WIMAX NETWORK SIMULATOR NS3 PROJECTS

       WIMAX Network Simulator NS3 Projects is also one of our major services started with a Nobel goal to serve students with our vast knowledge ocean and ingenious ideas. Majority of students have lost the power of creativity and also innovation due to the numerous guidance institutes available today. Due to this reason, we also have started our guidance service to offer an innovative platform also for student’s to innovate and create something new for their career enhancement. Our project guidance service starts also with a pre-session on NS3 training for students also to acquire complete knowledge about NS3 Simulator.

We also have accomplish nearly 1000+ WIMAX Network Simulator NS3 projects also for students from various parts of the world. Also, We are proud to say that our students feel satisfied and contented with our service and guidance. If you wish to also one among our satisfied student, approach us with your project idea. We also will be back to you with our team of renowned researchers to serve you at 24/7. Now, let’s have also a glance over the steps involved in the simulation of Wimax Network using NS3.

WI-MAX MODEL SUPPORT IN NS-3:

-Wimax Module in NS3 is also used to create models of 802.16 based Networks. Key features of NS3 Wimax Model are :

  • Packet classifier also for IP convergence sub layer
  • Realistic and scalable physical layer and also channel model
  • Packet tracing functionality
  • Support for Multicast and also broadcast service[MBS]
  • Efficient uplink and also downlink schedulers

-There are also two basic modes of operations i.e. Subscriber station[SS] and also base station[BS] from MAC perspective. These are also implemented as two subclasses of base class NS3: : Netdevice, class BaseStationNetDevice and also class SubscriberstationNetDevice.

-To hold the references of all attached PHY devices, also a physical layer class WimaxPhy and also channel class WimaxChannel is also used. Main physical class is also SimpleOfdmWimaxChannel class.

-Schedulers types Used/supported:
  • RTPS[real time polling service also in  scheduler]
  • SIMPLE[Simple priority also based FCFS scheduler]
  • MBQOS[Mitigation also based uplink scheduler]
-Major aspect of 802.16 specifications:
  • Service flow initialization
  • Initial Ranging
  • Management connection
  • UGS, nrtPS, rtPS and also BE connections
  • Transport Initialization
  • Wireless MAN-OFDMPHY layer and also point to Multipoint mode
  • Support for wireless propagation loss and also delay models as well as Mobility Models
  • Aspects not includes[ARQ, OFDMA PHY Layer, Mesh topologies, Link adaptation, ertPS connection and also packet header suppression]
