Abstract: Internet of Things represents a general concept for the ability of network devices to sense and collect data from the world around us, and then share that data across the Internet where it can be processed and utilized for various interesting purposes. The Internet of Things (IoT) describes a network of physical objects that connect to each other through the internet. Objects or ‘things’ can transfer information wirelessly without requiring human interaction. A ‘thing’ can be any object that can be assigned an IP address and provided with the ability to transfer data over a network. Some also use the term industrial Internet interchangeably with IoT. This refers primarily to commercial applications of IoT technology in the world of manufacturing. The Internet of Things is not limited to industrial applications, however.
