The Effective Use Of Wireless Network In Structural Health Monitoring

In recent years,there has been an increasing interest in the adoption of emerging sensing technologies for instrumentation within a variety of structural systems.Structural Health Monitoring(SHM)using Wireless Networks(WNs)has recently become a point of discuss and research interest due to its capability to reduce the costs associated with the installation and maintenance of SHM systems.SHM systems have been used to monitor,identify,analyze and manage critical infrastructure such as bridges,buildings,stadiums and other architectural structure;and has the noumenon to improve structure lifespan and improve public safety.However,there’s a step into the future which is harvesting energy from the immediate environment by using Wireless Sensor Networks(WSNs)during the SHM of different structures.The data collected and received by Wireless Sensor Networks for Structural Health Monitoring are processed in a systematic way to give different Architectural details and description about a building or structure which pose unique network design challenges.T his paper presents a comprehensive survey of the effective use of WNs in SHM by outlining the algorithms used in damage detection and localization,network design,power requirements for these networks and power optimization strategies,outlining network design challenges,various existing and emerging sensing modalities used for SHM and their respective power requirements,outlining different approaches to SHM,limitations and future research directions.Solutions to network design problems such as scalability,time synchronization,sensor placement,and data processing are compared and discussed.This paper also provides a brief summary of real-world deployments and application of WNs for SHM.
