The present invention relates to a technique for transmitting a message in a community-based delay tolerant network (DTN) consisting of a plurality of nodes and links connecting the nodes. In every node, a buffer and a priority queue for storing a message are present, and are performed by a computing device. Specifically, when an intermediate node (i) is a termination node (d), a message is transmitted to the termination node (d). When the intermediate node (i) and the termination node (d) pertain to the same community and the centrality of the intermediate node (i) is greater than that of a source node (s), a message is transmitted to the intermediate node (i). When the intermediate node (i) and the termination node (d) pertain to the same community but the centrality of the intermediate node (i) is not greater than the centrality of a source node (s), a message is copied. When the intermediate node (i) and the termination node (d) do not pertain to the same community, the source node (s) and the intermediate node (i) pertain to the same community, and the probability of the intermediate node (i) is greater than that of the source node (s), provided is a protocol for transmitting a message in the DTN through a method for transmitting a message to the intermediate node (i). The present invention is designed to provide an efficient protocol capable of transmitting a message while minimizing costs in a DTN. |
