 Summary

This documents an ongoing effort (started in 2018) led by UW to develop new ns-3 models for the emerging 802.11ax (High Efficiency WLAN) standard, that builds on existing/prior ns-3 802.11 WLAN implementations (SpectrumWifiClass) and Rel. 13 LTE-LAA. The overall goal is to add new ns-3 features that enable network performance evaluation of next-gen WLAN deployments to explore network efficiency  in dense network scenarios, hence the effort focusses on

  • New Spatial Reuse Aspects: BSS Color, dual NAV and adaptive CCA/Transmit power control mechanisms for enabling multiple simultaneous transmissions in overlapping BSS
  • Dynamic Bandwidth Channel Access & OFDMA: finer granularity in channelization, adapted to user needs provide more knobs for exploring interference management
  • Multi-User MIMO (11ac Downlink Wave 2)  &  Random Access OFDMA Uplink (11ax)
  • Spectrum Coexistence: networks with mixed .11n/ac and .11ax clients as well with non-WiFi clients, specifically LTE-LAA Rel. 13 compliant.

The current version of the 11ax code (intended for ultimate merge into ns-3 11ax branch) can be found @  https://github.com/lanante/ns-3-dev-11ax.
The final version of the project report can be found here: 11ax-final-report. 11ax ns-3 code will be released at a future date along with an update to the report.
