Internet of Things

The Internet of Things (IoT) is the network of physical objects embedded with electronics, software and sensors, with network connectivity that allows objects to be sensed and controlled remotely across the Internet.

The IOT World Forum reference model, illustrated, consists of 7 layers.  Data is collected by sensors and systems at the physical layer (Layer 1) and sent via a network, Layer 2, to storage in Layer 4.  In some instances data is processed locally, near the sensor network before being stored which is referred to as Layer 3 “Edge Computing”.  Data sent from layer 1 to layer 4 is event based meaning that data is measured and sent periodically or when a certain event occurs such as the movement of a sensor, in this sense Layers 1 to 4 are often classified as “real time”.  Once the data in stored into a database on the cloud it can be accessed or queried anytime, represented in Layer 5.  In this layer data is also aggregated from various sources of interest to the business or end user.  In Layer 6 the data is presented in a user friendly form, often in the form of a dashboard to enable insights to be derived from the information.  Finally Layer 7 represents the utilisation of the information derived from the data.
