Internet of Things Patterns for Devices

Devices are an important part of the Internet of Things. They collect data from their environment with sensors and, based on this data, also act on their environment by using actuators. Many use cases require them to support characteristics such as being cheap, light, small, mobile, energy efficient, or autonomously powered. This creates constraints for available energy sources and leads to different kinds of operating modes. Based on existing terminology and additional examples, we describe these energy constraints and the operation modes in the form of Patterns. These Patterns are interconnected with other Patterns to form an Internet of Things Pattern Language that enables practitioners to find and navigate through proven solutions for their problems at hand.
