Philippe CIBLAT<\/strong>, Professeur, T\u00e9l\u00e9com Paris, FRANCE – Directeur de these R\u00e9sum\u00e9 :<\/strong><\/p>\n\n\n\n Les d\u00e9fis pos\u00e9s par le nombre croissant d’appareils connect\u00e9s, la forte consommation d’\u00e9nergie et l’impact environnemental dans les r\u00e9seaux sans fil d’aujourd’hui et de demain retiennent de plus en plus l’attention. De nouvelles technologies telles que le cloud mobile de p\u00e9riph\u00e9rie (Mobile Edge Computing) ont vu le jour pour rapprocher les services en nuage des appareils et rem\u00e9dier \u00e0 leurs limitations en mati\u00e8re de calcul. Le fait de doter ces appareils et les n\u0153uds du r\u00e9seau de capacit\u00e9s de r\u00e9colte d’\u00e9nergie (Energy Harvesting) est \u00e9galement prometteur pour permettre de consommer de l’\u00e9nergie \u00e0 partir de sources durables et respectueuses de l’environnement. En outre, l’acc\u00e8s multiple non orthogonal (Non-Orthogonal Multiple Access) est une technique essentielle pour am\u00e9liorer l’efficacit\u00e9 spectral mobile. Avec l’aide des progr\u00e8s de l’intelligence artificielle, en particulier des mod\u00e8les d’apprentissage par renforcement (Reinforcement Learning), le travail de th\u00e8se porte sur la conception de politiques qui optimisent conjointement l’ordonnancement et la d\u00e9charge de calcul pour les appareils dot\u00e9s de capacit\u00e9s EH, les communications compatibles avec le NOMA et l’acc\u00e8s MEC. En outre, lorsque le nombre d’appareils augmente et que la complexit\u00e9 du syst\u00e8me s’accro\u00eet, le regroupement NOMA est effectu\u00e9 et l’apprentissage f\u00e9d\u00e9r\u00e9 (Federated Learning) est utilis\u00e9 pour produire des politiques RL de mani\u00e8re distribu\u00e9e. Les r\u00e9sultats de la th\u00e8se valident la performance des politiques RL propos\u00e9es, ainsi que l’int\u00e9r\u00eat de l’utilisation de la technique NOMA.<\/p>\n\n\n\n Abstract :<\/strong><\/p>\n\n\n\n The challenges posed by the increasing number of connected devices, high energy consumption, and environmental impact in today\u2019s and future wireless networks are gaining more attention. New technologies like Mobile Edge Computing (MEC) have emerged to bring cloud services closer to the devices and address their computation limitations. Enabling these devices and the network nodes with Energy Harvesting (EH) capabilities is also promising to allow for consuming energy from sustainable and environmentally friendly sources. In addition, Non-Orthogonal Multiple Access (NOMA) is a pivotal technique to achieve enhanced mobile broadband. Aided by the advancement of Artificial Intelligence, especially Reinforcement Learning (RL) models, the thesis work revolves around devising policies that jointly optimize scheduling and computational offloading for devices with EH capabilities, NOMA-enabled communications, and MEC access. Moreover, when the number of devices increases and so does the system complexity, NOMA clustering is performed and Federated Learning is used to produce RL policies in a distributed way. The thesis results validate the performance of the proposed RL-based policies, as well as the interest of using NOMA technique.<\/p>\n","protected":false},"excerpt":{"rendered":" L’Ecole doctorale :
