MANET protocols typically handle fairly stable and fully connected networks whereas DTN protocols address the sparse intermittently connected ones. But many intermediate situations may occur because of high mobility or radio link instability. In such cases where the network splits frequently into evolving connected groups none of the conventional routing paradigms (DTN or MANET ) are fully satisfactory. This talk will present HYMAD , a Hybrid MANET -DTN routing protocol which uses MANET routing within disjoint groups of nodes while using DTN routing between these groups. The strength of HYMAD lies in its ability to adapt to the changing connectivity patterns of the network. We evaluate the scheme on real life traces of a roller blade tour in Paris which exhibit this highly dynamic connectivity.
