Pr. Didier Donsez of Ensimag
Les réseaux longue distances pour l’Internet des Objets (NB-IoT, LoRa/LoRaWAN …)
Biography:
Didier Donsez is full professor in Computer Sciences at Université Grenoble Alpes (Grenoble, France) since 2007. He was assistant professor in Computer Sciences at Université de Valenciennes (France) from 1996 to 2001 and at Université Joseph Fourier (Grenoble, France) from 2001 to 2007. He earned a doctorate (Ph.D) in Computer Sciences (1994) at University of Paris VI: Pierre et Marie Curie and a HDR in Computer Sciences (2006) at Université Joseph Fourier. His research labs is the LIG (Laboratoire d'Informatique de Grenoble) [https://www.liglab.fr], ERODS team [http://erods.liglab.fr]. He teaches in the Computer Sciences departement at Polytech Grenoble (engineering school). His research area is middlewares and software engineering for the internet of things (IoT) since 20 years. His current topics are LPGAN, SatIoT and Artificial Intelligence at Extreme Edge. He is the principal investigator of the Thingsat project, an in-orbit research vehicle for benchmarking LoRa© modulation in SatIoT applications.

Assoc. Prof. Olivier Alphand of Ensimag
Réseaux satellites pour l’Internet des Objets
Biography:
Olivier ALPHAND is associate professor in Computer Networks at Grenoble INP - Université Grenoble Alpes, and member of the LIG (Laboratoire d'Informatique de Grenoble) lab, in the Drakkar team since 2006.
He teaches at Ensimag (french engineering school) since 2006 and his research theme, since 2003, is centered on the study and development of network protocols in wireless networks in the broad sense (from WSN (Wireless Sensor Network) (10m/100kbps) to satellite (36000km/Gbps) via WiFi (100m/Mbps) or more recently LPWAN (10km/1kbps)).
His work focuses on the self-organization of WSNs through, for example, the adaptation of routing and access protocols as well as their duty-cycle to their local traffic and energy conditions. Another aspect of his work concerns the development of distributed communication scheduling algorithms to optimize the data flow in WSNs. In order to validate these protocols, real experiments have taken an important part to overcome the limitations of simulators. This requires on the one hand to port protocols on real nodes and on the other hand to deploy this code and experiment on platforms such as IoT-LAB. An important work of characterization of the behavior of wireless links accompanied these experiments in order to better choose the metrics for the developed protocols.
Another part of his activity is focused on LPWAN random access methods that could benefit cellular networks for IoT (Internet of Things) such as LoRa networks (very low data rate (1kbps) but very long range (10km) and densely connected (100.000 objects/base station)). He is currently focusing on the use of LoRa technology in new space with especially the development of a payload for benchmarking LoRa modulation in a cubesat (Thingsat project).
