Paper Accepted – Passive WiFi

[December 3, 2020] Our journalized version of the paper on leveraging passive WiFi characteristics for determining the available bandwidth was recently accepted to appear in the IEEE Internet of Things journal.

Very cool paper that leverages the spacing of plaintext block acknowledgements (ACKs) for the purpose of inferring the utilization on a given wireless link. In the paper, we show not only the feasibility of leveraging block ACKs for inferring bandwidth but we also demonstrate that such an approach would be viable during the normal WiFi scanning process (e.g. detecting block ACKs during a WiFi scanning sweep looking for nearby APs) is enough time to reasonably infer the available bandwidth.

Off to Dublin in June for ICC 2020

[January 27, 2020] Will be off to Dublin, Ireland in June 2020 for ICC 2020 as our paper on using aggregation as an indication of available bandwidth via purely passive estimations was accepted to the CQRM symposium.  If I recall, it was roughly 20 years ago that I went to my first “big” conference attending ICC when it was in Helsinki, Finland.  One out of two papers in on this go round to ICC 2020.  Wicked cool paper by my former Ph. D student Dr. Lixing Song with an assist from my current Ph. D student Al-Amin Mohammed to get it over the finish line.  Bit more on the paper after the break.
