ABSTRACT
The Internet of Things (IoT) refers to a wide spectrum of connected objects both in consumer and industrial usage leveraging systems, sensors, mini processors, reduced energy transmission and Bluetooth, and NB-IoT or LTE-M-based connectivity. The data generated by the IoT is often a huge volume and commonly referred to as big data, which is further transmitted to the internet-based compute and storage facilities referred to as the cloud (private or public) using the IoT gateways. Rich analytics on this data gives credible insights used for further decision-making. In the case of Industrial IoT (IIoT), the process becomes more complex as end-points are governed by proprietary protocols such as Mod-Bus or ProfiNet which are the IoT derivate of the TCP stack. This chapters dwells in detail on all of these concepts and much more including futuristic and evolving technologies and add-on ecosystems such as 3D printing, cryptography, blockchain, and augmented and virtual reality (AR/VR).
