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.
