Abstract : Ad-hoc networks are self-organizing networks that can be spontaneously deployed from a set of mobile devices without requiring any pre-existing fixed infrastructure. Managing such dynamic networks is significantly harder and more complex than managing traditional fixed networks. Indeed, the network topology is dynamic with a high rate of change. Moreover, the network is self-maintained by devices that usually operate under many constraints such as limited battery power, restricted bandwidth and low system capacity. All these factors make traditional management schemes inefficient and expensive. This thesis proposes a new management approach for ad-hoc networks and their services capable to take into account their dynamics and their limited resources. We first design a complete information model capable to represent management data for the spatial, temporal and traffic aspects of ad-hoc networks. Thus, the accurate and comprehensive representation of parameters which drive the evolution of these networks is made possible. We then reorganize the management plane based on a probabilistic scheme, with which the management task is limited to a specific subset of nodes in a light-weight and flexible way. Finally, we adapt the management operations to ad-hoc specifics based on analytical methods such as eigenvector centrality and k-means classification techniques. Our contributions are evaluated through different analytical models, through an extensive set of simulations and through the implementation prototype of a monitoring platform.
