The Internet of Things (IoT, also Cloud of Things or CoT) refers to the interconnection of uniquely identifiable embedded computing like devices within the existing Internet infrastructure.
Typically, IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine communications (M2M) and covers a variety of protocols, domains, and applications. The interconnection of these embedded devices (including smart objects), is expected to usher in automation in nearly all fields, while also enabling advanced applications like a Smart Grid.
Things, in the IoT, can refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, automobiles with built-in sensors, or field operation devices that assist fire-fighters in search and rescue. Current market examples include smart thermostats such as the nest and washer/dryers that utilize wifi for remote monitoring.
