Kom8ndor: An IEEE 802.11bn-Oriented Simulator for Wi-Fi 8 and Beyond
🤖 AI Summary
This work addresses the lack of simulation tools for ultra-high reliability (UHR) research in Wi-Fi 8 (IEEE 802.11bn) by developing a discrete-event network simulator built upon the open-source Komondor platform. The proposed simulator is the first to integrate key 802.11bn mechanisms, including MAPC (encompassing Co-TDMA, Co-SR, and Co-BF), NPCA, and DSO, while introducing a modular architecture and an AI-enabled protocol development interface. It supports dynamic subband operation and multi-access point coordination, offering a flexible foundation for protocol validation and forward-looking research. Released under the GNU GPLv3 license as Kom8ndor, the simulator is publicly available on GitHub, providing the research community with an efficient and extensible platform for advancing Wi-Fi 8 studies.
📝 Abstract
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.
