5G encompasses features such as Ultra-Reliable Low Latency Communication (URLLC) and Massive Machine Type Communication (mMTC) to minimize delays and connect numerous devices. This requires an Active User Detection (AUD) scheme, necessitating real-time detection by the Base Station (BS). Maximum Likelihood (ML) is the most efficient for AUD, but it...
The new 5G’s wireless networks have started to be deployed all around the world. With them, a large spectrum of services are about to emerge, resulting in new stringent requirements so that 5G targets performances exceed that of 4G by a factor of 10. The services are enhanced mobile broadband (eMBB), ultra reliable and low-latency communication (uR...
Topological Interference Management (TIM) allows studying the Degrees of Freedom (DoF) of partially connected linear interference communication networks, where the Channel State Information at the Transmitter (CSIT) is restricted to the topology of the network, i.e., a knowledge of which interference links are weak and which are strong. In this the...
Autonomous unmanned aerial vehicles (UAVs), spurred by rapid innovation in drone hardware and regulatory frameworks during the last decade, are envisioned for a multitude of applications in service of the society of the future. From the perspective of next-generation wireless networks, UAVs are not only anticipated in the role of passive cellular-c...
Dans cet article nous nous intéressons au problème de la diffusion dans les réseaux sans fil. Nous étudions un modèle particulier de système où les noeuds disposent localement d'un espace de mémoire constant leur permettant d'éviter des collisions lors de transmissions concurrentes. Nous étudions deux variantes de la diffusion : diffusion avec et s...
Also known as the Internet of Things (IoT), the proliferation of connected objects offers unprecedented opportunities to consumers. From fitness trackers to medical assistants, through smarthome appliances, the IoT objects are evolving in a plethora of application fields. However, the benefits that they can bring to our society increase along with ...
Connected and Autonomous vehicles (CAV) must have adequate reliability and safety requirements in uncertain environments with complex circumstances. Sensor technology, actuators and artificial intelligence (AI) are constantly and rapidly evolving, thus enabling further development of self-driving vehicles, and increasing the automation of driving. ...
Vivre des moments exceptionnels, connaître des sensations fortes, du bien-être, nous épanouir, font souvent partie de nos rêves ou aspirations. Nous choisissons des moyens divers pour y arriver comme le jeu. Que le joueur recherche l’originalité, les défis, la découverte, une histoire, ou d’autres buts, ce sont des états émotionnels qui sont l’obje...
Ce papier présente une technique pour faire évader des données via un réseau à synchronisation temporelle sans nécessiter de privilèges particuliers sur l'appareil faisant échapper le secret. Pour cela nous proposons l'utilisation de la dérive d'horloge causée par la température de l'oscillateur. Nous proposons une implémentation en utilisant un ré...
The massive increase in cellular traffic poses serious challenges to all actors concerned with wireless content delivery. While network densification provides access to additional users, high-speed and high-capacity backhaul connections are expensive. Caching popular content at the network edge promises to offload user traffic from these congestion...
