自然灾害可能对通信基础设施造成严重破坏，从而导致受损地区进一步混乱。灾难发生后，大多数灾民都会聚集在疏散地点领取食物和其他必需品。拥有良好的沟通网络对帮助受害者非常重要。在本文中，我们的目标是恢复网络从仍然活着的移动的基站到失去服务的疏散地点，通过使用多跳中继技术。提出了一种基于奖品收集Steiner树的灾后网络容量感知重建方法。所提出的方案的目的是以具有成本效益的方式实现高容量连接率。为了提供更准确的评估结果，我们使用东京地区的真实的疏散现场和基站数据，并利用基于大数据分析的灾后服务可用性模型来评估所提出的方案。
Natural disasters can result in severe damage to communication infrastructure, which leads to further chaos to the damaged area. After the disaster strikes, most of the victims would gather at the evacuation sites for food supplies and other necessities. Having a good communication network is very important to help the victims. In this paper, we aim at recovering the network from the still-alive mobile base stations to the out-of-service evacuation sites by using multi-hop relaying technique. We propose to reconstruct the post-disaster network in a capacity-aware way based on prize collecting Steiner tree. The purpose of the proposed scheme is to achieve high capacity connectivity ratio in a cost efficient way. To provide more accurate evaluation results, we evaluate the proposed scheme by using the real evacuation site and base station data in Tokyo area, and utilizing the big data analysis based post-disaster service availability model.
