Internet of Things

From Wikipedia, the free encyclopedia

The Internet of Things (IoT, sometimes Internet of Everything) is the network of physical objects or "things" embedded with electronics, software, sensors, and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator and/or other connected devices based on the infrastructure of International Telecommunication Union's Global Standards Initiative.[1] Internet of Things connect physically and remotely by individuals, for both public sector and private sector,[2] in the sense of a computer network grid, of a created electrical device that is in place, with economic benefit and potential usefulness.[3][4][5][6][7] Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Experts estimate that the IoT will consist of almost 50 billion objects by 2020.[8]

The term “Internet of Things” was coined by British entrepreneur Kevin Ashton in 1999.[9] 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.[10] 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,[11] and expanding to the areas such as Smart city.[12][13]

Things, in the IoT, can refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, electric clams in coastal waters,[14]automobiles with built-in sensors, or field operation devices that assist fire-fighters in search and rescue.[15] These devices collect useful data with the help of various existing technologies and then autonomously flow the data between other devices.[16] Current market examples include smart thermostat systems and washer/dryers that utilize Wi-Fi for remote monitoring.

Besides the plethora of new application areas for Internet connected automation to expand into, IoT is also expected to generate large amounts of data from diverse locations that is aggregated very quickly, thereby increasing the need to better index, store and process such data.[17][18]
