Telecommunication networks play a vital role in all sectors of our society and are especially important during a crisis. Since networks rely on physical infrastructure (e.g., fibers and routers), they are vulnerable to natural disasters, such as earthquakes and floods, or physical attacks, such as an Electromagnetic Pulse (EMP) attack. This project studies the impact of a disaster or attack on the telecommunications infrastructure and develops mechanisms to mitigate their effect. The project considers events that cause a large number of failures in a specific geographical region. It uses probabilistic and geometric failure models that take into account the geography of the network and the attack characteristics. Under these models, techniques to identify the most vulnerable parts of the network are developed. Moreover, tools to provide a-priori protection plan are designed. Finally, restoration algorithms that will improve the resilience of the network are developed. The project will provide a fundamental understanding of the vulnerability of networks to disasters or attacks. It will also provide network algorithms to mitigate the impact of, and recover from, such failures. Therefore, it has the potential to significantly enhance the availability and performance of networks in the event of attacks and disasters. This is crucial for disaster recovery, especially in today?s society that is increasingly reliant on the availability of a communications infrastructure. In addition, the broader impacts will include outreach activities to school children, and incorporation of the results into advanced graduate classes.

电信网络在我们社会的所有部门都起着至关重要的作用，在危机中尤其重要。由于网络依靠物理基础设施（例如纤维和路由器），因此它们容易受到自然灾害的影响，例如地震和洪水，或物理攻击，例如电磁脉冲（EMP）攻击。该项目研究了灾难或攻击对电信基础设施的影响，并开发了减轻其影响的机制。该项目认为在特定地理区域中导致大量故障的事件。它使用概率和几何故障模型，这些模型考虑了网络的地理位置和攻击特征。在这些模型下，开发了识别网络最脆弱部分的技术。此外，设计了提供A-Priori保护计划的工具。最后，开发了将提高网络弹性的恢复算法。该项目将提供对网络对灾难或攻击的脆弱性的基本理解。它还将提供网络算法来减轻此类失败的影响并恢复。因此，在发生攻击和灾难时，它有可能显着提高网络的可用性和性能。这对于灾难恢复至关重要，尤其是在当今的社会中，越来越多地依赖于通信基础设施的可用性。此外，更广泛的影响将包括向学童的外展活动，以及将结果纳入高级研究生班。
