ACM Internet Measurement Conference 2025

@Distributed Systems

Three members attended IMC in Madison, USA and presented two poster papers on (internet) resilience. One demonstrating how amateur‑radio PSKReporter can flag crises before IP‑based metrics, and another correlating outage records with performance data to reveal how different outage types affect South African connectivity.

Our group attended this year's ACM Internet Measurement Conference (IMC) held at the University of Wisconsin-Madison, USA. IMC is the flagship conference focusing on Internet measurement and analysis. Since Internet Measurements is the core research focus of our group, three members are attending. At IMC, we presented two poster papers on (internet) resilience, that are part of the DFG resilient worlds and emergenCITY projects.

Yasin Alhamwy presented our IMC 2025 poster “Beyond IP: Amateur Radio PSKReporter as a Crisis Measurement Tool,” showing how PSKReporter captured a 36% drop during the LA wildfires and signaled hurricane impacts days before IP-based indicators. Curious why non-IP signals matter for crisis monitoring? Check out the PDF.

Further, Yasin Alhamwy also presented our ACM IMC 2025 poster "Power Out, Internet Down? Measuring Internet Resilience in South Africa." This is joint work with Abdalmohimn Alshebane, currently a master student in the Master Program Electrical Communication Engineering (ECE). By correlating detailed outage records with end-user performance by mlab, amateur radio activity, and BGP data, we find performance degrades only during unplanned outages and routing responses vary by month. Curious how outage types shape connectivity? Read the PDF.
