Wi-Fi Meets ML: A Survey on Improving IEEE 802.11 Performance with Machine Learning
Szymon Szott, Katarzyna Kosek-Szott, Piotr Gawłowicz +4
Wireless local area networks (WLANs) empowered by IEEE 802.11 (Wi-Fi) hold a dominant position in providing Internet access thanks to their freedom of deployment and configuration…
Wi-Lo: Emulating LoRa using COTS WiFi
Piotr Gawlowicz, Anatolij Zubow, Falko Dressler
We present Wi-Lo, which allows to convert an ordinary 802.11 (WiFi) access point into an internet of things (IoT) gateway supporting the low-power wide area network (LPWAN) technol…
Distributed Learning for Proportional-Fair Resource Allocation in Coexisting WiFi Networks
Piotr Gawłowicz, Jean Walrand, Adam Wolisz
In this paper, we revisit the widely known performance anomaly that results in severe network utility degradation in WiFi networks when nodes use diverse modulation and coding sche…
On Phase Offsets of 802.11ac Commodity WiFi
Anatolij Zubow, Piotr Gawlowicz, Falko Dressler
We analyze the phase offsets between RF chains of modern IEEE 802.11ac chips. We investigate both the 2.4 and 5GHz bands on a per OFDM subcarrier level. Results reveal that the pha…
Practical MIMO for Visible Light Communication
Piotr Gawłowicz, Elnaz Alizadeh Jarchlo, Anatolij Zubow
Visible Light Communication (VLC) is seen as a complementary wireless technology to Radio Frequency (RF). However, VLC is very sensitive to the signal blockage and suffers from sha…
WoV: WiFi-based VLC testbed
Piotr Gawłowicz, Elnaz Alizadeh Jarchlo, Anatolij Zubow
We present a complete Visible Light Communications (VLC) transceiver system consisting of low-cost Commercial-Off-The-Shelf (COTS) components. In particular, we show that COTS IEEE…
OfdmFi: Enabling Cross-Technology Communication Between LTE-U/LAA and WiFi
Piotr Gawłowicz, Anatolij Zubow, Suzan Bayhan +1
Despite exhibiting very high theoretical data rates, in practice, the performance of LTE-U/LAA and WiFi networks is severely limited under cross-technology coexistence scenarios in…
Deep Learning for Cross-Technology Communication Design
Anatolij Zubow, Piotr Gawłowicz, Suzan Bayhan
Recently, it was shown that a communication system could be represented as a deep learning (DL) autoencoder. Inspired by this idea, we target the problem of OFDM-based wireless cro…
ns3-gym: Extending OpenAI Gym for Networking Research
Piotr Gawłowicz, Anatolij Zubow
OpenAI Gym is a toolkit for reinforcement learning (RL) research. It includes a large number of well-known problems that expose a common interface allowing to directly compare the…
XZero: On Practical Cross-Technology Interference-Nulling for LTE-U/WiFi Coexistence
Anatolij Zubow, Piotr Gawłowicz, Suzan Bayhan
LTE-U/WiFi coexistence can be significantly improved by placing so-called coexistence gaps in space through cross-technology interference-nulling (CTIN) from LTE-U BS towards WiFi…
LtFi: Cross-technology Communication for RRM between LTE-U and IEEE 802.11
Piotr Gawłowicz, Anatolij Zubow, Adam Wolisz
Cross-technology communication (CTC) was proposed in recent literature as a way to exploit the opportunities of collaboration between heterogeneous wireless technologies. This pape…
UniFlex: Accelerating Networking Research and Experimentation through Software-Defined Wireless Networking
Piotr Gawłowicz, Anatolij Zubow, Mikolaj Chwalisz +1
Classical control and management plane for computer networks is addressing individual parameters of protocol layers within an individual wireless network device. We argue that this…
NxWLAN: Neighborhood eXtensible WLAN
Piotr Gawłowicz, Sven Zehl, Anatolij Zubow +1
The increased usage of IEEE 802.11 Wireless LAN (WLAN) in residential environments by unexperienced users leads to dense, unplanned and chaotic residential WLAN deployments. Often…
