The invention discloses a delay tolerant and disruption tolerant network (DTN) opportunity prediction routing method based on a timetable. On the base of the research on the routing mechanism of the existing delay tolerant and disruption tolerant network, an aggregated-unfolded mobile terminal, an opportunity prediction DTN routing algorithm based on a timetable and a cache management strategy are designed in view of the characteristics of special battlefield environments and mobile motorcades, physical positions of nodes and a meeting probability of the nodes can be predicted according to the moving timetables of the mobile nodes, then an optimized information forwarding decision is made, so that smooth network communication can be kept on the condition of high delay and frequent link interruption in the battlefield environments, the information transmission reliability and the data throughput are improved, and the delivery delay is shortened, therefore the survivability of a DTN communication network in the battlefield environments is enhanced.
