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。
DTN is a network mode1 derived from se1f-organizing wire1ess networks.It is suitab1e for actua1 needs of se1f-organizing networks because it does not require network's fu11 connectivity.How to efficient1y transport data to sink node without distinction is being considered in most studies of DTN transport protoco1s.A DTN's merger-based subscription query transport protoco1 was presented
ca11ed SMR
which fu11y uti1izes the processing capacity of the nodes themse1ves in the system.Experiment resu1ts show that the SMR protoco1 performs better than ER and SWR protoco1s in both DTN broadcast subscription query system and DTN f1ooding subscription query system.SMR cou1d be a good candidate to enhance the rea1-time demand of DTN subscription query system.
