3Installation and Installation Problems Step 1

There are two ways to install ns simulatorall in one packet or from peaces (for Windows,Windows XP and LINUX)

from this link we have downloaded all-in-one version of ns simulator ns-2.26

http://www.isi.edu/nsnam/dist/file name ns-allinone-2.26.tar.+

all in one packet works only under Linux system !

4Installation and Installation Problems Step 2

After you have downloaded ns simulator you have to download these files from this web address

http://www.ti-wmc.nl/eurane/download this file ns-eurane-106b.diff.gzbecause this is patch file for ns-2.26 version !test_tcp.tcl test script for validation of installing

MatlabPreprocess.tar.gz Matlab scripts to generate input trace files

SNRBLERMatrix.gz this file gives error model for HS-DSCH

Eurane_user_guide_1_3.pdf

5Installation and Installation Problems Step 3 First problem : installation under Red Hat did not work, we had to

install it under KNOPPIX 3.0 version

before doing any thing check the compiler version !

Installation procedure for ns : create directory called ns2cd ns2gunzip ns-allinone-2.26.tar.gztar xvf ns-allinone-2.26.tarcd ns-allinone _2.26./ installif this procedure goes ok, then you run this command ./validate Do not forget to change environmental variables after installing

procedure!

6Installation and Installation Problems Step 4

If you have successfully built ns

Put the path to your ns executable into your PATH environment

Put the path to your otcl into your LD_LIBRARY_PATH environment

Put the path to your tcl library into your TCL_LIBRARY environment

7Installation and Installation Problems Step 5

Now we can proceed to the patching of E.U.R.A.N.E module

You have to patch diff file to the clean distribution of ns simulator !go to ns-2.26 directory and run the command

guzip ns-eurane-106b.diff.gzpatch p1 < ns-eurane-106b.diff.after this you compile and run this command ns test_script.tcl

8Installation and Installation Problems Step 6

I have explained in short the procedure for installing of ns simulator

ns-2.26 version;This is an older version ,new one ns-2.27 has just revealed ,butbecause this is an open source software the older versions are far better cleaned from bugs

So in my opinion I recommend ns-2.26

Network simulator version 2 and EURANE

Ns is a discrete event simulator

Open source simulator with many bugs

Network simulator is not a polished and finished product, but the result of an on-going effort of research and developers

Description of E.U.R.A.N.E

EURANE is short of Enhanced UMTS Radio Access Network extension for ns-2

It applies three new nodes BS, UE ,and RNC

Allow to support these transport channels - FACH- RACH - DCH- HS-DSCH

13

Description of E.U.R.A.N.E

Single cell implementation no handovers, mobility models, load control

No power control available for the DCH, FACH and RACH

For HS-DSCH they assume this curve for error model

log3 7.010

Error model for RACH, FACH and DCH Fixed error probability set

Simulations

Always use even number of users for HSDSCH,FACH,RACH and DCH

After you run simulations you have to now what scripts representout.tr is the name of trace fileFor more information go to ns-manual on the this web adresshttp://www.isi.edu/nsnam/ns/to find what format of trace filesr stands for received packet+ stands for beginning of queuing - stands for end of queuingd stands for dropt packet

17

Simulations For FACH and RACH you can not simulate two applications at the

same time for two users

There are very little tools who can help you to do fast evaluationbased on the trace files that you have generated

One of them is nans2

To install this tool you need to have installed Java

With this tool you can calculateTHROUGHPUTSequence number vs. TimeRTT vs TimeTHROUGHPUT(One way) vs. time
