Texto completoThe evolution of structural health monitoring (SHM) in recent years has witnessed the emergence of independent sensor networks with limited material resources. However, the signals recorded by these sensors for passive imaging can exhibit desynchronizations that make it difficult to locate damage in the inspected structure. Although the peak correlation technique (PCT), based on the symmetry of noise correlation functions, can be applied to correct these offsets, achieving perfect synchronization is challenging in the presence of electronic noise and/or reconstruction of the Green's function. In this manuscript, a study of the behavior of residual errors associated with imperfect resynchronization, as a function of the statistical parameters of noise, is conducted. Then, the degradation of the contrast of defect localization images is quantified as a function of the standard deviation of these resynchronization errors. Subsequently, a process based on the Moore-Penrose pseudo-inversion is developed to minimize these errors and improve the quality of the localization images. This study is then extended to the case of defect localization with anisotropic scattering. Finally, a feasibility study is carried out on a network of wireless communicating sensors

Texto completoThis thesis is motivated by the study of sensors networks. The goal is to compare networks using their conditional independence structures. This structure illustrates the relations between two sensors according to the information recorded by the others sensors in the network. We made the hypothesis that the studied networks are multivariate Gaussian processes. Under this assumption, estimating the conditional independence structure of a process is equivalent to estimate its Gaussian graphical model.First, we propose a new method for Gaussian graphical model estimation : it uses a score proportional to the probability of a graph to represent the conditional independence structure of the studied process and it is initialized by Graphical lasso. To compare our method to existing ones, we developed a procedure to evaluate the performances of Gaussian graphical models estimation methods. One part of this procedure is an algorithm to simulated multivariate Gaussian processes with known conditional independence structure.Then, we conduct a classification over processes thanks to their conditional independence structure estimates. To do so, we introduce a new metric : the symmetrized Kullback-Leibler divergence over normalized cross-profiles of studied processes. We use this approach to find sets of brain regions that are relevant to study comatose patients from functional MRI data

Texto completoPrivacy notion is frequently linked with cyber attack examples by media and scientific researches. In 2012, the hacking of 12 millions Apple user identifiers demonstrates that connected objects represent leaks exploited by hackers to access to user personal data. In this thesis, we will extend the privacy notion to the objects. To do this, we will show that in wireless sensor networks where communications are carried out from machine-to-machine, the knowledge of the static addresses of the devices within the network discloses information allowing deduction about elements of context and environment.Nowadays, the wireless communication standards provide security mechanisms whatever the communication protocols used including the low power ones designed to run on constrained environment. However, the frame header that comprises necessary information for routing and for the proper functioning of the network is always sent in clear text. Collecting and gathering these metadata by eavesdropping is dangerous for the environments and applications based on these networks.The work carried out in this thesis aims to explore how simple passive attacks on meshed networks based on IEEE 802.15.4 used to collect and exploit metadata allow to infer critical information about the network, the environment where the network is deployed and the behavior of users. Two kinds of solutions to hide the node addresses are studied. The first one provides anonymity for the devices. In the second kind of solutions, pseudonyms are used by nodes enabling the capability to audit the traffic within the network.To evaluate the characteristics and the performances of the solutions, a simulator has been used to reproduce the behavior of a meshed wireless sensor network embedding Contiki OS. This simulator allows to compare the performances of MT6D the most promising solution of our state of the art with that of a reference network do not mask the metadata. With this analyze, we can highlight some drawbacks and more especially the control frames overhead needed for the routing. We give the necessary specifications to deploy the most optimal solution for the embedded devices.Thus we propose Ephemeral that allows hiding device addresses provided in the sent frames by using pseudonyms without overhead on the control frames. After deployment in the simulation environment to evaluate expected theoretical performances, Ephemeral has been tested in real environment. The network is made up of twenty IEEE 802.15.4 sensor nodes deployed on a building. The results show that Ephemeral is an efficient low power and bandwidth-saving solution to hide device identifiers used in wireless communications

Texto completoThe electric systems and the associated infrastructures interfere more and more one another and the global vulnerability increases. Due to the complexity and connectivity, a single infrastructure failure could have cascading effects. The transmission system operators guarantee the electric power systems operational security. In order to administrate it as well as possible, system operators use as tools the ‘ancillary services', supplementary functions performed, as a support for their basic services, by the same equipments that produce and transmit the fundamental electricity commodity. In the nowadays deregulation context, new independent power producers demand the connection to the transmission and distribution grid. These new producers are constrained to participate to ancillary services. In order to maintain the grid security and reliability, to allow the commercial transactions correct functioning, system operators are responsible of the ancillary services existence in appropriate quantities and of the power producers control in terms of ancillary services participation ratio. This PhD thesis proposes a power producers' performance control based on parameter estimation starting from disturbances measurements

Texto completoWireless sensor networks are difficult to design because they are highly energy constrained and because each element may have an influence on the lifetime. Ln order to test solutions before being deployed, we propose to build models that can be analyzed. We built Glonemo, a global and precise sensor network mode!. Implemented in ReactiveML, this executable tool can simulate large scale networks while evaluating precisely energy consumption. Ln order to have realistic simulations, an environment model is included. Even if Glonemo semantic is formally-defined, exhaustive analyses are hopeless because of the size of the models. That is why we need abstract models. We propose a global but simplified sensor network model. Using IF toolbox, we compute the worst-case lifetime of this system. At last, we defined a modular abstraction relation for consumption models. Our abstractions are conservatives: properties proved on an abstract model are true on a detailed one
