Abstract
A routing protocol unit () of each node () in a delay tolerant network calculates the probability of distribution to the destination node based on the log of end-to-end paths to the destination node from the past to the present registered in a routing table (). A DTN forward unit () of a source node determines a next hop node to be used to forward forwarding data, based on the calculated distribution probability of each node with respect to the destination node.
