Low-power wireless networks and the Internet of Things
How constrained radio networks behave at scale: the capacity of LoRaWAN and LR-FHSS, medium access, energy consumption, and the protocol design that connects small devices to the Internet.
Drakkar group
Networks and distributed systems, Laboratoire d'Informatique de Grenoble
The Drakkar team studies computer networks, from the radio link up to the protocols and services that run across the Internet. We are part of the Laboratoire d’Informatique de Grenoble.
Internet measurement and security
Measuring the deployed Internet to find where it is fragile: DNS misconfiguration and abuse, the domain name and certificate ecosystems, and the infrastructure behind phishing campaigns.
