Full textOrganizing the information that we call personal files such as files in a home directory, web pages found on the Internet, images, emails for later revisiting is currently required by many computer users. Several information retrieval models are proposed to fullfil this requirement. Each model is characterized by the types of personal files, their organization and the searching method used. Traditional file systems let a user organize his files into a directory tree and retrieve them later by browsing the directory tree. Desktop seach tools such as Google Desktop or Beagle automatically index file properties and file content (keywords) to provide the user with file retrieval by querying on file properties or on file content. Semantic file systems propose a searching method that combines querying with browsing to give to the users the advantages of both searching methods. For informations on the Internet, tagging systems are more and more used to facilitate the re-finding of these Internet ressources. Among personal file characteristics (properties, content, context) exploited by the above retrieval models, the working context of the user has been proved to be relevant to help a user to successfully retrieve his personal files. This work proposes a model for personal file retrieval, called « context-based model for personal file retrieval ». Our model allows a user to associate his personal files with a working context using tags. To retrieve a personal file, the user must describe the working context corresponding to each file. The searching method in our model gives to the users the advantages of both searching methods: browsing and querying. We develop our model by improving traditional tagging models. Based on tag relationships and popularities, we organize tags created by a user into a directed acyclic graph (DAGoT). This DAGoT is used as the basic data model to realize our context-based model for personal file retrieval. We use this graph to recognize working contexts associated to personal files, guide a user to reconstruct his working contexts, refine the searching requests, and retrieve personal files by context

Full textWe present in a new method for the conception of evolving and customizable classification systems. We propose an incremental approach for the learning of classification models based on first-order Takagi-Sugeno (TS) fuzzy inference systems. This approach includes, on the one hand, the adaptation of linear consequences of the fuzzy rules using the recursive least-squares method, and, on the other hand, an incremental learning of the antecedent of these rules in order to modify the membership functions according to the evolution of data density in the input space. The proposed method resolves the instability problems in the incremental learning of TS models thanks to a global learning paradigm in which antecedent and consequents are learned in synergy, contrary to the existing approaches where they are learned separately. The performance of our system had been demonstrated on different well-known benchmarks, with a special focus on its capacity of learning new classes

Full textSimulation is a powerful tool to study distributed systems. It allows researchers to evaluate different scenarios in a reproducible manner, which is hardly possible in real experiments. However, the realism of simulations is rarely investigated in the literature, leading to a questionable accuracy of the simulated metrics. In this context, the main aim of our work is to improve the realism of simulations with a focus on file transfer in a large distributed production system (i.e., the EGI federated e-Infrastructure (EGI)). Then, based on the findings obtained from realistic simulations, we can propose reliable recommendations to improve file management in the Virtual Imaging Platform (VIP). In order to realistically reproduce certain behaviors of the real system in simulation, we need to obtain an inside view of it. Therefore, we collect and analyze a set of execution traces of one particular application executed on EGI via VIP. The realism of simulations is investigated with respect to two main aspects in this thesis: the simulator and the platform model. Based on the knowledge obtained from traces, we design and implement a simulator to provide a simulated environment as close as possible to the real execution conditions for file transfers on EGI. A complete description of a realistic platform model is also built by leveraging the information registered in traces. The accuracy of our platform model is evaluated by confronting the simulation results with the ground truth of real transfers. Our proposed model is shown to largely outperform the state-of-the-art model to reproduce the real-life variability of file transfers on EGI. Finally, we cross-evaluate different file replication strategies by simulations using an enhanced state-of-the-art model and our platform model built from traces. Simulation results highlight that the instantiation of the two models leads to different qualitative decisions of replication, even though they reflect a similar hierarchical network topology. Last but not least, we find that selecting sites hosting a large number of executed jobs to replicate files is a reliable recommendation to improve file management of VIP. In addition, adopting our proposed dynamic replication strategy can further reduce the duration of file transfers except for extreme cases (very poorly connected sites) that only our proposed platform model is able to capture

Full textRecently, operators have resorted to femtocell networks in order to enhance indoor coverage, network capacity and quality of service since macro-antennas alone fail to reach these objectives. Nevertheless, they are confronted to many challenges. To successfully deploy such solution, efficient resource allocation algorithms and interference mitigation techniques should be deployed. In this thesis, we address the issue of resources allocation in femtocell networks using OFDMA technology (e. G. , WiMAX, LTE). Specifically, we first propose a hybrid centralized/distributed resource allocation strategy for split spectrum namely Femtocell Cluster-based Resource Allocation (FCRA). Firstly, FCRA builds disjoint femtocell clusters. Then, within a cluster the optimal resource allocation for each femtocell is performed by its clusterhead. Finally, the contingent collisions among different clusters are fixed. To achieve this, we formulate the problem mathematically as Min-Max optimization problem. Then, a co-channel resource allocation algorithm (CO-FCRA) introduces spectrum sharing between femto and macro users. Spectrum sensing approaches are used to detect existing neighboring transmissions in the uplink and estimates resources used in the downlink to allocate resources accordingly. In a second approach, we consider networks with quality of service differentiation among users and propose a new algorithm, namely (Q-FCRA) with both high priority and best effort users. The optimization problem is modified to take into account both user types and allocates resources accordingly. The objective is to maximize the number of accepted high priority users and allocate as much as possible best effort users. As a third contribution, we present a power control algorithm (QP-FCRA), where femto stations allocate both resource blocks and transmission power on the different channels to effectively mitigate interference within the same cluster and increase the spectrum spatial reuse. The transmission power is calculated based on the interference received to satisfy a minimum required SINR threshold. Several existing works have been used for comparison. Different network densities, interference levels, session duration and mobility rates have been considered. Performance evaluation shows the improvement and the outperformance of our algorithms compared to the existing techniques regarding different performance metrics such as the number of accepted and rejected users, the fairness, the throughput satisfaction rate, the spectrum spatial reuse and the convergence and computation time. The scalability of our algorithm compared to the centralized ones is proven as well as the performance compared to the distributed algorithms
