Potacco [Texte imprimé] : noeud polymorphique transparent pour l'adaptation de contenu adapté au contexte

Abstract : With the evolution of fixed and mobile networks, the increasing number of diversified devices, it is now possible to access any type of services, from any type of devices, being connected to any type of networks. By adding the wish of users to receive personalized contents, adapting content has become a major problem. To help to reach this goal, this thesis defines an intermediate flexible node, allowing dynamic adaptation of any type of content depending on the context of the users. This study resulted in the definition of a node architecture, called Potacco (for noeud POlymorphique Transparent pour l'Adaptation de Contenu adapté au COntexte, in French or Transparent Polymorphic node for content adaptation to the context in English) and its implementation and validation. This node: * collects and provides current context information to enable application modules to make adaptation based on such values * manages/coordinates the application modules and the context collectors (e.g. context sensors) * enables the secured deployment of code in the node (the supplier code, but also the target node are authenticated) * may be transparent to the applications and may process data without no mean for the endpoints to detect it. Two demonstrators have been implemented as a proof of concept of this generic node being located in a physical network: as a wired/wireless gateway performing media content adaptation and as a node in an ADSL network inserting transparently the users' context. Then, the use of that node in "overlay" networks has been the subject of a new proof of concept. Two cases were studied: the first one for the provisioning of services adapted to the user's context in a service specific overlay network service, where a case of a personalized IPTV service is presented, and the second one related to the content adaptation of multimedia stream broadcasted on a P2P network where the Potacco node itself is a member of the P2P network. Validation by simulation and real experiments, permitted to evaluate these solutions.
