摘要： 延迟容忍网络(DTN)的节点资源受限，易产生自私行为影响网络性能。针对该问题，提出一种面向DTN的信誉方案，以减小自私行为对网络性能的影响。设计报文转发协议和行为记录机制，检测DTN环境下的自私行为，建立信誉模型，实现对网络节点可信度的评估。实验结果表明，该方案可在存有自私节点的环境中提高网络性能。

Abstract: Due to the constrained resources, Delay Tolerant Network(DTN) nodes hardly resist their selfish behavior. Aiming at this problem, this paper presents a reputation scheme for DTN to minimize the impairment of the selfishness. A protocol of message forwarding and a mechanism of recording are proposed for the detection of selfish behavior. A reputation model is presented to determine the trustworthiness of modes. Experimental results demonstrate the effectiveness of the scheme in the presence of selfish nodes.
