在无线传感器网络、移动ad-hoc网络和延迟/中断容忍网络等无线网络的发展过程中，存储-向前携带（SCF）消息中继模式得到了广泛的关注和研究。SCF网络对于弥补间歇性和范围有限的通信环境的缺陷至关重要，因为它允许移动无线通信节点充当“移动中继节点”。这种中继节点可以存储/携带/处理消息，等待更好的传输机会，最后将消息转发给其他节点。本文首先简要概述了SCF路由，然后研究了两种SCF网络场景。第一个是使用现有的基础设施运输网络（例如，汽车和渡轮）在多个岛屿之间进行大型内容交付，从SCF的角度来看，移动性是不可控的。仿真显示了一种简单的编码技术如何改善基于洪水的SCF。另一种场景是无人机（UAV）的原型系统，用于从空中进行高质量的视频监控，其中从SCF的角度来看，机动性是部分可控的。在这个场景中强调了三个必要的技术——快速链路建立、毫米波通信和多链路的使用。通过这些例子，我们讨论了实际使用基于SCF网络的系统的好处和问题。关键词：店面前移；车载自组网
SUMMARY In the evolution of wireless networks such as wireless sensor networks, mobile ad-hoc networks, and delay/disruption tolerant networks, the Store-Carry-Forward (SCF) message relaying paradigm has been commonly featured and studied with much attention. SCF networking is essential for offsetting the deficiencies of intermittent and range limited communication environments because it allows moving wireless communication nodes to act as “mobile relay nodes”. Such relay nodes can store/carry/process messages, wait for a better opportunity for transmission, and finally forward the messages to other nodes. This paper starts with a short overview of SCF routing and then examines two SCF networking scenarios. The first one deals with large content delivery across multiple islands using existing infrastructural transportation networks (e.g., cars and ferries) in which mobility is uncontrollable from an SCF viewpoint. Simulations show how a simple coding technique can improve flooding-based SCF. The other scenario looks at a prototype system of unmanned aerial vehicle (UAV) for high-quality video surveillance from the sky in which mobility is partially controllable from an SCF viewpoint. Three requisite techniques in this scenario are highlighted – fast link setup, millimeter wave communications, and use of multiple links. Through these examples, we discuss the benefits and issues of the practical use of SCF networking-based systems. key words: store-carry-forward, vehicular ad-hoc networks
