摘　　要：针对容延网络延迟较大、数据传输杂乱无序、网络传输吞吐量较低和拥塞程度较大的问题,提出一种时延可容忍数据传输效率实时优化的方法。方法主要是由两部分构成,一部分是基于卡尔曼滤波对容延网络进行时延估计并修正估计存在的误差,另一部分是针对容延网络吞吐性能的分析和对网络拥塞的控制。所提方法可以通过上述两个过程实现对容延网络数据传输效率的优化,仿真证明,所提方法可以有效地控制网络拥塞程度,提高容延网络的吞吐性能,并且对数据包中数据杂乱无序的问题加以修正,实现了对时延可容忍数据传输效率的实时优化。This paper puts forward a method to optimize delay-tolerant data transmission efficiency in real time. The method is mainly composed of two parts. One part is the time-delay estimation for delay-tolerant network based on Kalman filter and the correction of estimation error. The other part is the analysis for the throughput performance of delay-tolerant network and the control of network congestion. Based on these two processes, the proposed method can optimize the transmission efficiency of data in delay-tolerant network. Simulation proves that the proposed method can effectively control the network congestion and improve the throughput performance of the delay-tolerance network. Meanwhile, the problem of data disorder in data packet is corrected and the real-time optimization of delay-tolerable data transmission efficiency is achieved.
