Texto completo da fonteNowadays, collaborative work took a very important place in many fields and particularly in the medicaltelediagnosis field. The consistency of shared data is a key issue in this type of applications. Moreover, itis essential to use a consensus algorithm to ensure data consistency in collaborative platforms. We presenthere our new consensus algorithm FLC that helps to ensure data consistency in asynchronous collaborativedistributed systems. Our algorithm is fault tolerant and aims to improve the performance of consensus ingeneral and particularly in the case of process crashes. The new algorithm uses the leader oracle tocircumvent the impossibility result of the FLP theorem. It is decentralized and considers the crash-stop failuremodel. The FLC algorithm is based on two main ideas. The first is to perform, at the beginning of eachround, a simple election phase guaranteeing the existence of only one leader per round. The second is totake advantage of system stability and more particularly of the fact that the leader does not crash betweentwo consecutive consensus runs. The performance of our algorithm was analyzed and compared to the mostknown algorithms in the domain. The results obtained by simulation, using the Neko platform, demonstratedthat our algorithm gave the best performance when using a multicast network in the best case scenario and insituations where the algorithm undergoes one or more crashes of coordinators/leaders processes

Texto completo da fonteIn recent years, the emergence of new technologies such as miniaturization of components, wireless communication devices, increased storage size and computing capabilities have allowed the design of increasingly complex cooperative multi-agent systems. One of the main research axes in this topic concerns the formation control of fleets of autonomous vehicles. Many applications and missions, civilian and military, such as exploration, surveillance, and maintenance, were developed and carried out in various environments. During the execution of these tasks, the vehicles must interact with their environment and among themselves to coordinate. The available communication tools are often limited in scope. The preservation of the connection within the group then becomes one of the objectives to be satisfied in order to carry out the task successfully. One of the possibilities to guarantee this constraint is the training displacement, which makes it possible to preserve the distances and the geometrical structure of the group. However, it is necessary to have tools and methods for analyzing and controlling these types of systems in order to make the most of their potential. This thesis is part of this research direction by presenting a synthesis and analysis of multi-agent dynamical systems and more particularly the formation control of autonomous vehicles. The control laws developed in the literature for formation control allow to carry out a large number of missions with a high level of performance. However, if a fault/failure occurs in the training, these control laws can be very limited, resulting in unstable system behavior. The development of fault tolerant controls becomes paramount to maintaining control performance in the presence of faults. This problem will be dealt with in more detail in this thesis and will concern the development and design of Fault tolerant controls devolved to a fleet of autonomous vehicles according to different configuration/structuring

Texto completo da fonteThe multiplication of information source and the development of news technologies generates complex databases, often characterized by relatively high number of variables compared to individuals. In particular, in the environmental studies on the indoor air quality, the information's collection is done according to several thematic, yielding column partitioned or multi-block data set. However, in case of high dimensional data, classical clustering algorithms are not efficient to find clusters which may exist in subspaces of the original space. The goal of this work is to develop clustering algorithms adapted to high dimensional data sets with multi-block structure. The first part of the work shows the state of art on clustering methods. In the second part, three new methods of clustering: the subspace clustering method 2S-SOM (Soft Subspace-Self Organizing Map)is based on a modified cost function of the Self Organizing Maps method across a double system of weights on the blocks and the variables. Then we propose two approaches to find the consensus of self-organized maps CSOM (Consensus SOM) and Rv-CSOM based on weights determined from initial partitions. The last part presents an application of these methods on the OQAI data to determine a typology of dwellings relatively to the following topics: indoor air quality, dwellings structure, household characteristics and habits of the inhabitants

Texto completo da fonteBlockchain is a technology that maintains a single record of information in a decentralized and distributed manner while ensuring data security. This technology, which is behind the most popular cryptocurrency, Bitcoin, is changing the way we think about information records in distributed systems. Indeed, the cryptographic feature set and the distributed nature of the technology make blockchain one of the most secure tools available today for maintaining a record of information. The first applications to have adopted this technology are in the field of finance, where it is now possible to carry out transactions directly between users without going through a central authority. However, other fields have also shown interest in this technology, such as medicine, for the secure sharing of medical records; art and music, for the tracking of copyrights and royalties; governance, for secure voting, IoT, etc. However, to benefit from such technology it is necessary to count with high reliability and connectivity, as provided by the Internet. In mesh and mobile ad hoc networks, it is often necessary to deploy its own infrastructure and services where the infrastructure of operators are not available due to the geography of the site or to an exceptional situation as is the case of natural disasters, war zones or monitoring of protected areas to achieve specific missions. The dynamism of these networks makes it difficult to use a blockchain to maintain a record of information. Indeed, the mobility of nodes can cause partitions in the network that may or may not be desired; nodes can appear and disappear, partitions can split or reunite depending on the mobility of the nodes. This poses a problem for a traditional blockchain, as partitions in the network lead to forks (competing chains) that are often resolved by choosing the longest chain and ignoring other competing chains. For the use cases of mesh and mobile ad hoc networks that we seek to solve, the concurrent chains constructed by the effect of network partitions can be considered as legitimate chains carrying information related to a given network partition. It is therefore important to include these chains in the information register. In this thesis manuscript, we propose the Blockgraph, a blockchain-like technology capable of dealing with network partitions for mobile mesh and ad hoc networks. The Blockgraph, takes the form of a direct acyclic graph based on node mobility and inherits all the security properties of the blockchain. In addition, we propose C4M, a RAFT-based consensus algorithm that has been adapted to work with the Blockgraph and is also tolerant to network partitions. To validate our solutions, we first implemented the Blockgraph and C4M in the discrete event simulator, NS-3. We performed a first performance study of each system, then we implemented the Blockgraph in real proof-of-concept mesh routers to validate the effectiveness of our solution. Finally, we performed a performance study and presented our conclusions

Texto completo da fonteIn this thesis, we address the problem of control of multi-agent systems connected over realistic models of communication systems. We mainly focus on systems of connected and automated vehicles (CAVs) that communicate through a 5G communication system, which allows two types of communication: direct communication between nodes, known as Vehicle-to-Vehicle (V2V) communications, and communication through the network infrastructure, which is the traditional way of communication in cellular networks.The thesis discusses three problems: first, we analyze the stability and convergence properties of the consensus algorithm of first-order integrator agents using a time-division multiple access (TDMA) scheme to share the network resources of a broadcast shared communication channel. Exponential stability of the considered system is proved, and an explicit bound depending on the communication system parameters is provided to estimate the convergence rate. Second, we treat the problem of formation control of a float of connected vehicles in a 5G communication context. We propose a resource allocation algorithm to select the transmitting users to achieve the desired formation while satisfying the constraints imposed by the communication system. Finally, we study the stability properties of Kalman filters for hybrid systems, i.e., systems with continuous-time dynamics observed through discrete-time measurements. Input-to-state stability (ISS) is proved for such systems relying on an appropriate Lyapunov function. This result can be considered as a first step in the robustness analysis of the overall system since it allows to treat the effects of communication errors on the controlled system stability
