The key features of computer networks available for a disaster situation are reliable, fault tolerance, and self‐configurable. Therefore, using a wireless mesh network for disaster prevention and recovery system has gained much attention from the research community in the last decades. In addition, from the practical aspects of the network infrastructures of the disaster system, we should assume the core capabilities such as wireless connectivity in a wide range, ease of use, and low cost so on. In this paper, we propose an interface mode assignment method for reconstructing a route from an isolated router to a gateway (GW) router in a wireless mesh network based on IEEE 802.11 infrastructure mode after a disaster occurrence. The proposed method assigns an adequate mode to each interface in an isolated router to recover the network reachability in a distributed manner. Simulation results show the effectiveness of the proposed method via two different scenarios. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

基于IEEE 802.11 Infrastructure-Mode的无线Mesh网络自重构的接口模式分配方法

可用于灾难情况的计算机网络的关键功能是可靠，容错和可自行配置。因此，在过去的几十年中，将无线网状网络用于灾难预防和恢复系统已经引起了研究界的广泛关注。此外，从灾难系统的网络基础结构的实际方面来看，我们应该承担核心功能，例如广泛的无线连接，易用性和低成本等。在本文中，我们提出了一种接口模式分配方法，用于在灾难发生后基于IEEE 802.11基础结构模式在无线网状网络中重建从隔离路由器到网关（GW）路由器的路由。所提出的方法为隔离路由器中的每个接口分配适当的模式，以分布式方式恢复网络的可达性。仿真结果表明了该方法在两种情况下的有效性。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
