Efficient Beamforming Feedback Information-Based Wi-Fi Sensing by Feature Selection
Published in IEEE Wireless Communications Letters, 2024
In this letter, we first derive a mathematical model of BFI, characterizing its relationship with CSI explicitly, and then develop a closed-form expression of BFI for 2×2 MIMO systems. To enhance the efficiency of BFI-based sensing by selecting only the most informative features, we quantify the sensing capacity of BFI using the Cramer-Rao bound (CRB) and then propose an efficient CRB-based BFI feature selection algorithm.
Beamforming Made Malicious: Manipulating Wi-Fi Traffic via Beamforming Feedback Forgery
Published in ACM MobiCom, 2024
The core idea of BeamCraft involves corrupting beamforming decisions by injecting crafted BFIs that feed an access point (AP) with erroneous information on channel states. Code
