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.

Virtual Office Hours

[August 10, 2020] Office hours will be held virtually until mid-September unless specifically requested for in-person meetings. For in-person meetings, masks are required and the office area is limited to a maximum capacity of two. All in-person meetings will be held in 211B Cushing due to logistical issues associated with opening the CDT space in O’Shaughnessy.

Fall 2020 Office Hours

[July 12, 2020] Fall 2020 office hours will be as follows:

Monday – 1-2 PM – 211 Cushing
Wednesday – 9-11 AM – CDT space in O’Shaughnessy
Friday – 8:15 – 11 AM – Dedicated appointment block in either Cushing / O’Shaughnessy (typically Cushing)

Friday mornings are a dedicated block for scheduled appointments with students (BACS, CSE) that are intentionally excluded from recurring meetings.  Simply shoot myself or one of the admins a note (Tiffanie Sammons if you are coming from the CSE side or Claire Shelly if you are BACS or interested in the BACS) at least the day before by COB (Close of Business) and you as a student can schedule an appointment.  Depending on where the appointments are best suited, I will hold them either in O’Shaughnessy or in Cushing.

The Monday and Wednesday times are open to walk-ins, no appointment needed.

WristSense / EuroViz

[March 30th, 2020] Two updates with regards to papers.  Our short paper for EuroViz 2020 entitled “Characterizing Exploratory Behaviors on a Personal Visualization Interface Using Interaction Logs” was accepted to appear.  Congrats to Poorna on her hard work in driving the paper through.

Our paper presented last week at WristSense 2020 entitled “Improved Sleep Detection Through the Fusion of Phone Agent and Wearable Data Streams” won Honorable Mention for the Apple Best Paper Award.  Congrats to Stephen on the presentation and Gonzalo on their work for the paper.

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.
