中文摘要: 详细研究了延迟容忍网络(DTN)的一种确定性路由算法—ED(Earliest-Delivery)，分析了其计算延时开销函数，并在此基础上充分考虑了传播延时、节点之间链路的连接规律，引入链路连接状态表来选取路由决策时刻，优化延时开销的计算。实验结果表明，改进后的ED算法可以有效地降低延时，提高路由成功率。
Abstract:This paper focuses on one of DTN’s deterministic routing algorithms—ED (Earliest-Delivery) and makes an analysis of its calculation of the delay cost function. To select the accurate time of routing decision-making and optimize the calculation of delay cost, a link connection state table is employed. On this basis, the transmission delay and rules of node-link connection are taken into account. Experimental results show that the improved ED can effectively reduce the delay and improve routing success rate.
