[more ▼] Differential Evolution (DE) algorithms are efficient Evolutionary Algorithms (EAs) for the continuous optimization domain. There exist a large number of DE variants in the literature. In this paper, we analyze the effect of adding a cellular structure to the population of some of the most outstanding existing ones. The original algorithms will be compared versus their equivalent versions with cellular population both in terms of accuracy and convergence speed. As a result, we conclude that the cellular versions of the algorithms perform, in general, better than the equivalent state-of-the-art ones in the two considered issues.

[more ▼] In this work we focus on defining how dynamism can be modeled in the context of multi-objective optimization. Based on this, we construct a component oriented classification for dynamic multi-objective optimization problems. For each category we provide synthetic examples that depict in a more explicit way the defined model. We do this either by positioning existing synthetic benchmarks with respect to the proposed classification or through new problem formulations. In addition, an online dynamic MNK-landscape formulation is introduced together with a new comparative metric for the online dynamic multi-objective context.

[more ▼] La sécurité des Clouds est un aspect essentiel qui n'est pas forcément abordé selon le point de vue de l'utilisateur. En particulier, sur une plate-forme de type IaaS, il est actuellement impossible pour un utilisateur de certifier de manière fiable et sécurisée que l'environnement qu'il a déployé (typiquement sous forme d'une machine virtuelle) est toujours dans un état qu'il juge intègre et opérationnel. Cet article s'attelle à cette tâche en proposant CertiCloud, une plate-forme Cloud de type IaaS qui exploite les concepts développés dans le cadre du TCG mais aussi les éléments matériels que sont les TPM pour offrir à l'utilisateur un environnement sécurisé et sécurisant. Ces deux aspects sont garantis par les deux protocoles TCRR et VerifMyVM qui sont à la base de CertiCloud. Quand le premier permet de certifier l'intégrité d'une machine distante et d'échanger une clef de chiffrement symétrique, le second permet à l'utilisateur de s'assurer dynamiquement et à la demande de l'intégrité de sa machine virtuelle exécutée sur les ressources de \CertiC. Ces deux protocoles étant les briques de base de notre plate-forme, une attention toute particulière a été apportée à leurs élaborations. A cet effet, ils ont été validés avec succès par AVISPA et Scyther, deux outils de référence dans le domaine de la vérification automatique des protocoles de sécurité (cette analyse est présentée dans cet article). Ensuite, la plate-forme CertiCloud est détaillée: outre les protocoles TCRR et VerifMyVM, elle propose le stockage sécurisé des environnements utilisateurs et leurs exécutions à travers un framework de virtualisation reprenant l'hyperviseur Xen. Quand les ressources physiques sont certifiées par TCRR, l'utilisateur peut utiliser à la demande le protocole VerifMyVM pour s'assurer de l'intégrité de son environnement déployé. Un prototype de CertiCloud a été réalisé et nous présentons les premiers résultats expérimentaux qui démontrent de la faisabilité et du faible surcoût de notre approche sur des scénarios classiquement rencontrés sur les infrastructures Cloud de type IaaS.

[more ▼] In this article, we consider a realistic vehicular mobility model, VehILux, and use a sensitivity analysis method to quantitatively study the influence and interdependencies of its parameters. The analysis reveals several properties in the set of parameters. Some are identified as irrelevant to the output while some have stronger impact than expected. This analysis is proposed as a preliminary step to the mobility model optimization, as it permits to significantly reduce the parameters search space.

[more ▼] This paper proposes VehILux, a new vehicular mobility model based on real traffic counting data. It relies on two freely available sources of real information for the country of Luxembourg. The first source is traffic data collected by counting devices located on the Luxembourgian road network, while the second is geographical information about different types of areas: residential, industrial, commercial and other services. VehILux models vehicles commuting around the city of Luxembourg by considering two types of traffic, outer traffic with vehicles entering in the defined geographical area and inner traffic starting from residential zones located inside the geographical area. One part of the collected traffic data is used as input traffic, while another part is used to control the produced traffic and to fine-tune the model. VehILux is coupled with the microscopic road traffic simulator SUMO to produce realistic vehicular traces. [less ▲] Detailed reference viewed: 189 (8 UL) |
