Currently, numerous proprietary communication technologies are used by emergency response personnel to ensure uninterrupted coordination and effective situational awareness, especially when the telecommunication infrastructure gets damaged or destroyed. Affected victims and bystanders, however, lack access to such equipment and are thus deprived of information and unable to reach for help.

To ameliorate the situation, this work details a promising networking architecture that capitalizes on beaconing-based technology already available on existing smartphone devices to provide emergency communications. On top of the proposed architecture, intelligent algorithms are developed to support efficient and resilient message exchange for communication and localization among the affected victims; both of which are necessary for prompt and effective response. The paper first provides an analytical performance evaluation of the proposed approach. It then delves into the development and experimentation details that lead to the implementation of a practical application that can be installed and used in time of need. Real-world experiments demonstrate that the proposed algorithms can sustain alert messaging for extended periods of time.

当前，紧急响应人员使用了许多专有的通信技术来确保不间断的协调和有效的态势感知，尤其是在电信基础设施遭到损坏或破坏时。但是，受影响的受害者和旁观者无法获得此类设备，因此被剥夺了信息，无法寻求帮助。

为了改善这种情况，这项工作详细介绍了一种有前途的网络体系结构，该体系结构利用了现有智能手机设备上已经可用的基于信标的技术来提供紧急通信。在提议的体系结构之上，开发了智能算法来支持有效且有弹性的消息交换，以在受影响的受害者之间进行通信和定位。两者对于迅速有效的响应都是必要的。本文首先提供了对所提出方法的分析性能评估。然后，它深入研究了开发和试验的细节，这些细节导致实现可以在需要时安装和使用的实际应用程序。真实世界的实验表明，所提出的算法可以长时间维持警报消息传递。
