throughout a structure to measure its health. SHM systems have traditionally been built on wired sensor networks, but the great dependability and inexpensive installation and maintenance costs of WSNs have made them a tempting alternative platform. Wired sensor networks are often only practicable for long-term SHM applications where the structure's health is crucial due to their high installation costs.
all-time high. Thousands of new buildings, tunnels, bridges, expressways, and other challenging and complicated structures are being built every day to meet the growing requirements of people as a result of increased growth. The evolution can also be seen in the new materials and building techniques utilised. Because of the increased building of large structures, structural analysis has become a key task, as maintaining the structure's integrity is critical. Traditional methods of structure analysis aren't very useful and don't go far enough. Structural health monitoring (SHM) is a significant advancement in the examination of structures for damage detection and determining the presence of fractures and flaws. The SHM system increases the structure's safety and reliability while also lowering maintenance costs and increasing the structure's usable life. In India, practical uses of this technology are relatively uncommon and lag behind in the civil sector.
The huge cost savings from deploying WSNs for SHM would allow them to be used in critical public and private infrastructure, as well as for applications like short-term structural monitoring. Such systems have the potential to increase the lifespan of many structures by allowing for earlier diagnosis of damage, reducing the expense of routine inspections, and, most importantly, improving public safety.

[1] The author has developed an integrated bridge health monitoring system based on WSN for bridge SHM. This system is comprehensive and practical because it combines a low-level data acquisition platform with a high-level data acquisition data analysis software.
1. INTRODUCTION Continuous structural health monitoring (SHM) systems for aeronautical, mechanical, and civil structures have a lot of promise to become a big part of the damage detection, life assessment, and failure prediction fields. For manufacturers, maintenance teams, and operators, knowing the integrity of in-service structures in real time is critical. SHM is a rising topic of study that merits new and novel techniques. Continuous monitoring necessitates the collecting of data from sensors fixed or implanted in the structure on a regular basis. The collected data is then examined to find any potential defects; also, the monitored system's remaining life can be forecasted.
The platform uses very little power, is flexible and shows scalability to all kind of sensors such as acceleration, temperature, and strain sensor. The network topology uses up to 4 hops of multihop in the experiment. The software enables analysis of multiple types of dynamic response parameters including vibration, acceleration, dynamic displacements and loads or continuous bridge condition monitoring. [2] The main objective of this study is to design and implement a new integrated WSN for impedance SHM system, under which communication and damage detection algorithms have been properly integrated with sensors, microcontrollers and wireless transceivers available on the market.
Wireless Sensor Networks (WSNs) have evolved as a powerful low-cost platform for linking huge networks of sensors over the last decade. Commercial, health, military, and industrial settings have all used these networks. Structural Health Monitoring (SHM) is an example of this type of application, in which sensors are placed
