Opportunistic communications present a promising solution for disaster network recovery in emergency situations such as hurricanes, earthquakes, and floods, where infrastructure might be destroyed. Some recent works in the literature have proposed opportunistic-based disaster recovery solutions, but they have omitted the consideration of mobile devices that come with different network technologies and various initial energy levels. This work presents COPE, an energy-aware ooperative portunistic alrt diffusion scheme for trapped survivors to use during disaster scenarios to report their position and ease their rescue operation. It aims to maintain mobile devices functional for as long as possible for maximum network coverage until reaching proximate rescuers. COPE deals with mobile devices that come with an assortment of networks and aims to perform systematic network interface selection. Furthermore, it considers mobile devices with various energy levels and allows low-energy nodes to hold their charge for longer time with the support of high-energy nodes. A proof-of-concept implementation has been performed to study the doability and efficiency of COPE, and to highlight the lessons learned.
机会主义通信为灾难情况下的网络恢复提供了有前途的解决方案，例如在飓风、地震和洪水等情况下，基础设施可能会被破坏。文献中的一些最新研究提出了基于机会主义的灾难恢复解决方案，但它们忽略了考虑带有不同网络技术和各种初始能量水平的移动设备。这项工作提出了 COPE，这是一种节能合作机会主义警报扩散方案，用于被困幸存者在灾难场景中报告他们的位置并简化救援行动。它旨在使移动设备尽可能长时间地保持功能，以实现最大的网络覆盖范围，直到接近救援人员。COPE 处理带有各种网络的移动设备，并旨在进行系统的网络接口选择。此外，它考虑了具有不同能量水平的移动设备，并允许低能量节点在高能量节点的支持下保持更长时间的充电。已经进行了概念验证实现，以研究 COPE 的可行性和效率，并突出所学到的经验。
