中文摘要: 为了提高延迟容忍网络中数据投递过程节点能耗管理效率、改善数据在网络中的转发效率等，本文引入节点间能耗博弈模型，进而提出了一种基于能耗自选演进机制的延迟容忍网络路由算法（Efficient Routing Mechanism for Delay Tolerant Network based on Energy Consumption Strategy），根据泛洪路由策略设计数据投递机制，数据在网络中转发时，节点依据自身能量剩余状态制定相应的投递操作，对首先将数据投递至目的节点的中间节点予以一个单位的奖励，利用节点策略博弈模型选取合理的数据投递操作，以此改善节点转发数据能量消耗，从而提高数据投递能量管理效率，并提高数据转发效率.仿真验证表明：所提算法与对照算法相比在数据投递率、传输时延、网络开销等性能指标上表现出较好效果.
Abstract: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.
