在紧急情况下，通信网络经常中断，这可能会使救援行动变得缓慢、风险更大、效率更低。在这种情况下，我们的论文有两个目的：(一)量化此类干扰的严重程度，(二)评估将其降至最低的最佳战略。对于这两项任务，我们利用了一套现实世界的众包跟踪，包括有关全美数千智能手机用户的位置和连接(蜂窝和Wi-Fi)的信息。通过我们的分析，我们发现在人口密集的城市中心启用设备到设备通信非常有益，而在郊区将Wi-Fi接入点纳入安全网络是最佳策略。
Communication networks are often disrupted during emergency situations, which can make relief operations slower, riskier, and less effective. In this context, our paper has the twofold purpose of (i) quantifying how significant such disruptions are, and (ii) evaluating the best strategies to minimize them. For both tasks, we leverage a set of real-world, crowd-sourced traces, including information on the position and connectivity (cellular and Wi-Fi) of thousands of smartphone users across the United States. Through our analysis, we find that enabling device-to-device communications can be extremely beneficial in dense urban centers, while including Wi-Fi access points in the safety network is the best strategy in suburban areas.
