In the Internet of Things (IoT), devices have a unique identity and can communicate with each other or take orders. With the Internet of Things, applications can be automated and tasks performed without external intervention. Depending on the scope and technique used, the definitions of the Internet of Things may differ. In general, the term Internet of Things is used for the networking of everyday objects or machines in the industrial environment via the Internet. Devices get a unique identity (address) in the network and are equipped with electronic intelligence. This enables them to communicate over the Internet and perform tasks fully automatically.
The smart devices are often referred to as smart devices. In addition to the possibility of device communication (machine-to-machine communication, M2M), many of the networked objects provide an interface via the Internet, via which the devices can be operated and controlled by a user from anywhere. Distinction between private and industrial applications Basically, the Internet of Things distinguishes between private and industrial applications.
In the private environment, objects of everyday use are mainly networked for a more comfortable and intelligent use. For example, intelligent building automation systems can be installed or devices that contact the user in certain events via the Internet can be installed. In the industrial sector, the main aim is to connect machines and systems in such a way that entire industrial processes can be automated. This makes production processes more efficient and cheaper.
The Internet of Things is an elementary component of the so-called Industry. With the IoT and Industries , the self-organization of industrial processes becomes possible through the direct communication of machines, plants, goods and people. It is no longer necessary to automate individual production steps but entire value chains and make them much more efficient. The Internet and microprocessor technology form the technical foundation of the Internet of Things.
Thanks to increasingly cheaper, smaller and more powerful microprocessors, objects can be equipped with relatively little effort with electronic intelligence. You also receive a wired or wireless interface for connection to the Internet and a clear Internet address. They use these to send or receive their data and commands. As wireless communication technologies, for example, WLAN, Bluetooth or mobile standards such as UMTS and LTE are used. RFID technology (Radio Frequency Identification) plays an important role in the clear identification of goods and goods and their tracking in logistical processes. The RFID systems consist of transponders and networked readers. The transponder is a radio tag attached to the item. This is wirelessly recognized and read by the reader. The networked reader sends the collected data via the web to other communication partners for further processing.
Security is a big aspects in the Internet of Things because the devices are networked with each other on the Internet, they are fundamentally at the risk of external attack or unauthorized use. Abuse scenarios range from unauthorized reading and spying on personal data to running cyber attacks.
