通信系统故障可能会对人类生活和经济活动造成灾难性的损害，因为人们无法及时、便捷地进行通信和提供优质的服务。因此，人们在日常生活中或在恶劣的环境中，为了防止成千上万的人死亡和受伤，交换信息是非常必要的。对恶劣环境中通信系统行为的研究有助于设计或选择能够在具有挑战性的条件下运行的更具弹性的技术。本文回顾了现有的方法，故障的主要原因，以及极端事件期间通信系统的弱点。首先，我们强调了通信系统的重要性，然后我们研究了相关的工作，通信可能会失败，以及这种失败对人类生活的影响，并在极端事件的反应。此外，我们还研究和分析了在极端事件的各个阶段如何使用通信，并根据许多案例研究确定了通信系统可能遭受的主要弱点和限制。最后，我们确定并讨论了相关的属性，要求和建议的通信系统在恶劣的环境中执行一个合适的服务质量，并在具有挑战性的条件下，以减少通信故障的风险。
The failure of communications systems may cause catastrophic damage to human life and economic activities as people are unable to communicate with each other in a timely manner and with a convenient quality of service. Therefore, the exchange of information is more than necessary for people in their everyday life or during harsh environments to prevent the death and injury of thousands of individuals. The study of communications systems behavior in harsh environments helps to design or select more resilient technologies that are capable of operating in challenging conditions. This article reviews existing approaches, major causes of failure, and weaknesses of communications systems during extreme events. First, we highlight the importance of communications systems, and then we examine related works, how communication may fail, and the effect of this failure on human life in general and during extreme events response. Furthermore, we study and analyze how communications are used during various stages of extreme events, and we identify the main weaknesses and limitations that communications systems may suffer based on many case studies. To conclude, we identify and discuss relevant attributes, requirements, and recommendations for communications systems to perform with a suitable quality of service during harsh environments and to reduce risks of communication failure in challenging conditions.
