中文摘要：

水花并且等待协议是在延期喷洒协议的经典拷贝有限容忍的网络，在哪个，二进制水花模式能为异构的延期被改进容忍的网络。在这篇文章，节点活动的一个新概念被定义在整个网络在消息传播的方面称节点的重要性。一朵新水花并且与节点活动等待协议被建议在异构的延期改进表演容忍的网络。在喷洒的协议的变化下面使用的一个数学模型也被建议分析协议的期望的延期。模拟证明有节点活动的水花标志比例是最佳的，新协议比另外的相关协议性能更好。因此，这个协议有高效率和好可伸缩性。

英文摘要：

The spray and wait protocol is a classic copy-limited spraying protocol in delay tolerant networks, in which, the binary spray mode can be improved for heterogeneous delay tolerant networks. In this article, a new conception of node activity was defined to weigh the importance of nodes in aspect of message dissemination in the whole network. A new spray and wait protocol with node activity was proposed to improve the performance in heterogeneous delay tolerant networks. A mathematical model used under varieties of the spraying protocols was also proposed to analyze the expected delay of the protocol. Simulations show that the spray token proportion with node activity is optimal and the new protocol is of better performance than other related protocols. Therefore, this protocol has high efficiency and good scalability.
