Application of Wireless Sensor Networks in Post-Disaster Road Monitoring System
2011
The post-disaster road monitoring system provides an interesting application area for wireless sensor networks. After the earthquake, roads are subject to be blocked by landslides. The people require a scalable and low-cost technology for getting real-time dynamic data about road availability because aftershocks occur continuously. Wireless sensor networks are a promising candidate to fulfill these requirements. In this paper the post-disaster road monitoring system solution is put forward. Sensors selection and node configurations, node deployment, multi-sensor information integrated algorithm, and image collection mode are discussed. The multi-sensor information integrated algorithm is adopted to judge the event. And the node deployment is calculated by sensor coverage radius and expectations and redundancy of the system.
