Abstract
This article proposes a novel cost-effective, robust, reliable and flexible infrastructureless IoT multi-hop Wireless Mesh Network (IoT-WMN) for Public Safety and Disaster Response (PSDR). The proposed system is able to auto-detect an Emergency Relief State (ERS) due to a disaster and to auto-configure itself in order to remain up and running, regardless of the disaster nature, to help victims to be timely rescued. To achieve this goal, these networks must be installed quickly and transparently for users, as victims cannot be expected to perform configuration operations or certain multi-hop-enabled software installed on their devices. in case of ERS detection, the system sets up ad hoc connections self-organizing links according to a tandem-based WMN topology and self-configuring access points (APs) for wireless devices (e.g., mobile phones of disaster victims). Devices connected to ad hoc APs become APs in turn, thus extending the network coverage. Available devices of different stockholders (e.g., municipality, first aid organizations, volunteer groups,...) are federated in a whole cooperating system, where each device works at the same time as node, gateway and router.
本文提出了一种新型的经济高效、鲁棒、可靠和灵活的无基础设施物联网多跳无线网状网络(IoT- wmn),用于公共安全和灾难响应(PSDR)。该系统能够自动检测灾难导致的紧急救援状态(ERS),并自动配置自身以保持启动和运行,无论灾难性质如何,以帮助受害者及时获救。为了实现这一目标,这些网络必须快速透明地安装给用户,因为受害者不能期望执行配置操作或在他们的设备上安装某些支持多跳的软件。在检测到ERS的情况下,系统根据基于串联的WMN拓扑结构建立自组织链路,并为无线设备(例如灾民的移动电话)自配置接入点(ap)。连接到ad hoc ap的设备依次成为ap,从而扩展了网络的覆盖范围。不同股东(例如,市政当局、急救组织、志愿者团体等)的可用设备联合在一个完整的合作系统中,其中每个设备同时作为节点、网关和路由器工作。
