IEEE 802.11 Wireless sensor network for hazard monitoring and mitigation


The objective of this study is developing a new wireless sensor network strategy for analogue measurements to monitor and mitigate natural hazard. The manuscript presents a novel solution for performing analogue measurements during natural hazards through a wireless sensor network that supports mesh topologies. It is based on the Open Link State Routing (OLSR) protocol for routing data through a set of routers supporting every version of the IEEE 802.11 standard (WiFi), from a to ax. In order to overcome every limitation in previous wireless systems, the article presents an overview of existing mesh technologies for microcontroller-based architecture (IEEE 802.15.4) and CPU-based architecture (IEEE 802.11), mainly dedicated to seismic or volcanic hazards. We highlight each of the decisive advantages of the presented technology compared to previous hazard monitoring systems. The new technology purposes multiple topologies, modern network performances and original measurement in real case scenarios, with a same generic solution adaptable to several natural hazards. Topology tests and outdoor experiments were performed in open air; the latter provided analogue measurements in the context of a prescribed vegetation fire and river. These results are discussed in terms of the network latency, user mobility, and measurement uncertainties. Finally, the manuscript concludes with an outlook offered by the novel system for a better understanding of mitigating extreme natural events.
