Wireless Sensor Networks for Condition Monitoring in the Railway Industry: A Survey

In the range of recent years, sensing technologies has expanded widely, whereas sensor devices have become cheaper. This led to rapid expansion in condition monitoring of systems, structures, vehicles, and machinery that are using sensors. Wireless sensor networks can now be used for monitoring the railway infrastructure such as bridges, rail tracks, track beds, and many track equipment along with vehicle health monitoring such as chassis, bogies, wheels and wagons. The wireless sensors network technology for monitoring in the railway industry is used for analyzing systems, structures, vehicles, and machinery. Main focus is on practical engineering solutions, identification of sensor configurations and network topologies.
