Integrated Fuzzy Solution for Network Selection using MIH in Heterogeneous Environment

2013

ISSN: 1942-2644; International audience; Seamless handover between networks in heterogeneous environment is essential to guarantee end-to- end QoS for mobile users. A key requirement is the ability to select seamlessly the next best network. Currently, the implementation of the selection algorithm of the IEEE 802.21 standard by National Institute of Standards and Technology considers only the signal strength as a parameter to select the best destination network. In this paper, we improve the implementation of the existing selection algorithm by proposing an integrated solution to select the best destination network. Our proposed solution consists of proposing a Multi Criteria Selection Algo…

IP-Based Mobility Management and Handover Latency Measurement in heterogeneous environments

2017

International audience; One serious concern in the ubiquitous networks is the seamless vertical handover management between different wireless technologies. To meet this challenge, many standardization organizations proposed different protocols at different layers of the protocol stack. The Internet Engineering Task Force (IETF) has different groups working on mobility at IP level in order to enhance mobile IPv4 and mobile IPv6 with different variants: HMIPv6 (Hierarchical Mobile IPv6), FMIPv6 (Fast Mobile IPv6) and PMIPv6 (Proxy Mobile IPv6) for seamless handover. Moreover, the IEEE 802.21 standard provides another framework for seamless handover. The 3GPP standard provides the Access Netw…

HQMR: Hybrid QoS based Routing Protocol for Wireless Mesh Environment

2015

International audience; Wireless Mesh Networks (WMNs) have been attracting more and more interest from both academic and industrial environments for their seamless broadband connectivity to Internet networks. Besides, providing QoS guarantees for real-time and streaming applications such as Voice over IP (VoIP) and Video on Demand (VoD) is a challenging issue in such environment. Thus, we propose a novel QoS based routing protocol for wireless mesh infrastructure, called Hybrid QoS Mesh Routing (HQMR). Moreover, a clustering algorithm is developed to enhance scalability issues within the mesh infrastructure. HQMR is composed of two routing sub-protocols: a reactive routing protocol for intr…

Adéquation Algorithme architecture : Aspects logiciels, matériels et cognitifs

2008

Les travaux présentés dans le cadre de cette Habilitation à Diriger des Recherches s'inscrivent principalement dans la problématique dite d'" Adéquation Algorithme Architecture ". Ils ont pour objectif commun la mise en œuvre de systèmes matériels et logiciels dédiés à la vision artificielle à fortes contraintes temporelles. Ils se focalisent sur différents aspects cruciaux tels que l'acquisition d'images par des capteurs dédiés, le développement et la programmation d'architectures optimisées de traitement des images et l'implantation d'algorithmes de traitement du signal et d'images en temps réel sur ces architectures.

Projet CHIROLUM. Comment limiter les impacts écologiques de l’éclairage artificiel nocturne le long des ILTe ? Caractérisation de l’influence des par…

2021

Ce rapport expose les résultats du projet Chirolum ayant pour objectif d'identifier des pistes de réduction des impacts écologiques de l'éclairage artificiel le long des infrastructures de transport. En prenant l'exemple de sites d'études le long de lisières forestières aux Pays-Bas et le long du Canal du Midi à Toulouse, les résultats montrent que la lumière perturbe fortement l'usage de ces continuités écologiques et infrastructures de transport par les chauves-souris, engendrant des modifications dans le comportement de vol et potentiellement des coûts énergétiques supplémentaires, ainsi qu'une diminution de la connectivité fonctionnelle pour ces espèces potentiellement préjudiciables à …

2019

International audience; Des Réserves internationales de ciel étoilé à la "Trame noire", la mise en protection de la ressource obscurité revêt des déclinaisons plurielles (socioculturelles, écologiques et sanitaires) et s’incarne dans des démarches dont les méthodologies sont parfois encore peu éprouvées. Elle n’en est pas moins un sujet bénéficiant d’un réel effet de mode. Qu’on la qualifie par la perte de patrimoine, la dégradation d’habitats, les effets perturbateurs voire destructeurs sur les espèces, ou bien la construction potentielle de ressources pour l’action collective locale, l’appropriation de cette thématique de protection par les réseaux d’aires protégées est pl…
