Routing strategy for minimizing the packet loss in disruptive tolerant networks

In this paper, it is discussed how to do routing in disruptive tolerant networks (DTN) in order to minimize the packet loss. In DTN there is no guarantee of path existence between the source and the destination. For such networks, the usual networking protocols do not work properly and cannot deliver the packets between nodes in the network. However there are cases where the connectivity between 2 nodes doesn´t exist at any given time but communication is still possible. In this paper, we propose a routing heurestic, for minimizing the packet loss in DTN, where the nodes have finite buffers.
