Paper Accepted at MMSys 2022

[May 12th, 2022] Our paper entitled “Swipe Along: A Measurement Study of Short Video Services” was accepted into MMSys 2022 that will be held in Ireland in June 2022. The paper focuses on the performance of various short video services and in particular how those services pre-load content to help improve interactivity. Great work by my student Shangyue and many thanks to our collaborators at AT&T Labs.

S. Zhu, T. Karagioules, E. Halepovic, A. Mohammed, A. Striegel, “Swipe Along: A Measurement Study of Short Video Services” to appear in MMSys 2022.

Office Hours – Spring 2021

[February 1st, 2021] Office hours for the spring semester have been updated and can be found down below the fold.

Scheduled Office Hours

Tuesday: 2-3 PM
Wednesday: 2-4 PM
Friday: 12-1 PM

Help sessions for CSE 30341 and BACS application preparation are available on Wednesday and Thursday evenings from 7-9 PM. If you would like to join the help session, please let me know by 5 PM such that I make sure to have the virtual Zoom room ready to go / am monitoring for joins.

All office hours are virtual via the following Zoom link. As it is admit-based, please nudge me via e-mail if you are waiting too long. Note that only people with a valid ND NetID can join unless arranged in advance.

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.
