摘要：Delay Tolerant Networks have been (DTN) have been developed to support the irregular connectivity oftenseparate networks. The main routing problem in this type of network is embarrassed by time that isextremely long, since connections are intermittent and opportunistic. Routing protocols must take intoaccount the maximum constraint encountered in this type of environment , use effective strategiesregarding the choice of relay nodes and buffer management nodes to improve the delivery of messages andthe time of their delivery . This article proposes a new strategy that optimizes the routing Spray and wait.The proposed method uses the information contained in the messages delivered mostly paths traversed bythe messages before arriving at their destination and the time when nodes have receive these messages.Simulation results show that the proposed strategy can increase the probability of delivery and minimizingoverhead unlike FIFO technology used with the default routing ' sprat and wait
