%X In delay tolerant network (DTN), most of the existing routing algorithms only consider the local resource status of the network to select the relay nodes, which can not make the global network performance optimal or sub-optimal. According to this problem, an optimal control information generation method (OCIGM) for DTN routing was proposed. The method can evaluate the global network state and generate the optimized control information for the DTN routing. The mobile terminal adjusts the routing policy by limiting the number of replicas of the message according to the optimization control information. Simulations show that the spray and wait (SAW) routing algorithm reduces the network overhead and packet loss ratio under the OCIGM optimal control information generation method. Meanwhile, the delivery ratio of message is improved.
