Texto completoThe pervasiveness of mobile devices equipped with internet connectivity and positioning systems leads us to regard them as a valuable resource to leverage. In this thesis, we tackle the use of mobile devices from a new perspective. We consider the extension of the capacity of the MEC by using the available resources of mobile devices beyond the edge of the infrastructure network. The goal is to leverage their untapped resources to process computation on behalf of the MEC in a distributed way. It is fundamental for the MEC to be aware of its operating environment to rely on mobile nodes. In the first part of the thesis, we have focused on the temporal availability of beyond-the-edge resources. We chose to investigate the co-location of terminals and analyze their persistence in a cell. Then, we turn our attention to task allocation. We shift the focus on the spatio-temporal aspect by quantifying the resources that a cell can provide to perform a MEC task. We estimate the potential amount of computational tasks performed by nodes based on the cumulative presence time in a given cell and a given completion delay. Results provide insight into the possibilities of offloading computing tasks on mobile nodes. Furthermore, it allows knowing the locations where it is advisable to offload tasks and the time duration of tasks offloadable

Texto completoThis thesis is the result of a collaboration between DAVID Laboratory and Nokia Bell Labs France.The original idea is to find algorithmic solutions to deterministically manage periodic flows in networks in order to control and minimize the transmission time, called latency. One of the objectives of 5G (C-RAN, for Cloud Radio Access Network) is to centralize the calculation units of the radio antennas of telecommunications networks (called Radio Access Network) in the same computer center (the Cloud). The network between the computing center and the antennas must be able to satisfy the latency constraints imposed by the protocols.We define the problem of finding a periodic scheduling for messages so that they never compete for the same resource, and prove that the different variants of the problem studied are NP-complete. We first study the problem for a particular topology in which all the streams share the same link. We first propose polynomial algorithms of increased sophistication, and FPT algorithms that allow us to find a solution when the number of routes is reasonable, which is the case for C-RAN networks.Since the algorithms developed in this first part are not directly adaptable to more general topologies, we then propose a canonical form to the problem which allows us to define an efficient neighborhood notion for local search heuristics (hill climbing, tabu search, simulated annealing). We use this canonical form to define an efficient Branch and Bound algorithm when the number of routes is moderate.We also propose a performance evaluation of the proposed solutions compared to current flow management solutions, and show that our model is feasible in practice thanks to new equipment under development

Texto completoThe optical access network is booming, especially with the massive deployment of FTTH connecting clients’ home and antenna sites for the incoming 5G. The fiber’s popularization and the transformation of data consumption drive the bitrate growth. Many solutions are proposed. In this thesis, the passive optical network’s (PON) bitrate growth will be studied along three axes :• PAM4 to reuse 10GHz optoelectronical components to reach 25Gbit/s. This four levels modulation format is more bandwidth efficient than NRZ and it allows to transmit two bitratesas the same time on a PON tree. Within the first chapter, optical amplification is studied to enhance the optical budget for a PAM4 transmission. Last part of the chapter presents asimulation based on the real-time experiment to simulate PAM8.• Three vendors’ solutions for the throughput growth. The first prototype is based on theNG-PON2 standard and its PtP WDM option. The second prototype demonstrates how to transmit 25Gbit/s with duobinary and vestigial side band modulation. The last prototype illustrates a youthful solution for 5G fronthauling with a PtP WDM system transmitting at 25Gbit/s.• Equalization in PON’s context. Signal processing and equalization are common in optical transport links. With the throughput rising, equalization in access network seems indispensable. In the chapter, an implementation of equalization is proposed congruently with point-to-multipoints PON application and compliantly with access network’s cost needs and topology
Attencourt, Boris. "Les intellectuels à l’épreuve de la visibilité : faire carrière au-delà de l’université (1970-2015)". Thesis, Paris, EHESS, 2021. http://www.theses.fr/2021EHES0009.
Texto completoThis thesis focuses on the channels through which a fraction of intellectuals become visible (quality press, intellectual journals, think tanks, conference venues, cultural radio and television broadcasts, publishing houses, etc.). Combining reference to legitimate culture, accessibility and action, such circuits developed at the end of the 1970s until they established themselves as the space for the public value of ideas and their carriers.The thesis therefore focused on the issues of visibility for intellectuals during the period from the 1970s to the mid-2010s and shows that careers in external recognition do not take place after or outside the university but rather at the same time. In order to explain this configuration of intellectual notoriety, we have resorted here to a sociohistorical and multilevel approach of the circuits of visibility where it is a question of apprehending their institutions, producers and audiences. However, the places of scholarly conferences intended for a large public because they occupy a cardinal place within the circuits of intellectual visibility have proven to be a particularly effective entry point for empirically reconstituting the channels that have been woven between the margins. academia, senior administration and the media. A multisite ethnography of the conferences (N = 15) which resulted in a large body of observations (N = 97) thus paved the way for a whole set of explorations of these circuits at the micro and macro scales. Through long-term immersions and a participant observation which made it possible to collect substantial empirical material (observations, interviews and archives), we endeavored to reconstruct the genesis and then the trajectory of exemplary institutions (Beaubourg, the International College of Philosophy and the University of all knowledge). We conducted interviews with producers (N = 18) and, in connection with this category of interviewees, cultural intermediaries and their back-up staff (N = 9). In the qualitative register, we also carried out analyzes of controversies (Billeter / Jullien and Badiou / Finkielkraut). In addition, many quantitative treatments, including factorial and network analyzes, were carried out based on a prosopography of producers divided between natural sciences (N = 64) and human and social sciences (N = 195) following a sampling representative of speakers. With regard to reception, the focus was placed on conference listeners by diversifying the investigation methods: to the observations collected from the public during all phases of the conferences, interviews were added (N = 27) and several questionnaire surveys conducted by us within the International College of Philosophy (N = 330) and the University of All Knowledge (N = 285, 157 and 183).On the basis of these various surveys, the thesis takes account of the monopoly exercised by these circuits of cultural celebration in the access to public notoriety of intellectuals which led to the formation of a heteronomous space where social capital takes precedence over autonomous species. cultural capital. Consequently, this space and the elite of the spirit which is devoted to it participate in the renewal of the modes of domination of the dominant class since the 1980s. If this work is a contribution to the sociology of intellectuals and sciences, to that of the elites and the media, to that of cultural taste and consumption and to methodological reflections around the articulation of levels, he would also like to contribute to the analysis of ideological and academic forms of intellectual doxa
Diakite, Aboubakar. "Commerce informel des hydrocarbures au Bénin". Thesis, Strasbourg, 2016. http://www.theses.fr/2016STRAG043.
Texto completoFirst of all on a small scale, then further along, on a much larger scale, the kpayo trade which means smuggling of gas and other oil products from Nigeria to Bénin, depend on almost 100 000 persons living on this sale activity. This trade might be quite different if gas transported by means of ships on the sea, by the river, or by scooters or trucks on the road. This kind of informal trade gives way to different kinds of odd jobs we mention in the PHD: bringing the jerrycans to the beach, reshaping scooters and trucks in a garage. Most of all this illicit activity needs some kind of a kinship network and political pull among the police and customs officers of the Republic. Empirical research has been done in different fields such as a gas station, a seaside village, a market on the country border, a landing stage, a warehouse, it led to the comprehension of the way smugglers are supplied. I was thus able to understand the process by which gas was transported from Nigeria to the Republic of Bénin, and see all the byways the smugglers are used to take, and the risks taken all along the journey. I examined the interaction process between the racketeers and the police when they passed a checkpoint; see how the markets were busy, and last managed to see how the the different roles of subjects interact. The racketeers networks analysis, life stories, different action strategies, the way they accumulate and the study of informal economy related to law contribute in this PhD to an essay in economic- anthropology with geographic standpoints, and a sociological analysis of precarious lives and Big Shots
Ropitaux, Marc. "Le Root Extracellular Trap (RET), un réseau au coeur de la défense racinaire : caractérisation moléculaire et fonctionnelle chez deux légumineuses, Glycine max (Merr.) L. et Pisum sativum (L.)". Thesis, Normandie, 2018. http://www.theses.fr/2018NORMR098.
Texto completoIn higher plants, the RET (Root Extracellular Trap) is a complex made up of border cells and secretions, released by root tips and believed to play a central role in biotic and abiotic stress tolerance. This structure is quite similar to the Neutrophil Extracellular Trap (NET) known as one of the first lines of defense in mammals, able to trap and kill microbial pathogens. RET secretions consist of high and low-molecular weight compounds including cell wall polysaccharides, proteoglycans and secondary metabolites. They also contain a variety of anti-microbial proteins and extracellular DNA much like the NET. During my thesis work, we investigated the release and morphology of root border cells in soybean (Glycine max (Merr) L.) using light and scanning electron microscopy. The molecular composition of the mucilage was also investigated using immunocytochemistry, anti-cell wall glycan antibodies and confocal microscopy. Immunocytochemistry was also applied to pea (Pisum sativum L.) border cells and secretions to examine the occurrence of specific polysaccharides. We also studied the impact of soybean RET on the soilborne pathogens, Phytophthora parasitica and Aphanomyces euteiches. Our findings showed that root tips of soybean released three border cell morphotypes all of which secreted substantial amounts of mucilage. Immunocytochemical data showed that mucilage was enriched in pectin and the two hemicellulosic polysaccharides xyloglucan and heteromannan. Mucilage also contained cellulose, histone and extracellular DNA. Interestingly, the structural polysaccharides formed a fibrous network surrounding the cells and holding them together, supporting their role in maintaining mucilage architecture and integrity. In addition, we found that xyloglucan and cellulose were also secreted into the mucilage of pea, connecting border cells together. Finally, our findings revealed that RET prevented P. parasitica zoospores from colonizing soybean root tip, by stopping their penetration and inducing their death. Overall the study revealed novel insights into the composition, structure and function of plant RETs. Currently, the RET is much less studied than its mammal counterpart, the NET, but structural and functional similarities exist between these two traps. Interestingly, similarities do also exist between the RET and other important biological complexes, including bacterial biofilms and seed mucilage, that deserve to be further investigated and compared in the context of immunity
Arora, Sagar. "Cloud Native Network Slice Orchestration in 5G and Beyond". Electronic Thesis or Diss., Sorbonne université, 2023. http://www.theses.fr/2023SORUS278.
Texto completoNetwork Function Virtualization (NFV) is the founding pillar of 5G Service Based Architecture. It has the potential to revolutionize the future mobile communication generations. NFV started long back in 2012 with Virtual-Machine (VM) based Virtual Network Functions (VNFs). The use of VMs raised multiple questions because of the compatibility issues between VM hypervisors and their high resource consumption. This made containers to be an alternative network function packaging technology. The lightweight design of containers improves their instantiation time and resource footprints. Apart from network functions, containerization can be a promising enabler for Multi-access Edge Computing (MEC) applications that provides a home to low-latency demanding services. Edge computing is one of the key technology of the last decade, enabling several emerging services beyond 5G (e.g., autonomous driving, robotic networks, Augmented Reality (AR)) requiring high availability and low latency communications. The resource scarcity at the edge of the network requires technologies that efficiently utilize computational, storage, and networking resources. Containers' low-resource footprints make them suitable for designing MEC applications. Containerization is meant to be used in the framework of cloud-native application design fundamentals, loosely coupled microservices-based architecture, on-demand scalability, and high resilience. The flexibility and agility of containers can certainly benefit 5G Network Slicing that highly relies on NFV and MEC. The concept of Network slicing allows the creation of isolated logical networks on top of the same physical network. A network slice can have dedicated network functions or its network functions can be shared among multiple slices. Indeed, network slice orchestration requires interaction with multiple technological domain orchestrators, access, transport, core network, and edge computing. The paradigm shift of using cloud-native application design principles has created challenges for legacy orchestration systems and the ETSI NFV and MEC standards. They were designed for handling virtual machine-based network functions, restricting them in their approach to managing a cloud-native network function. The thesis examines the existing standards of ETSI NFV, ETSI MEC, and network service/slice orchestrators. Aiming to overcome the challenges around multi-domain cloud-native network slice orchestration. To reach the goal, the thesis first proposes MEC Radio Network Information Service (RNIS) that can provide radio information at the subscriber level in an NFV environment. Second, it provides a Dynamic Resource Allocation and Placement (DRAP) algorithm to place cloud-native network services considering their cost and availability matrix. Third, by combining NFV, MEC, and Network Slicing, the thesis proposes a novel Lightweight edge Slice Orchestration framework to overcome the challenges around edge slice orchestration. Fourth, the proposed framework offers an edge slice deployment template that allows multiple possibilities for designing MEC applications. These possibilities were further studied to understand the impact of the microservice design architecture on application availability and latency. Finally, all this work is combined to propose a novel Cloud-native Lightweight Slice Orchestration (CLiSO) framework extending the previously proposed Lightweight edge Slice Orchestration (LeSO) framework. In addition, the framework offers a technology-agnostic and deployment-oriented network slice template. The framework has been thoroughly evaluated via orchestrating OpenAirInterface container network functions on public and private cloud platforms. The experimental results show that the framework has lower resource footprints than existing orchestrators and takes less time to orchestrate network slices

Texto completoNext generation wireless networks, i.e., fifth generation (5G) and beyond (B5G), are expected to be highly heterogeneous, multilayered, with embedded intelligence at both thecore and edge of the network. In such a context, system-level performance evaluation will be very important to formulate relevant insights into tradeoffs that govern such a complex system and then prevent the need for onerous and timeconsuming computer simulations. Over the past decade, stochastic geometry has emerged as a powerful analytical tool to evaluate system-level performance of wireless networks and capture their tendency towards heterogeneity. This dissertation reviews first novel stochastic geometry models and techniques developed during the last decade in modeling and analysis of modern wireless networks. The discussions are refined enough to be accessible for non-specialist readers and help new, intermediate, or advanced readers familiarize quickly with this field of research. Next, we leverage stochastic geometry frameworks to investigate several aspects of 5G and B5G wireless networks and then illustrate its mathematical flexibility and ability to capture the analysis of the rather unconventional scenarios. Also, new perspectives that will breathe new life into the use of stochastic geometry during this crucial decade are discussed. In a nutshell, extensive discussions were held on broader topics such as free space (FSO) optical communications, visible light communications, unmanned aerial vehicle systems, fog radio access architecture (F-RAN) , artificial intelligence and machine learning, and molecular communications
Allouis, Alain. "NOMA-MCM strategies in transmission and reception for advanced vehicular communications in 5G and beyond". Electronic Thesis or Diss., Valenciennes, Université Polytechnique Hauts-de-France, 2024. http://www.theses.fr/2024UPHF0003.
Texto completoThe realm of intelligent transportation hinges upon robust vehicular communication infrastructure, vital for traffic management, road monitoring, Internet of Things (IoT) accessibility, and driver/passenger information. While the conventional IEEE802.11p standard has long dominated this domain, the advent of 5G and its successors marks a paradigm shift.This thesis represents a comprehensive exploration of 5G and beyond technologies specifically tailored to the unique demands of Vehicle-to-Everything (V2X) communication. The primary aim is a meticulous analysis of Non-Orthogonal Multiple Access (NOMA) technology and Multi-Carrier Modulation (MCM) schemes within the context of next-generation V2X applications. Central to this exploration is the pursuit of cross-layer PHY/MAC (Physical Layer/Medium Access Control) design strategies aimed at elevating performance benchmarks.The research journey begins with an introductory overview, delving into the historical context and relevance of V2X communications, accompanied by an examination of the diverse requirements across V2X use case groups. This foundational groundwork combines insights from normative organizations and the latest literature, providing a comprehensive overview of the historical landscape of vehicular communication.Subsequently, the thesis navigates the contemporary landscape, emphasizing the application of 5G enabling technologies to various V2X use cases. It maps the relationship between V2X Use Case Groups and Enabling Technologies while exploring the Hierarchical 5G V2X high-level architecture. This exploration bridges current communication requirements and existing standards with open research directions and impending challenges.The core of the thesis revolves around the exploration of NOMA and MCM schemes' implications within next-generation V2X applications. The culmination of this research manifests in a cross-layer design paradigm focusing on the enhancement of performance and adaptability within cellular vehicle-to-everything (C-V2X) communication systems. By dissecting NOMA mechanisms within the Physical/Medium Access Control (PHY/MAC) layers, this study demonstrates substantial throughput performance improvements compared to conventional Orthogonal Multiple Access (OMA) systems.The outcomes of this thesis aspire to contribute advanced solutions for future autonomous and connected transport systems, with a specific emphasis on the enhancement of physical and medium access layer performance within sophisticated V2X scenarios
