A Disruption Tolerant Network (DTN) is characterized by scenarios where end-to-end connectivity is rarely available. Hence, in such networks, the use of existing ad hoc routing protocols may result on poor performance, since they rely on the existence of an end-to-end path between the source and destination nodes. This paper proposes a DTN routing strategy called DRAIN. Differently from other proposals based on Epidemic routing, DRAIN considers realistic scenarios where nodes' buffer capacitydoi:10.14209/jcis.2008.2 fatcat:llxffoa5wjh3thsxdqlh6zs5my
