摘要

多媒体传输系统和协议通常假定多媒体源和消费者之间存在端到端连接，并且传输延迟较低。然而，这两种特性都不能总是在仓促形成的应急响应行动网络中实现。特别是，中断可能会中断端到端的连接，从而无法立即传送多媒体内容。这项工作提出了一个可以在中断的网络中运行的多媒体交付系统，因此可能有助于提高应急响应行动中的态势感知。多媒体传输系统以HTTP自适应流(HAS)为基础，采用HTTP的改进版本，能够在分区网络中传输数据。在现实的应急响应场景中对多媒体传输系统进行了评估。

A multimedia delivery system for delay-/disruption-tolerant networks

Multimedia delivery systems and protocols usually assume end-to-end connections and low delivery delays between multimedia sources and consumers. However, neither of these two properties can always be achieved in hastily formed networks for emergency response operations. In particular, disruptions may break end-to-end connections, which makes it impossible to deliver multimedia content instantly. This work presents a multimedia delivery system that can operate in disrupted networks and hence may help improve the situational awareness in emergency response operations. The multimedia delivery system is based on HTTP adaptive streaming (HAS) and uses a modified version of HTTP which is able to deliver data in partitioned networks. The multimedia delivery system is evaluated in a realistic emergency response scenario.
