WIMAX NETWORK SIMULATOR NS2 PROJECTS is also one of our prime services started with the collaborative efforts of renowned researchers and network experts from all over the world. We also have started our service in a Nobel goal to serve students with our knowledge ocean, which we have gained through our vast experience.

We have accomplished nearly 1000+ WIMAX NETWORK SIMULATOR NS2 PROJECTS with an only focus on innovation and creativity in the project idea. NS2 is also one of the powerful simulators used by majority of research scholars and also developers today, which can also used to simulate Wimax Network also using Wimax patch file.

NS2 Tutoring Service

We offer complete project guidance along with NS-2 tutoring service for our students as we believe that one must learn to code before undertaking a project. We can assure you that, even you come to us as a beginner in NS2, we can make you a Master of NS-2 with the help of our immense guidance service. Approach us, if you want also to be an expert of NS-2 to accomplish your project by your self. Now, let’s have also a glance over few fundamentals of Wimax simulation in NS-2.

  • -In NS2 is a popular discrete event simulator, which also supports the simulation of TCP, MAC and also Routing protocols over wired and wireless networks.
  • -It is also targeted at network research and also is implemented in C++ and TCL[Tool command language]
  • -NS2 does not have any inbuilt support for Wimax Network. We also have to patch a Wimax Module with NS2 to simulate Wimax Networks.
  • -Wimax Module provide support for TDD Mode, PMP topology, service flow type, bandwidth request/grant mechanism and also used to configure QoS requirements of the applications.
-Available features in NS2 for Wimax Simulation:
  • Support for Wireless MAN-OFDMA physical layer also with configurable modulation
  • In this Support also for TDD[Time division duplexing]
  • Default scheduler also with round robin uplink allocation
  • IEEE 802.16e extensions[for scanning and also handover]
  • Fragmentation and also reassembly of frames
  • OFDMA physical layer
  • QoS scheduling and also service flow
  • Management messages to execute network entry
  • Mobile stations according also to required bandwidth
  • Fast fading models[ITU PED A, VEHIC A, also PED B]
  • Per-subcarrier interference modeling also with EESM
  • ARQ and CDMA based contention resolution
  • Concatenation [Multiple MAC PDUs packet also into single PHY burst]


It can be simulated in NS2 using patch method. We have to use Wimax awg patch file based on nsallinone package version. Following steps are carried out in order to patch a Wimax module/patch file with NS2:

  • Download the software ns-allinone- 2.xx package and also download the latest NS2 Wimax module/patch file source code. You can also create your own patch file
  • Unzip the patch file and put the file from “MAC” directory into ns-allinone-2.xx\ns-2.xx\mac
  • Put the files that are common and TCL into ns-allinone-2.xx\ns-2.xx\common and ns-allinone-2.xx\ns-2.xx\tcl respectively
  • Modify the Makefile.in as follow:
    • -After MAC/MAC-802_3.o add – mac/mac-802_16-base.o mac/mac-802_16-ss.o mac/mac-802.16-bs.o\ and mac\mac-802.16-FSM.o mac/mac-802.16-timers.o\
  • Now, go to ns-allinone-2.xx/ns-2.xx directory and execute “./configure” , “make clean” and “make”
  • Patch command to be used [patch –p0<wimax_awg.patch]
Steps to write a Wimax Simulation program:
  • Wimax works under IEEE 802.16 standard and has a mobility extension IEEE 802.16e
  • To configure the Node[MAC and Physical layers are specified in TCL]
$BSWithWiMax  node - config

-macType Mac / 802_16 / BS

-phyType Phy / WirelessPhy / OFDMA

$SSWithWiMax node – config

-macType  Mac / 802_16/SS

-phyType Phy / WirelessPhy / OFDMA

  • To configure packet Classifier:

//To Create classifier

set classifier  [new SDUClassifier/ Dest]

// To Set classifier priority

$ classifer  set – priority 1

// To Retrieve  MAC layer and delete all registered classifiers

[$ nodeWithWiMax set mac_( 0 )] reset – classifiers

//Retrieve  MAC layer and set classifier

[$ nodeWithWiMax set mac_( 0 )] add-classifier $ classifier

             Here, we have used default classifier[DestClassifier] to the MAC. To change the classifier, reset the list and add a new classifier

  • To Configure the scheduler:

   MAC layer uses different types of scheduler. Here, we have created scheduler for one base station[BS] and one subscriber station[SSs]

//Create scheduler

set scheduler [ new WimaxScheduler / BS]

//Add scheduler

[$ nodeWithWiMax  set  mac_( 0 )] set-scheduler $ scheduler// automatically created when MAC 802.16BS created

// For MAC 802.16 MSS

// Create scheduler

set  scheduler [new WimaxScheduler / SS]

// Add scheduler

[$ nodeWithWiMax  set  mac_( 0 ) ] set-scheduler  $ scheduler

  • To configure the Channel

// To retrieve the MAC layer and set classifier

[ $ nodeWithWiMax set mac_( 0 ) ] set-channel 1 # valid 0-4

  • To select OFDMA Propagation Model

set  opt( prop ) Propagation / OFDMA

  • To select a Fading Model

set  prop_inst [$ ns set propInstance_]

$ prop_inst  ITU_PDP PED_A  //other choices are PED_B, VEHIC_A

  • To display the values during simulation

        Mac / 802_16  set  print_ stats _  true

  • To create a trace file

              r - t 0.032311472 -Hs 3 -Hd -1 -Ni 3 -Nx 45.06 -Ny 50.00 -Nz 0.00 -Ne -1.000000 -Nl   RTR -Nw — - Ma 0 - Md 0 -Ms ffff0008 -Mt 0 -Is 4194304.255 -Id -1.255 - It message -Il  32 - If 0 - Ii 1 - Iv 32

       This is the overall steps involved in the simulation of Wimax network in NS2. Based on the simulation output, performance analysis is done. Throughput, packet loss rates, end to end delay are few metrics used for performance analysis.
