Abstract：In order to solve the routing problem of delay tolerant networks in short contact time，a routing scheme for delay tolerant network in short contact duration time network environment is proposed.The proposed scheme firstly calculates the one-hop delivery probability and two-hop delivery probability by using the network information such as the contact duration time，the inter-contact time and the message time-to-live，and then the relay nodes is selected from the current contact nodes and the past contact nodes according to the obtained delivery probability.The simulation results show that the proposed scheme can improve the the message delivery rate and shorten the average delay while reducing the routing cost by comparing with other classical routing scheme of delay tolerant networks.
