DTN APPARATUS AND METHOD FOR DATA DELIVERY IN DELAY-TOLERANT NETWORKDTN

摘要

A Delay-Tolerant network (DTN) node 12 includes a processor 22 coupled to the memory 32 and adapted to perform a data transfer process for the DTN 1. The processor 22 receives 201 a plurality of bundles # 1 to #N to be transmitted to the same destination node 14 on the DTN 1. Each of the plurality of bundles (# 3 to #N) includes any one of a plurality of data segments obtained by dividing the data of the content. Depending on the communication state of the DTN 1, the processor 22 does not transmit some of the bundles (# 5 to #N) of the plurality of bundles (# 3 to #N) to any other node, # 5 to #N) is compressed (203). In this way, for example, the amount of data delivered within the DTN can be adjusted according to the local communication state of the DTN.
