Effective applications of IoT (Internet of Things) for disaster prevention are highly expected. In particular, in applications for flood disaster prevention, an early warning of the flash flood caused by locally heavy rain is required as well as a flood impact analysis based on water level and rainfall monitoring in the whole drainage basin. However, in a conventional server-centric IoT system, an increase of network load and a delay of feedback control has become one of the most critical issues. Therefore, it is difficult to apply the IoT system to applications of flood disaster prevention, in which both a real-time flood alert and a flood impact analysis are required. In this paper, we propose a distributed cooperative IoT system to solve such problems, and make an attempt to apply the proposed system to applications for flood disaster prevention. This proposed system provides an event-driven data collection mechanism for efficient data collection in low-bandwidth networks on the Never Die Network to achieve disaster tolerance of the access network. In addition, a rule-based autonomous control mechanism as the edge computing in the IoT gateway for a real-time flood alert is offered. In order to evaluate the effectiveness of our proposed method, we developed a prototype system and conducted a field trial in Quang Nam Province, Vietnam. As the result of our evaluation, we have confirmed that up to 1/20, the proposed method can reduce the network load for flood monitoring, and can issue the flood warning at proper timing.
