Literature Survey on Structural Health Monitoring

Structures are playing very important role in our day-to-day life such as dams ,bridges, rail tracks, aircrafts, industrial machineries ,high-rise building and so on. However, the long-term decay of these structures can be caused by unnatural/disaster conditions such as earthquakes, tsunami, winds and hurricanes. In this unfavorable condition constant supply of electric current to the Wireless Sensor Network (WSN) are impossible. So, we are adopting Wireless Rechargeable Sensor Network (WRSN) in Structural Health Monitoring (SHM). Comparing with WSN, WRSN provides sensing and analyzing of structures even during the unfavorable moments. On the same side it overcomes the key challenges like computationally intensive, resource constraints and long-term monitoring. The main issues in our SHM includes network life-time, stability, damage detection, reliability and trade-offs in model which is overcome by multi-scale Wireless Rechargeable Sensor Network with restricted input network activation scheme and the integration of data network activation scheme and the data integration from a heterogeneous sensor array to improve damage detection for low-order models. It helps to improve power efficiency, minimize packet loss and latency and eliminate synchronization issues through the use of a decentralized analysis scheme (i.e.) Cyber Physical System (CPS) approach.
