Civil structures are large-scale systems and they have wide range of applications, hence safety is the supreme issue that needs to be considered during design process. In order to monitor the health status, operations and to detect the changes in structure that affects the performance, Structural health monitoring (SHM) systems are implemented. Wireless Sensor Networks (WSN) are widely used in SHM applications. Nodes in WSN are prone to errors due to several reasons like depletion of energy, link failure, malicious node etc... To make the SHM resilient to fault, FTSHM (fault-tolerance in SHM) is used. FTSHM deploys a set of backup sensors on identification of repair points in distributed manner. To prolong the WSN lifetime, an energy efficient SHM algorithm, called Destruction- Pointer is used, which runs on each sensor and provides a light-weighted indication of damage in a cluster in a decentralized manner, thus improving the life time of WSN under connectivity and providing guaranteed data delivery with reduced delay in the SHM applications.
