The pith

Kom8ndor extends the Komondor simulator with 802.11bn features for Wi-Fi 8 research.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper introduces Kom8ndor as an open-source extension of the Komondor Wi-Fi simulator to model the upcoming IEEE 802.11bn amendment. It adds support for multi-access point coordination mechanisms including Co-TDMA, Co-SR, and Co-BF, along with non-primary channel access and dynamic subband operation. A machine learning wrapper is also included to enable AI-based protocol experiments. The goal is to let researchers explore ultra-high reliability performance targets and prototype new Wi-Fi technologies before hardware is widely available. The simulator remains modular to support ongoing and future amendments.

Core claim

Kom8ndor is a discrete-event network simulator that extends the validated Komondor platform with 802.11bn features such as Multi-Access Point Coordination (Co-TDMA, Co-SR, Co-BF), Non-Primary Channel Access (NPCA), and Dynamic Subband Operation (DSO), plus a machine learning wrapper, to support research on Wi-Fi 8 and beyond.

What carries the argument

The Kom8ndor simulator, which adds modular implementations of 802.11bn mechanisms to the base Komondor platform.

If this is right

  • Researchers gain an open platform to test coordinated multi-AP protocols before Wi-Fi 8 devices ship.
  • Early evaluation of ultra-high reliability targets becomes feasible through the added coordination and channel access features.
  • AI-driven protocol design can be prototyped using the included machine learning wrapper.
  • The modular structure supports incremental addition of later Wi-Fi amendments.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • Community contributions could expand the feature set to cover post-802.11bn ideas more quickly than closed simulators.
  • Cross-validation against ns-3 implementations of the same 802.11bn features would strengthen confidence in the new code.
  • The simulator could serve as a testbed for studying interactions between 802.11bn mechanisms and emerging spectrum-sharing rules.

Load-bearing premise

The newly added 802.11bn features correctly match the amendment specifications and integrate without errors into the base Komondor platform.

What would settle it

Running a standard multi-AP coordination scenario in Kom8ndor and comparing the resulting throughput or latency statistics against measurements from real 802.11bn testbeds or another validated simulator.

The upcoming IEEE 802.11bn amendment marks a paradigm shift in Wi-Fi, which will pose ambitious performance targets under the paradigm of Ultra-High Reliability (UHR). To understand the implications of such a new technology and to support early research and protocol design for Wi-Fi~8, we present \texttt{Kom8ndor}. This discrete-event network simulator extends the open-source Komondor platform (a simulator validated against ns-3 and other analytical tools) with 802.11bn features. Among the newly added functionalities, we highlight Multi-Access Point Coordination (MAPC) -- including Coordinated Time-Division Multiple Access (Co-TDMA), Coordinated Spatial Reuse (Co-SR), and Coordinated Beamforming (Co-BF) -- , Non-Primary Channel Access (NPCA), and Dynamic Subband Operation (DSO). Beyond Wi-Fi~8 implementations, \texttt{Kom8ndor} introduces novel functionalities (e.g., a machine learning wrapper for building AI-based protocols) and a modular design to boost the prototyping and research of future Wi-Fi technologies. \texttt{Kom8ndor} is open-source (GNU GPLv3) and available at https://github.com/wn-upf/Komondor.

Referee Report

1 major / 1 minor

Summary. The paper presents Kom8ndor, a discrete-event simulator extending the validated open-source Komondor platform with IEEE 802.11bn (Wi-Fi 8) features for Ultra-High Reliability operation. The new functionalities include Multi-Access Point Coordination mechanisms (Co-TDMA, Co-SR, Co-BF), Non-Primary Channel Access (NPCA), Dynamic Subband Operation (DSO), plus a machine learning wrapper for AI-based protocols. The code is released under GNU GPLv3 at a public GitHub repository.

Significance. If the new 802.11bn implementations are shown to be correct, the work supplies a reusable, open-source platform that lowers the barrier for early protocol research on MAPC and related UHR mechanisms. The reuse of a previously cross-validated base simulator and the explicit public release constitute concrete strengths for reproducibility.

major comments (1)
  1. [Abstract; Implementation of 802.11bn features] Abstract and the sections describing the new 802.11bn components: the manuscript asserts that Co-TDMA, Co-SR, Co-BF, NPCA and DSO have been added and integrate with the base platform, yet supplies no validation results, packet-level error checks, or quantitative comparison against the 802.11bn draft or against ns-3 for any of these features. This verification step is load-bearing for the central claim that the extensions are functional and faithful to the amendment.
minor comments (1)
  1. [Novel functionalities] The modular design and ML wrapper are mentioned only at a high level; a short usage example or API sketch would clarify how researchers are expected to attach new AI policies.

  1. Referee: [Abstract; Implementation of 802.11bn features] Abstract and the sections describing the new 802.11bn components: the manuscript asserts that Co-TDMA, Co-SR, Co-BF, NPCA and DSO have been added and integrate with the base platform, yet supplies no validation results, packet-level error checks, or quantitative comparison against the 802.11bn draft or against ns-3 for any of these features. This verification step is load-bearing for the central claim that the extensions are functional and faithful to the amendment.

    Authors: We agree that explicit validation strengthens the central claim. The base Komondor simulator was previously cross-validated against ns-3 and analytical models; the new modules were implemented directly from the 802.11bn draft text and inherit the same event-driven engine and channel models. Because the amendment remains in draft form, a definitive quantitative match against a finalized standard is not yet feasible. We will add, in the revised manuscript, (i) a description of the internal consistency checks performed during implementation (e.g., frame-format and timing verification against the draft), (ii) packet-level trace excerpts for each new mechanism, and (iii) a basic performance comparison against the legacy Komondor behavior under equivalent scenarios to demonstrate functional integration. These additions will be placed in a new subsection of the implementation section. revision: yes

Circularity Check

0 steps flagged

No significant circularity; simulator extension is additive and externally benchmarked

full rationale

The paper presents Kom8ndor as an extension of the authors' prior Komondor simulator, adding 802.11bn features (Co-TDMA, Co-SR, Co-BF, NPCA, DSO) plus an ML wrapper. No equations, fitted parameters, predictions, or derivations appear in the provided text. The base platform is described as already validated against ns-3 and analytical tools (external), and the new work is a factual account of implemented functionality rather than a claim that reduces to self-referential inputs or self-citation chains. This matches the default case of a self-contained tool paper with no load-bearing circular steps.
