Application-Oriented Sensor Network Architecture for Dependable Structural Health Monitoring

—The applicability of wireless sensor networks (WSNs) to data-intensive structural health monitoring (SHM) is being heavily studied recently by the computer science domain. The aim is to monitor complex events (e.g., damage, crack) in structures (e.g., a high-rise building, a long-span bridge), which is usually carried out by civil/structural engineers. However, regarding methods from engineering domains, detection of such events directly over large structures in a centralized manner is extremely costly due to severe resource constraints of WSNs. Although there exist network organization or grouping algorithms (e.g., clustering) developed in distributed manners, they still suffer greatly from high resource usage and a lack of dependability (in terms of ability/quality of monitoring and low false alarm rate). We discover that the dependability is greatly affected by such grouping schemes, as they do not satisfy application-specific aspects. We present an SHM application oriented netw...
