With Fifth Generation (5G) Networks, multiple heterogeneous services are supported such as the enhanced Mobile BroadBand (eMBB) service characterized by high throughput demand, the Ultra-Reliable Low-Latency Communications (URLLC) service requiring a low latency and the massive Machine-Type Communications (mMTC) service favoring a high density of c...
In this work, we introduce a novel automated technique for protocol design known as protocol emergence. In the context of protocol emergence, network nodes engage in the exchange of control messages to coordinate the delivery of data across the network, all without a predefined agreement on the meaning of these messages. This approach can be viewed...
L’informatique en périphérie est un paradigme émergent au sein de l’Internet des Objets (IoT) et complémentaire à l’informatique en nuage. Ce paradigme propose l’implémenta- tion de serveurs de calcul situés à proximité des utilisateurs, réduisant ainsi la pression et les coûts de l’infrastructure réseau locale. La proximité avec les utilisateurs s...
This thesis introduces new models and solution methods for the Dial-A-Ride Problem (DARP). This work is applied to the regular transportation of disabled children between their homes and medico-social institutions. To ensure a high quality of service and low costs, the transportation must be carried out as efficiently as possible. None of the metho...
Cette thèse s'intéresse au déploiement d'une architecture de communication V2X afin de faciliter l'insertion de véhicules autonomes dans une infrastructure réseau hétérogène. L'ajout de connectivité permettrait à une grande diversité d'applications de satisfaire leurs contraintes strictes de performance, en allégeant la charge induite sur les unité...
This dissertation considers radio and computing resource allocation in future radio access networks and more precisely Cloud Radio Access Network (Cloud-RAN) and Open Radio Access Network (Open-RAN). In these architectures, the baseband processing of multiple base stations is centralized and virtualized. This permits better network optimization and...
The Fifth Generation-New Radio (5G-NR) introduced the concept of slicing to target different types of services. We consider in this thesis vehicular traffic, with vehicles sending two types of flows: enhanced Mobile BroadBand (eMBB) and Ultra-Reliable and Low Latency Communications (URLLC). These flows are transported in two different slices, the f...
The ability of microbes to colonize the most improbable places can be partly attributed to the efficient coordination between growth and metabolism. Over the last 50 years, the relationship between growth and the environment has been intensely studied, and has lead to general empirical relationships or 'growth laws'. In most studies, however, bacte...
Nous introduisons des techniques d'allocation de ressources pour un problème où (i) les agents expriment des demandes d'obtention de lots d'objets sous forme de graphes acycliques dirigés compacts pondérés (chaque chemin dans ces graphes est un lot dont l'évaluation est la somme des poids des arêtes traversées), et (ii) les agents ne demandent pas ...
