IMPLEMENTATION OF WIMAX IN NS2

The ns-2 WiMAX PMP module is originally designed and developed by Netowrks & Distributed Systems Laboratory (NDSL) members, Computer Science and Information Engineering, Chang Gung University, Taoyuan, Taiwan, under advisory of Professor Jenhui Chen. All versions of WiMAX modules (current IEEE 802.16d and upcoming IEEE 802.16e and IEEE 802.16j) are freely download for any academic or industrial use. We welcome colleagues to report any bug founded in our provided version and give us some suggestions. All recommendations are welcome. You may directly contact Professor Jenhui Chen or our ns-2 WiMAX module support team members

The Neswork Simulator 2 (ns-2) is an open source tool for various network simulations. The ns-2 provides substantial supports for simulation of the TCP, routing, and multicast protocols covered wired and wireless networks. ns has been a kind of real networks simulator since 1989 and and has been evolved substantially over the past few years. In 1995, the ns development was supported by VINT project at LBL, Xerox PARC, UCB, and USC/ISI. Currently ns development is support through DARPA with SAMAN and through NSF with CONSER, both in collaboration with other researchers including ACIRI .

The Network Simulator 2 (ns-2) is a popular and powerful simulation tool for the simulation of packet-switched networks, which provides substantial support for simulation of TCP, routing, and MAC protocols over wired and wireless networks, such as wireless LANs, mobile ad hoc networks (MANETs), and satellite communications, etc, and is widely used in both academia and industry. Although many protocol modules have been implemented in the ns-2, the IEEE 802.16 broadband wireless access networks (BWANs) or WiMAX module has not been contributed yet. Thus, in this paper, we present our detailed design and implementation of the WiMAX module based on the IEEE 802.16 standard with the point-to-multipoint (PMP) mode for the ns-2. The implemented module comprises fundamental functions of the service-specific convergence sublayer (CS), the MAC common part sublayer (CPS), and the PHY layer. A simple call admission control (CAC) mechanism and the scheduler are also included in this module.

  1. hey I have implemented wimax in ns2.
    its very simple !
    now m trying to improve performance of wimax using diffrent protocols.
    can u help?
    i wanna kno can tcl scripts be implemented on real routers.
    waht bout practical implementation of all these things !

    8. hello Abhishek..!! can u send that ns2 code....I have some ideas to implement other protocols to increase the performance..
      mail id: vimups18@gmail.com...

  2. ya abhishek u can do it .let i want to clarify more on this..since i used some of the protocols to improve the performance ..since i have no idea on practical.

  5. hello
    I want to work on wimax. i am totally new to wimax. I wanted to "implement preauthentication in wimax against dos attacks using visual cryptography". I wanted to know if it is possible to do that implementation part in ns2 or should i go for any other simulator.

  16. Hi,
    I have a project n Security in WiMAX network and Now i'm looking for some Scripts to simulate a WiMAX Network on NS-2.35 and also to see the security side, so PLZ if any one has already worked on this plllz help mee , i neeed it
    and thank you

  17. HI Nana

    Sure will help on wimax so please tell me what security focus on

    detection,prevention and intrusion so that will provide the script based upon that please mail me the base paper to clickprasan@gmail.com so that will help on it

  18. function Net = energyharvesting (Net , i , type , value )
    BatteryCapacity = 1.476 ; % Joules (0.1mAh---3600s---4.1V)
    B = 8*8; % lenght of beacon Bits
    L = 16*8; % lenght of data Bits
    R = 500*1024; %Kbps
    Ptx = 0.0538 ; % Watt
    Prx = 0.0425 ; % Watt
    switch type
    case 'harvest'
    HarvestEnergy = (Net.Node(i).HR/1000)*value ;
    Net.Node(i).AE = min(1,Net.Node(i).AE+HarvestEnergy/BatteryCapacity) ;
    case ' beacon '
    BeaconCost = (B/R)*Ptx + (L/R)*Prx ;%Energy consume to transmit beacon and wait for data
    Net.Node(i).AE = Net.Node(i).AE- BeaconCost/BatteryCapacity ;
    case 'data'
    IdleListeningCost = value*Prx ;% Energy consumption waiting for beacon
    TransmissionCost = (L/R)*Ptx ;% Energy consumption in transmittingdata
    Net.Node(i) .AE = Net.Node(i).AE - (IdleListeningCost + TransmissionCost ) /BatteryCapacity ;
    end
    if Net.Node(i).AE<0
    Net.DeadNode = i ;
    end
    end



    i want code in ns2 forenergy harvesting as energy model for relay networks(lwx)
