Adapnet : Stratégies adaptatives pour la gestion de données distribuées sur un réseau P2P

Abstract : In the last few years, the amount of digital information produced has exponentially increased. This raises problems regarding the storage, the access and the availability of this data. Software and hardware architectures based on the peer-to-peer (P2P) paradigm seem to satisfy the needs of data storage but cannot handle efficiently both data accessibility and availability. We present in this thesis various contributions on P2P architectures for managing large volumes of information. We propose various strategies that operate on dedicated virtual topologies that can be maintained at low cost. More precisely, these topologies scale well because the cost for node arrival and node departure is on average constant, whatever the size of the network. We analyze the main paradigms of information sharing on a P2P network, considering successively the problem of access to typed information (semi-structured) and the general case that completely separates the nature of the queries and data location. We propose a routing strategy using structure and content of semi-structured information. We also propose strategies that efficiently explore the network when there is no assumption on the nature of data or queries. In order to manage a quality of service (which is expressed in terms of speed and reliability), we also investigate the problem of information availability, more precisely we replicate data stored in the network. We propose a novel approach exploiting an estimation of local density of data replica.
