In 2013 the Global Standards Initiative on Internet of Things defined the IoT as the infrastructure of the information society. 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. Legal scholars suggest to look at Things as a mixture of hardware, software, data. These devices collect data with the help of various existing technologies. IoT is one of the platforms of todays Smart City, the term the Internet of Things was coined by Kevin Ashton of Procter & Gamble, later MITs Auto-ID Center, in 1999. This means that the fields of embedded systems, wireless sensor networks, control systems, automation. Mark Weisers seminal 1991 paper on ubiquitous computing, The Computer of the 21st Century, as well as venues such as UbiComp. In 1994 Reza Raji described the concept in IEEE Spectrum as small packets of data to a set of nodes. Between 1993 and 1996 several companies proposed solutions like Microsofts at Work or Novells NEST, however, only in 1999 did the field start gathering momentum. Bill Joy envisioned Device to Device communication as part of his Six Webs framework, the concept of the Internet of Things became popular in 1999, through the Auto-ID Center at MIT and related market-analysis publications. Radio-frequency identification was seen by Kevin Ashton as a prerequisite for the Internet of things at that point, Ashton prefers the phrase Internet for Things. If all objects and people in life were equipped with identifiers, computers could manage. Besides using RFID, the tagging of things may be achieved through such technologies as near field communication, barcodes, QR codes, for instance, instant and ceaseless inventory control would become ubiquitous. A persons ability to interact with objects could be altered based on immediate or present needs. According to Gartner, Inc. there will be nearly 20.8 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 by 2020. As such, it is clear that the IoT will consist of a large number of devices being connected to the Internet. In an active move to new and emerging technological innovation. The ability to network embedded devices with limited CPU, memory, on the other hand, IoT systems could also be responsible for performing actions, not just sensing things
