[January 14th, 2023] New fact check is up on Politifact with regards to discussions of the recent usage of cellular location records with respect to the murders in Idaho versus the data from 2000 Mules.

Applications are due by Friday, March 10th, 2023 at 10 PM EST. Questions may be directed to the BACS Program Director at firstname.lastname@example.org.
[October 10, 2022] Looking ahead to the AY23-24 (academic year) recruiting cycle, our research group is aiming to recruit one or possibly two Ph. D students in the areas of wireless network measurement and wearables. Subject to funding, we may also have some work in network security, particularly blended 4G / 5G / WiFi. We do not envision having funding for post-docs for this coming year (CY23) and are unlikely to have post-doc funding for the next cycle (AY23-24).
In particular, we envision efforts on the following projects or offshoots of these efforts:
Short video: Platforms such as TikTok, Facebook Watch, Instagram Reels and others present fascinating challenges when it comes to QoE. Unlike traditional QoE, short video browsing is tempered by unique circumstances including QoE spanning multiple videos, varying periods of video watching (full or partial viewing), and highly dynamic network performance. We are interested in studying the underlying tradeoffs associated with how best to pre-stage, adapt quality, and handle various dynamics in such scenarios.
Network performance: One of the major thrusts of our research group over the past few years has been to study how to better measure the network through intentional, structured packet trains injected at the server to elicit a rapid, improved understanding of network performance characteristics. Newly emerging networks such as 5G, WiFi 6E, CBRS, and mmWave introduce intriguing new challenges for measurement.
Wearables and pervasive computing: The new capabilities of wearable devices continue to advance offering increased lifetime, sensing capabilities, and unobtrusive form factors. Our research group is interested on how COTS or COTS wearables plus enhancements can be better leveraged to bring robust quantitative measurement to previously unexplored aspects of human physiological and overarching social interactions.
If you might be interested in joining our research group, we encourage you to apply to join the graduate program at the University of Notre Dame. Depending on your area of interest, you might also want to check out the research groups of Spyros Mastorakis (networking – joining ND in January 2023), Toby Li (human computing interface / mobile apps), and Taeho Jung (security).
Many thanks to Lucy Li for the Twitter recommendation to post this to help new graduate students.
[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.
[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.
[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.
[January 26th, 2020] One item that comes up every once in a while is our old WeHab project which brought to bear low-cost peripherals for the purpose of helping out with stroke rehabilitation / balance impairment. For those who are so inclined, you are welcome to download the executables of the code along with instructions via Google Drive. Note that the executables come as is and may be a bit dated.
[January 23rd, 2020] Our journal paper entitled “A game-theoretic analysis on the economic viability of mobile content pre-staging” is now live via the Wireless Networks journal. The paper focuses on mobile content pre-staging with an eye towards whether or not said pre-staging is solely beneficial to the provider or pre-staging gains are shared with the end-user. This is related to our on-going work NSF grant focusing on PASS (Provider Accessible Storage Subsystem) as this was a pre-cursor paper to that effort that we published at the INFOCOM Workshop on Smart Data Pricing back in 2016. This particular paper offers some nice new insights and an expanded analysis relative to the shorter workshop paper. Kudos to Prof. Liao (my former student, now a tenured professor at Central Michigan) and Prof. Li for their fantastic work on this effort.
- The first paper entitled “Improved Sleep Detection Through the Fusion of Phone Agent and Wearable Data Streams” focuses on the extent to which phone agent data, specifically the screen on / off state, impacts the accuracy of time to bed and wake time as observed by the wearable.
- The second paper entitled “On the Quality of Real-world Wearable Data in a Longitudinal Study of Information Workers” explores the quality of wearable data in terms of data consistency, interruptions / missing data, and charging behavior from the Garmin vivoSmart 3.
Both of these efforts are drawn from our data for Tesserae with one presented by Gonzalo and the other presented by Steve at the WristSense workshop at IEEE PerCom this year. Congrats again to Gonzalo and Steve on a job well done in driving these papers!
