Sabbatical Update

[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.

Papers at CHI 2019

[May 14, 2019] We had two papers appear at CHI in the Case Studies track.  One paper was a general overview of the Tesserae study and the other was an overview of our publicly accessible social media corpus related to Tesserae (all participants opted in who agreed to share data).  Both papers are accessible via the CHI website.

PCAD Site is Operational

[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 

Mobile Insight Visualization

[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.

Panel on Cyber Security / Microgrids

[March 14, 2019] I gave a small talk at the monthly luncheon for our Energy Center on cyber security, micro grids, and the Internet of Things.  Nothing too intense as it was a fairly quick talk but I have attached my slides here if anyone is particularly interested.  Most importantly, I would strongly recommend pinging my adviser, Manimaran Govindarasu, who is the one who really works on this topic.
