Abstract:
1. A routing method for use in a delay tolerant network (DTN) capable of distributing forwarding data by temporarily storing the forwarding data in an intermediate node even if there is no end-to-end reachability from a source node to a destination node, the routing method comprising: a routing protocol step, executed on a processor, of causing each node of the delay tolerant network to calculate a distribution probability of the each node with respect to the destination node based on a log of end-to-end paths from the each node to the destination node from the past to the present registered in a routing table of the each node; and a DTN forward step of causing the source node to select a next hop node to be used to forward the forwarding data from the source node to the destination node, based on the calculated distribution probability of the each node with respect to the destination node.
