NS3 Wimax Simulation (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:
Features of WIMAX:
- Accessibility.
- Long rang.
- Mobility.
- Interfacing.
Sample code for WIMAX:
This is the sample code for wimax.
