NS3 Wimax Simulation

WiMAX (Worldwide Interoperability for Microwave Access) is a telecommunications protocol describing fixed and fully mobile Internet access services.We assist Engineering students and Research Scholars in implementing Ns3 Wimax simulation Projects based on their requirement.WiMAX technology is a broadband wireless data communications technology based around the IEE 802.16 standard providing high speed data over a wide area.

WIMAX versions:

  • 16d (802.14-2004).
  • 16e (802.16-2005).

WIMAX QoS:

In order to gain QoS in wimax there are five different QoS classes are defined. There are,

  • Non-real time packet services.
  • Unsolicited grand services.
  • Best effort..
  • Real-time packet services.
  • Extended real time packet services.

 Architecture of WIMAX:

wimax-architecture

Features of WIMAX:

  • Accessibility.
  • Long rang.
  • Mobility.
  • Interfacing.

Sample code for WIMAX:

This is the sample code for wimax.
