During the first three years, COMMUNITY explored solutions to enable efficient delivery mechanisms for disruption-prone and heterogeneous networks (i.e., challenged networks). This resulted in the MeDeHa framework along with the Henna naming scheme, which allow communication in infrastructure and infrastructureless networks with varying degrees of connectivity. The team also proposed efficient routing strategies adapted to environments with episodic connectivity that take into account the utility of nodes to relay messages. The various solutions have been evaluated using both simulations and real experimentations in testbeds located at Inria and UC Santa Cruz. These solutions have demonstrated good performance in challenged networks. However, the ossification of the Internet prevents the deployment of such solutions in large scale. Following, in 2012, the team pursued its collaboration along two research directions: (i) the design of innovative information-centric communication mechanisms adapted to challenged networks; and (ii) the exploration of the SDN – Software-Defined Network – paradigm to facilitate the implementation and large-scale deployment of new network architectures, to offer innovative services such as capacity sharing.
