In a future, existing wireless access technologies such as WiFi (Wireless Fidelity), WiMAX (Worldwide Interoperability for Microwave Access) and UMTS (Universal Mobile Telecommunication System) will coexist on daily basis. Nevertheless, this daily coexistence does not imply that they will be able to fully interoperate. Thus, my research work focuses on a specific roaming scenario which is formed by heterogeneous wireless access networks managed by different operators. Our main objective is to provide a seamless (for the mobile user) roaming architecture to enable network interoperability under a heterogeneous multi-operator wireless environment, all this without major changes in current wireless architectures. In this regard, we also aim at reducing the roaming signaling exchange caused by the authentication and authorization mechanisms in the network registration and session initiation process while providing robust network security. The results obtained through computer simulation indicated that the use of our approach reduces significantly the network registration and session initiation delay, hence outperforming the traditional Roaming-SIP method. We also confirmed that the wireless delay introduced by the VN increases considerably when increasing the traffic congestion level in the Visiting Networks. Thus, from the simulations results we can state that by reducing the signaling message exchange, and maintaining acceptable congestion levels in the wireless network, hence reducing the wireless transmission delay, we can improved the overall de-lay in both network registration and session initiaition process

The Software Defined Radio (SDR) techniques aim at offering an access to a broad choice of radio communications standards on a flexible hardware (HW) architecture which is necessary in order to answer the diversity of the processing to carry out. The digital communications techniques involve heterogeneous resources needs. The reconfigurability of a heterogeneous HW platform is thus a key features to a successful appearance of SDR systems. The reconfigurability of a SDR system must meet the needs for adaptation of the processing functions to answer the requirements of the contexts switching. Our work is based on the analysis of the baseband processing in the transmitting chains of the 3 standards UMTS, GSM and 802. 11g. We propose an analysis of factorization of the multistandard baseband processing in order to reduce the number of contexts to be managed and we determine the needs for flexibility of SDR applications. In this context, the configuration management of HW platforms clearly appears as the key feature of a SDR system. We propose a Hierarchical and Distributed Configuration Management (“HDCM”) approach in order to meet the needs of managing various types of flexibility of dataflow oriented applications mapped on heterogeneous HW. The implementation of applications on reconfigurable heterogeneous platforms and in particular on configurable logic devices, requires the uses of new design methodologies in order to extract the potential reconfigurability of these reconfigurables devices. We bring in this work various design methodologies that aim at designing partially and dynamically reconfigurable systems on chip and on FPGA

Recently, the giants of the Internet are adopting every day more and more the benefits of virtualization within the data center. Each virtualized application and its operating system can run simultaneously from one physical device. This technology reduces significantly power consumption, energy consumption, as well as operational cost. Furthermore, not long ago, this promising solution is studied by the research communities to be extended for network virtualization deployment. In traditional network physical device like routers and/or switches are responsible to transfer the information from one point to another, following the instructions previously programmed by a network administrator. At this time, the physical networking devices can be virtualized, providing an intelligent abstraction via virtual network software that makes easy to deploy and manage network resources. The search giant Google has deployed SDN to experiment with the inter-connection between their data center around the world [1].With the exponential growth of devices connected to the Internet, security network is one of the hardest challenge for network managers. Maintaining and securing such large scale and heterogeneous network is a challenging task. In this context, the new networking paradigm, the Software Defined Networking (SDN), introduces many opportunities and provides the potential to overcome those challenges. In our approach, we first propose a new SDN based architecture for networking with or without infrastructure, that we call an SDN domain. This domain includes wired network, wireless network and Ad-Hoc networks. Next, a second architecture includes sensor networks in an SDN-based network and in a domain. Third, interconnecting multiple domains and we describe how we can enhance the security of each domain and how to distribute the security rules in order not to compromise the security of one domain. Finally, we present a new secure and distributed architecture for ad-hoc networks and IoT (Internet of Things)
Le, Guellaut Christophe. "Prototypage d’un système MIMO-MC-CDMA sur plateforme hétérogène." Rennes, INSA, 2009. https://tel.archives-ouvertes.fr/tel-00419176.
This thesis deals with the implementation of communication systems into a SUNDANCE heterogeneous latform, composed of DSPs and FPGAs in the context of convergence of local area networks and cellular networks. The hysical layer of our system is based on MIMO-MC-CDMA with two transmit antennas and two receive antennas. IMO-MCCDMA combines spectrum spreading, OFDM, and Alamouti space-time coding, so that it benefits from frequency diversity and spatial diversity. Our work leads to the implementation of the baseband transmitter, including start of frame detection and channel estimation. Studies concerning the radiofrequency stages are presented. Our baseband implementation raises the question of the hardware requirements for next generation wireless networks. To this end, we have proposed a very efficient transmitting scheme for MIMO-OFDM systems. Besides, a new application has been designed to promote our platform

This thesis focuses on multi scale simulations heterogeneous catalysis reactions of polyols on platinum (111) in aqueous phase. This work is about lignocellulosic biomass valorisation. The reaction networks raising from these materials are extremely large and complex. Also, the properties of the molecules forming this biomass make aqueous conditions mandatory. Ab initio methods as we know them forbids us to treat entire networks at the finest calculation level, the computational cost would be way beyond feasibility. Changing the simulation scale can tackle this problem. Thus, we developed a group additivity model assessing for thermochemical properties of polyols at a platinum (111) surface under aqueous conditions, with a topology as the only input. This model was built upon a density functional theory set. Kinetics of reactions was also covered, and the difference in terms of impact was investigated between implicit and explicit micro solvation models, in order to predict reaction barriers. The two models might be used together in order to feed a micro kinetic simulation, allowing a drastic decrease of reaction networks complexity. Finally, the influence on reactivity and selectivity, of hydroxyl groups on butanediol isomers was investigated
