Talking about the Internet of Thing, commonly referred to as IoT, is endless because the Internet of Things does not have a fixed definition, there is always a discussion whether it comes from our daily lives to things that can be used as devices to facilitate our activities. But we can determine whether a device is part of an IoT or not with the following question: Can the product of a vendor work with products from other vendors? Can a door lock from vendor A communicate with the light switch from vendor B, and what if a user wants to enter the thermostat into part of that communication.
So Internet of Thing (IoT) is a concept where an object has the ability to transfer data over a network without requiring human-to-human or human interaction to a computer. IoT has evolved from the convergence of wireless technology, micro-electromechanical systems (MEMS), and the Internet.
The "A Things" in the Internet of Things can be defined as a subject for people who monitor heart implants, farm animals with biochip transponders, a car that has a built-in sensor to alert the driver when tire pressure is low. So far, IoT is most closely related to machine-to-machine communication (M2M) in manufacturing and electricity, oil and gas. Products are built with M2M communication capabilities which are often referred to as smart or "smart" systems. For example, smart cables, smart meters, smart grid sensors.
Research on IoT is still in the development stage. Therefore, there is no definition of the Internet of Things. Here are some alternative definitions put forward to understand the Internet of Things (IoT), including (id.wikipedia.org):
According to Ashton in 2009 the initial definition of IoT was that the Internet of Things had the potential to change the world as the Internet had done, maybe even better. The statement was taken from the article as follows:
"Today computers and humans are almost completely dependent on the Internet for all information which consists of around 50 petabytes (one petabyte is 1,024 terabytes) of data available on the Internet and was first conceived and created by humans. From the magnetic start, press the record button, take digital pictures or have enough bar codes.
Conventional diagrams from the Internet leave routers the most important part of all. The problem is that people have limited time, attention and accuracy. They all mean it's not very good at capturing various data about things in the real world.
In terms of physical and so is our environment. Ideas and information are important, but many things are important. But today's information technology is very dependent on data that comes from people so that our computers know more about all the ideas of these things "
According to Casagras (Coordinator and support for action for global RFID-related activities and standardization) defines IoT as a global network infrastructure, which connects physical and virtual objects through exploitation of data capture and communication capabilities. Infrastructure consists of existing networks and the internet along with network development. All of this will offer object identification, sensors and connection capabilities as the basis for independent service development and application co-operatives. It is also characterized by a high degree of autonomous data capture, event transfer, network connectivity and interoperability.
