Sensors are a cornerstone of heavy industrial operations. Manufacturing plants and general engineering facilities, such as power plants or shipboard engine rooms, require a high degree of sensing to ensure product quality and/or efficient and safe operation. Wireless sensor networks are a natural fit to meeting the demands of scale, data access and cost. However, the nature and environment of industrial applications presents unique requirements for sensornets. To better understand these challenges, we conducted deployments in two settings: a semiconductor fabrication plant and an oil tanker. The context for the deployments was a condition based maintenance application which monitors machinery vibration to detect/preempt failures.
