摘　　要：DTN网络即容时延容中断网络,主动路由技术是DTN网络中的一项关键技术。根据平流层的实际环境特点,研究DTN主动路由技术在实际应用中存在的问题,并提出了相应的解决方案。最终,提出一种应用于平流层的DTN主动路由技术,即先聚类,后分层,再由无人机巡航的方式进行主动路由,为平流层用户节点提供可靠数据传输。DTN is short of Delay/Disruption Tolerant Network. The active routing is a key network technique in the DTN. According to the actual environment characteristics of stratosphere, the active routing technique of DTN is studied in this paper. A corresponding solution to existent problems is proposed. Finally, an active routing mechanism is presented. It can overcome the limitation of traditional routing mechanism, and support the stratospheric environment. It provides the reliable data transmission for the nodes in stratosphere with clustering, layering and cruising by the uumanned aerial vehicle.
