中文摘要：

DTN是从自组织无线网络中抽象出来的网络模型．它不要求网络的全连通．因此更适合实际自组网的需求。大部分DTN传输协议研究的是如何把数据高效、无区分地传给汇聚点。本文提出的基于合并的DTN订阅查询传输协议（如SMR），充分利用DTN节点自身的处理能力，能够在有限的时间内利用节点间的每一次相遇机会尽可能多且有效地传输有用信息。实验结果显示．随着传输时间的延长，SMR在DTN广播式订阅查询系统和洪泛式订阅查询系统中都显示了良好的性能，增强了DTN订阅查询系统的实时性需求。

英文摘要：

DTN is a network model derived from self-organizing wireless networks. It is suitable for actual needs of self-organizing networks because it does not require network＇s full connectivity. How to efficiently transport data to sink node without distinction is being considered in most studies of DTN transport protocols. A DTN＇s merger-based subscription query transport protocol was presented, called SMR, which fully utilizes the processing capacity of the nodes themselves in the system. Experiment results show that the SMR protocol performs better than ER and SWR protocols in both DTN broadcast subscription query system and DTN flooding subscription query system. SMR could be a good candidate to enhance the real-time demand of DTN subscription query system.
