Orangel Azuaje Contreras defended his PhD thesis "End-to-End Delay Guarantees in Communication Networks: Bridging the Gap Between Analytical Methods and Experimentation" as part of the MAP-Tele Doctoral Program at Faculdade de Engenharia da Universidade do Porto. It was an exciting discussion with the jury: James Gross, Marília Curado, Daniel Corujo, , Luís ALmeida, Aníbal Ferreira.

We quantified trade offs between communication range and latency bounds for data collection over WiFi using network calculus. Also, we built a tool for long term measurement of end-to-end latency, proposed an automated method for applying extreme value theory to e2e latency tails in blackbox networks, and established the connection between 5G RAN parameters and a sawtooth pattern in the uplink latency.
