In order to improve the efficiency of node energy consumption management and enhance the forwarding efficiency of data during the data delivery process in the delay tolerant network, a delay tolerant network routing algorithm based on energy consumption demand evolution mechanism is proposed after introducing the node energy consumption game model. The data delivery mechanism is designed according to flood routing strategy, and the node can develop the corresponding delivery operation according to its own energy surplus when the data is sent to the network, giving a unit of the reward to the middle node for firstly delivering the data to the destination node. Then a reasonable data delivery operation is selected by node strategy game model to improve the energy consumption of nodes, promoting both of the data delivery energy management efficiency and data transmission efficiency. Simulation results show that this algorithm has higher data delivery ratio and lower transmission delay than the contrast algorithm.
