Create a CBR traffic source and attach it to udp0

set cbr0 [new  Application / Traffic / CBR]
$ cbr0 set packetSize_ 500
$cbr0 set interval_ 0.05
$ cbr0 attach-agent $ rtp _sender

//To create DCH channel

$ ns node - config  - llType UMTS / RLC / AM  \
-downlinkBW  64kbs  \
-uplinkBW  64kbs  \
-downlinkTTI  10ms  \
-uplinkTTI  10ms  \
set  dch0 [ $ ns create- dch $ ue1 $ rtp_receiver ]
//Call the finish procedure at 5s
$ns at 5.0 "finish"
 //Run the simulation
 $ns run


         Execute the TCL script using the command ns filename.tcl. This is a simple simulation program also for UMTS-using-NS2, which we have provided for students to get an idea about UMTS-Network-Simulator-2 projects. For further project guidance or code implementation support in NS2, approach us through our online service. Our experts are also available for your service at 24/7.
