Fault Tolerant Path Detection in Wireless Mesh Networks for Disaster Notification

Early detection of natural disasters and reliable notification to emergency responders are crucial. However, existing notification systems rely on wired communication networks which have a risk of cable damage due to disaster. To avoid such risks, we argue the necessity of a nationwide wireless mesh network for disaster notification. In this paper, we propose methods for generating notification paths that satisfy fault tolerance, for constructing a wireless mesh network using disaster management equipment in a building. Experimental results show that notification paths can be generated in a short time while keeping the probability of isolated nodes low.
