Networking Strategies for Structural Health Monitoring in Wireless Sensor Networks

초록

Structural health monitoring (SHM) systems using wireless sensor networks (WSNs) improve the safety and reliability of civil infrastructures by detecting damages before they reach a critical state. To achieve this, numerous challenges range from software design to hardware design. However, the intrinsic networking requirements for SHM have been overlooked in current SHM design. Therefore, we analyze wireless networking issues to satisfy the equirements of SHM. Then, the state of the art in the networking issues is reviewed including reliable data transfer, time synchronization, and power management. Finally, we discuss opportunities influencing WSN development for SHM in the future.
