Plate forme de communication pour les applications à mission critique

This thesis was developed in the context of wireless multi-hop networks. Those networks work by packet forwarding over wireless links (also called hops). Due to the very high dynamics of the environment, self-configuration approaches are used within the network protocols. In those approaches, the parameters of applications and protocols are automatically adjusted whenever a change in the environment occurs. Thus, in this thesis we propose a new approach for the sharing of self-configuration and cross-layering information, as well as two self-configuration algorithms. The first algorithm improves routing on wireless links having a dynamic data rate and transmission power. We present an analytical model to support the results of our routing extensions. The second algorithm that we propose uses control theory and fuzzy logic to adapt the query mechanism of a peer-to-peer file sharing application according to the load experienced on the network.
