Abstract : The number of devices that are likely to get connected to the Internet (e.g., smartphones, sensors), and the amount of data produced by people using these devices grow continuously, especially in cellular networks. Latest developments performed on the physical layer to increase the networks' bandwidth might be insufficient in the future, because of the emergence of the Internet of things. Therefore, it seems to be interesting to study new or complementary network architectures. Intermittently-Connected Hybrid Networks (ICHN), which are composed both of an infrastructure part and of parts formed by mobile device communicating using ad hoc mode, are examples of those architectures that deserve to be studied. In this thesis, we study benefits that peer-to-peer mechanisms and opportunistic networking techniques could bring to ICHN. We propose a decentralized unstructured peer-to-peer overlay architecture that supports communications between devices in wide ICHNs. A prototype named Nephila has been developed to evaluate this approach in simulation.
