Internet of Things (IoT)

To the current individual in the high-speed trend of ICT, you  must have been familiar with the hash-tag (#IoT). If not, you can search for the hash-tag via twitter & read from me
The Internet of Things (IoT) 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 thermostat systems and washer/dryers that utilize wifi for remote monitoring.
 Due to the ubiquitous nature of connected objects in the IoT, an unprecedented number of devices are expected to be connected to the Internet. According to Gartner, there will be nearly 26 billion devices on the Internet of Things by 2020. ABI Research estimates that more than 30 billion devices will be wirelessly connected to the Internet of Things (Internet of Everything) by 2020. 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—83 percent—agreed with the notion that the Internet/Cloud of Things and embedded and wearable computing will have widespread and beneficial effects by 2025. It is, as such, clear that the IoT will consist of a very large number of devices being connected to the Internet.
 Integration with the Internet implies that devices will utilize an IP address as a unique identifier. However, due to the limited address space of IPv4 (which allows for 4.3 billion unique addresses), objects in the IoT will have to use IPv6 to accommodate the extremely large address space required. Objects in the IoT will not only be devices with sensory capabilities, but also provide actuation capabilities (e.g., bulbs or locks controlled over the Internet). To a large extent, the future of the Internet of Things will not be possible without the support of IPv6; and consequently the global adoption of IPv6 in the coming years will be critical for the successful development of the IoT in the future.
 The embedded computing nature of many IoT devices means that low-cost computing platforms are likely to be used.
In fact, to minimize the impact of such devices on the environment and energy consumption, low-power radios are likely to be used for connection to the Internet. Such low-power radios do not use WiFi, or well established Cellular Network technologies, and remain an actively developing research area. However, the IoT will not be composed only of embedded devices, since higher order computing devices will be needed to perform heavier duty tasks (routing, switching, data processing and etc.). Companies such as FreeWave Technologies have developed and manufactured low power wireless data radios (both embedded and standalone) for over 20 years to enable Machine-to-Machine applications for the industrial internet of things.
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 and very high-velocity, thereby increasing the need to better index, store and process such data.
Diverse applications call for different deployment scenarios and requirement, which have usually been handled in a proprietary implementation. However, since the IoT is connected to the Internet, most of the devices comprising IoT services will need to operate utilizing standardized technologies. Prominent standardization bodies, such as the IETF, IPSO Alliance and ETSI, are working on developing protocols, systems, architectures and frameworks to enable the IoT.

Major History
As of 2014 the vision of the Internet of Things has evolved due to a convergence of multiple technologies, ranging from wireless communication to the Internet and from embedded systems to micro-electromechanical systems (MEMS). This means that traditional fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation), and others, all have contributions to enable the Internet of Things (IoT).
The general concept of a network of smart devices has been discussed[by whom?] since at least 1991. In 1994 Reza Raji described the concept in IEEE Spectrum as "[moving] small packets of data to a large set of nodes, so as to integrate and automate everything from home appliances to entire factories".  However, only in 1999 did the field start gathering momentum. Bill Joy envisioned Device to Device (D2D) communication as part of his "Six Webs" framework, presented at the World Economic Forum at Davos in 1999.
Kevin Ashton proposed the term "Internet of Things" in the same year.
In a seminal 2009 article for the RFID Journal, "That 'Internet of Things' Thing", Ashton made the following assessment:
 Today computers—and, therefore, the Internet—are almost wholly dependent on human beings for information. Nearly all of the roughly 50 petabytes (a petabyte is 1,024 terabytes) of data available on the Internet were first captured and created by human beings—by typing, pressing a record button, taking a digital picture, or scanning a bar code. Conventional diagrams of the Internet … leave out the most numerous and important routers of all - people. The problem is, people have limited time, attention and accuracy—all of which means they are not very good at capturing data about things in the real world. And that's a big deal. We're physical, and so is our environment … You can't eat bits, burn them to stay warm or put them in your gas tank. Ideas and information are important, but things matter much more. Yet today's information technology is so dependent on data originated by people that our computers know more about ideas than things. If we had computers that knew everything there was to know about things—using data they gathered without any help from us—we would be able to track and count everything, and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best. The Internet of Things has the potential to change the world, just as the Internet did. Maybe even more so.
—Kevin Ashton, "That 'Internet of Things' Thing", RFID Journal, July 22, 2009
The concept of the Internet of Things first became popular[when?] through the Auto-ID Center at MIT and related market-analysis publications. Radio-frequency identification (RFID) was seen[by whom?] as a prerequisite for the Internet of Things in the early days[when?]. If all objects and people in daily life were equipped with identifiers, computers could manage and inventory them. Besides using RFID, the tagging of things may be achieved through such technologies as near field communication, barcodes, QR codes and digital watermarking.
In its original interpretation,[when?] one of the first consequences of implementing the Internet of Things by equipping all objects in the world with minuscule identifying devices or machine-readable identifiers would be to transform daily life in several positive ways. For instance, instant and ceaseless inventory control would become ubiquitous. A person's ability to interact with objects could be altered remotely based on immediate or present needs, in accordance with existing end-user agreements. For example, such technology could grant motion-picture publishers much more control over their films by better applying copyright restrictions and digital restrictions management, so a customer buying a Blu-ray disc containing a movie could choose to pay a high price and be able to watch the movie for a whole year, pay a moderate price and have the right to watch the movie for a week, or pay a low fee every time she or he watches the movie, similarly to Circuit City's DIVX.
