Editing Wireless sensor network (section)

====Machine health monitoring====
Wireless sensor networks have been developed for machinery [[condition-based maintenance]] (CBM) as they offer significant cost savings and enable new functionality.<ref>{{cite journal|author=Tiwari, Ankit|display-authors=etal|title=Energy-efficient wireless sensor network design and implementation for condition-based maintenance|journal=ACM Transactions on Sensor Networks |volume=3|pages=1–es|doi=10.1145/1210669.1210670|year=2007|citeseerx=10.1.1.188.8180|s2cid=7278286}}</ref>

Wireless sensors can be placed in locations difficult or impossible to reach with a wired system, such as rotating machinery and untethered vehicles.
