在地震或海啸等灾难时期，救援和恢复工作通常会受到通信故障的阻碍，因为现有的通信基础设施很可能在灾难期间遭到损坏或摧毁。必须迅速建立支持IP语音和视频流等多媒体流量的临时通信基础设施，以支持救援和恢复行动的指挥、控制和通信需求。这类应用需要相对快速和强大的通信链路，而宽带无线技术似乎是一个可行的解决方案。本文研究了两种分层网络解决方案，它们允许救援队和他们的总部之间使用无线网络技术(即WiFi、WiMax和GEO卫星)和多媒体软件应用程序(特别是IP语音)相结合的超远距离传输关键任务多媒体数据，以满足灾难救援通信场景的要求。提出的系统已经在现场进行了实验验证，并通过仿真验证了设计的可扩展性。
During times of calamity, such as an earthquake or tsunami, rescue and recovery efforts are usually hampered by communications failure as the incumbent communications infrastructure has most likely been damaged or destroyed during the disaster. An ad-hoc communications infrastructure, with support for multimedia traffic such as Voice over IP and video- streaming, must be quickly put in place to support the command, control and communication needs of the rescue and recovery operations. Such applications require relatively fast and robust communications links, and broadband wireless technologies appear to be a viable solution. This paper examines two hierarchical network solutions which allow the delivery of such mission-critical multimedia data between rescue teams and their headquarters over extremely long distances using a combination of wireless network technologies (namely, WiFi, WiMax and GEO Satellite) and multimedia software applications (in particular, Voice-over-IP) to meet the requirements of disaster rescue communication scenarios. The proposed system has been validated experimentally in the field as well as using simulations to demonstrate the scalability of the design.
