Abstract : This thesis deals with optimization problems in telecommunication networks. Our first goal consist in identifying the specific problems in optical and satellite networks and to present our contributions for optimizing the network resources. The second goal consist in presenting the developed softwares for the design and optimizations of networks.

The first part begins with the presentation of WDM networks. We introduce the models for optical and satellites networks and we propose new algorithmic methods for optimizing resources allocation in these networks. We deals with different problems, routing, grooming and survivability of WDM networks in the three following chapters. Then, we focus on a specific algorithm for allocating frequencies in a satellite network. For each issue, we present our experiments using real network instances.

The second part of this thesis introduces the software developments that have been achieved. The first chapter presents the Porto software which deals with solving routing, grooming and survivability problems in optical networks that uses three hierarchical levels of switching. In the second chapter, we detail the Mascopt software, a library dedicated to graphs and networks optimization which was used for experiments of the first part.
