浮动内容 (FC) 是一种无基础设施的通信范例，基于在地理受限位置和有限时间内对内容片段进行机会性复制。事实上，它不依赖任何基础设施，这使得它对基础设施不可用或出现故障的所有环境都有吸引力。在本文中，我们分析了其在灾难发生后作为支持救援协调和态势感知应用的通信服务的可行性。我们分析了可能发生的灾难情景，特别关注当地情况（我们的例子是冰岛）以及涉及经济和社会利益的灾难子集。我们描述了可用通信网络及其结构的特征，并将一些在发生灾难时可能发挥关键作用的关键因素个体化。具体来说，我们考虑与两种灾难场景相关的两种服务。第一种是态势感知，无需固定通信基础设施的支持。第二种服务是一种无基础设施的社交驾驶应用程序。通过此类应用程序，受灾害影响的地区附近的车辆之间可以交换信息，有助于减轻灾害和危险状况对车辆交通的影响。对于这两种服务，我们描述了使用浮动内容的可能实现。最后，针对这些场景，我们确定了一些阻碍基于 FC 的实际、实际实施的研究问题。
Floating Content (FC) is an infrastructure-less communication paradigm based on opportunistic replication of a piece of content in a geographically constrained location and for a limited amount of time. The fact that it does not rely on any infrastructure makes it appealing for all those settings where infrastructure is not available or malfunctioning. In this paper we analyze its feasibility in the aftermath of a disaster, as a communication service in support of applications for rescue coordination and situational awareness. We analyze the possible scenarios of disaster, with a special focus on the local context (Iceland in our case), and on a subset of disasters which are of economic and social interests. We characterize the available communication network, its structure, and we individuate some criticalities which could play a key role in case of disaster. Specifically, we consider two services, related to two disaster scenarios. A first one is a form of situation awareness, without the support of fixed communication infrastructure. A second service is a form of infrastructure-less social driving application. The exchange of information between vehicles in the vicinity of a region interested by a disaster, enabled by such app, could help mitigate the impact of disasters and hazardous conditions on vehicle traffic. For both services, we describe a possible implementation using Floating Content. Finally, for these scenarios, we identify some research issues which stand in the way of a realistic, practical implementation based on FC.
