[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 10th, 2020] Alas, all good things must come to an end and my sabbatical is officially wrapped up as of this Friday with the start of the spring semester this coming week. This spring, I will be teaching the second iteration of my course on Advanced Wireless Networks and will officially be back on campus full-time at my office in 211B Cushing Hall.
[November 11th, 2019] Brief update as I am well over halfway through my sabbatical this fall. Some interesting new projects in the hopper that we will highlight the projects bake a bit more but I can give a bit of a preview of some of the efforts.
- WiFi Leaf Detection: We are looking how WiFi signals can be used to detect the presence (or lack thereof) leaves on the various trees to help optimize leaf pickup for St. Joseph County (and many other municipalities with burn bans). Some interesting early work taking our monster WiFi capture rig (all 2.4 GHz channels, all 5 GHz channels) done by Al-Amin Mohammed, the lead graduate student on the project. Many thanks to our undergraduate REU student Alexandra Berjarano who kicked off this effort this past summer as part of our Wireless Institute REU site.
- QUIC-enabled FMNC / PASS: We are working on porting our efforts for Fast Mobile Network Characterization (FMNC) and Provider-Assisted Storage Sub-system (PASS) into a unified library riding on QUIC. This should be an interesting adventure and if successful, a very cool unified platform for measurement that leverage QUIC with legacy support for TCP fallback taking advantage of our older work.
- Tesserae: Our Tesserae project continues. Look for some interesting paper updates now that the vast majority of our data collection has wrapped for the effort.
[March 26, 2019] Kudos to the team for having an outstanding site visit for PAWR. While it is still to be determined with respect to us being chosen as a site, the team put together some really top notch work. The overview video and general site for PCAD (PAWR in Collaborative and Autonomous Drones) can be found at: https://sites.google.com/nd.edu/pcad
[March 14, 2019] For our upcoming site visit related to PAWR, our team wrote a visualization tool for RSRP / RSRQ from MobileInsight. Kudos to my student Gonzalo Martinez who wrote an Android app to export Mobile Insight files, ship them over MQTT, parse them, and then re-package them as JSON via MQTT, for the C# visualization app that I crafted together for a demo. We will package up the source code and share it for anyone who might be interested.
[September 1, 2018] For each home game at Notre Dame, our group provides WiFi for the University Relations tent on Irish Green. For a high profile game such as the Michigan game, there are a few more challenges with the crowd density as well as nearby other tests. Our WiFi gear has been newly re-racked in our WiFi “cart” as you can see below.
The WiFi seemed to fare OK though there are certainly some nice improvements that we can make for the next home game both to the cart as well as how we mount gear to the side of the tent. More to come over the next few weeks with respect to the WiFi service and general performance estimates as we start to deploy our Fast Mobile Network Characterization app across the tent and various scattered Raspberry Pis in the tent.
