论文摘要
在本文中，我们提出了一个新的三维（3D）网络体系结构，该架构具有集成的空中和地面基站（BSS），以供快速降水后通信恢复。通过利用其各自的响应时间，覆盖面积和操作持续时间的优势，提议的网络是高度异质性的，由持续的地面BS，地面车辆安装的BSS，下降的BS和飞行BS组成。 To reflect the importance of swift communication recovery and the dynamics of coverage area in post-disaster scenarios, we propose a new performance metric called ``time-weighted coverage}", which is an integration of the achieved communication coverage area multiplied with a weighting function over time. By choosing different weighting functions, the network deployment can be designed to achieve tradeoffs between the ``swift communication recovery" and ``stable communication coverage".仿真结果表明，拟议的综合空中和地面网络具有很高的实施灵活性，并且与常规方法相比，它可以显着增强通信覆盖率。
In this paper, we propose a new three dimensional (3D) networking architecture with integrated aerial and ground base stations (BSs) for swift post-disaster communication recovery. By exploiting their respective advantages in terms of response time, coverage area, and operational duration, the proposed network is highly heterogeneous, consisting of sustained ground BSs, ground-vehicle mounted BSs, dropping-off BSs and flying BSs. To reflect the importance of swift communication recovery and the dynamics of coverage area in post-disaster scenarios, we propose a new performance metric called ``time-weighted coverage}", which is an integration of the achieved communication coverage area multiplied with a weighting function over time. By choosing different weighting functions, the network deployment can be designed to achieve tradeoffs between the ``swift communication recovery" and ``stable communication coverage". Simulation results show that the proposed integrated aerial and ground network has high implementation flexibility and it can significantly enhance the communication coverage compared with the conventional approaches.
