A Review on Railway Infrastructure and Wagon Health Monitoring and Traffic Controlling Using Wireless Sensor Network

Wireless sensor network-based monitoring systems are now widely used for Railway traffic managing and monitoring for early anomaly detection that can cause huge losses for railway system now IoT based designs has paved a new way to build fast and more efficient condition railway infrastructure monitoring systems at remote locations in railway network segments are emerging. Also, the different methods to harvest energy requirements of wireless sensor network in off grid locations are upcoming feature of integrated systems. Recent developments in Smart Phone features and wide availability of GSM network have added extra dimensions to the have increased the speed of the response of detection of anomalies in condition railway monitoring and exchange of information to avert the accidents. This paper briefly surveys the different methodologies which can be integrated for more proficient and solid remote sensor network-based innovation for faster and safer railway operations.
