According to the de nition of Wikipedia “ e Internet of ings is the network of physical objects or things embedded with electron- ics, so ware, sensors and connec- tivity to enable it to achieve greater value and service by exchanging data with the manufacturer, opera- tor and/or other connected devices. Each thing is uniquely identi able through its embedded computing system but is able to interoperate within the existing Internet infra- structure.” e Internet of ings is by another de nition “a group of physical objects with embedded sensor technology that communi- cates an internal state or external environments to a network”. According to Gartner, there will be nearly 26 billion devices on the Inter- net of ings by 2020. ABI Research estimates that more than 30 billion devices will be wirelessly connected to the Internet of ings (Internet of Everything) by 2020. As per a recent survey and study done by Pew Research Internet Project, a large majority of the technology experts and engaged Internet users who responded agreed with the notion that the Internet/Cloud of ings, embedded and wearable computing will have widespread and bene cial e ects by 2025. It is, as such clear that the IoT will consist of a very large number of devices being connected to the Internet. What also means that IoT will creates nearly endless growth opportunities for companies in the electronics, IT, and so ware indus- tries. e embedded computing nature of many IoT devices means that low-cost computing platforms are likely to be used. ings, 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, automobiles with built-in sensors, or eld operation devices that assist re- ghters in search and rescue. ese devices collect useful data with the help of various existing technol- ogies and then autonomously ow the data between other devices. 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 con- nected 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 pro- cess such data. What also implies that the IoT goes far beyond the traditional embedded technology e Internet of ings has already evolved due to a convergence of multiple technologies, ranging from wireless communication to the Internet and from embedded systems to micro-electromechanical systems (MEMS). is means that the traditional elds of embedded systems, wireless sensor networks, control systems, automation (including home and building automa- tion), and others all contribute to enabling the Internet of ings. To keep you up to date with the challenges but also possibilities of the IoT we decided to focus this issue upon this topic.
