Abstract:  A large number of messages will be dropped when buffer space of network node is limited in delay tolerant networks. A reliable routing algorithm RPROPHET based on probabilistic delivery is proposed. According to the history information of messages replacement in nodes buffer. the reliablity of nodes is evaluated by the routing algorithm. In order to deliver messages to the destination node, the messages are transferred among the reliable nodes. Simulation results show that the proposed algorithm can alleviate ineffective delivery. It can increase the delivery ratio and reduce communication overhead.
