Mobile Web and App QoE Monitoring for ISPs -from Encrypted Traffic to Speed Index through Machine Learning
Web browsing is one of the key applications of the Internet. In this paper, we address the problem of mobile Web and App QoE monitoring from the Internet Service Provider (ISP) perspective, relying on in-network, passive measurements. Our study targets the analysis of Web and App QoE in mobile devices, including mobile browsing in smartphones and t...
Social Influencer Selection by Budgeted Portfolio Optimization
Influencer marketing has become in the recent years a thriving industry that includes more than 1120 agencies worldwide and with a global market value expected to reach 15 billion dollars by 2022. The advertising problem that such agencies face is the following: given a monetary budget find a set of appropriate influencers on a social platform and ...
Data Reduction and Frame Rate Adaptation in WVSN
Wireless Video Sensor Networks (WVSNs) are becoming one of the most used technologies for surveillance and livestock monitoring. They are composed of small embedded video and camera motes that capture video frames periodically and send them to a specific node called a sink. Sending all the captured images to the sink consumes a lot of energy on eve...
Performances 5G: étude comparée en zones rurales et urbaines
Ce rapport propose une méthodologie permettant de comparer les débits moyens obtenus par les utilisateurs 5G en zone rurale et en zone urbaine. Ces environnements sont caractérisés par des conditions de propagation radio et des choix de paramétrage de la technologie 5G spécifiques à chacune des zones. Par exemple, en zone rurale, la propagation rad...
Unifying LoRaWAN Networks by Enabling the Roaming Capability (short paper)
LoRaWAN is a promising enabling technology for connected things. Nowadays, it is largely used in many application areas thanks to its relevant features such as long-range, low-cost, and low power consumption. However, as with all wireless technologies, mobility remains a major concern bringing end-devices out of their home operator coverage. In thi...
Slice Aware Non Terrestrial Networks
With the recent integration of Non Terrestrial Networks (NTNs) into 3GPP Release 17, 5G networks are expected to benefit from the NTN large coverage area. This integration will help mobile terrestrial networks reach a worldwide coverage. However, this ultimate ubiquity also comes with its set of challenges to overcome. One of the main issues is the...

Optimal Prefetching in Random Trees
We propose and analyze a model for optimizing the prefetching of documents, in the situation where the connection between documents is discovered progressively. A random surfer moves along the edges of a random tree representing possible sequences of documents, which is known to a controller only up to depth d. A quantity k of documents can be pref...
EnosLib: A Library for Experiment-Driven Research in Distributed Computing
Despite the importance of experiment-driven research in the distributed computing community, there has been little progress in helping researchers conduct their experiments. In most cases, they have to achieve tedious and time-consuming development and instrumentation activities to deal with the specifics of testbeds and the system under study. In ...
