摘要：Wireless Sensor Networks are becoming relevant technology for Structural Health Monitoring (SHM)applications for easy deployment of sensors than the Wired Sensor Networks. SHM is the process of implementing thedamage detection (health) and characterization strategy for engineering structures (bridges/dams). However, theconstraints e.g., communication distance, energy of WSNs must be considered before their deployment on structures.The faults in the Wireless sensor communication such as errors, unstable connectivity affect the performance of sensorwhile monitoring the health of the structure. In existing system, the sensor location is adjusted according to theengineering and computer science requirements, such adjustments leads to missing of some optimal location. Inproposed system, Critical Middle point SHM (CMSHM) is introduced to make resilient WSN faults. CMSHM checksfor the distance and guaranteed that the WSN for SHM remains connected in the event of faults, thus prolonging theWSN lifetime under connectivity and data delivery constraints.
