The Internet of Things (IoT) technology has a wide variety of uses, and the use of the Internet of Things is increasing at an increasingly rapid rate. Depending on the different fields of application of the Internet of Things, it operates according to its design/development. But it does not have a standardized working architecture that strictly follows universally. The architecture of IoT depends on its functionality and implementation in different industries. Yet, there is a core process flow upon which the IoT build.

So, here in this article, we will discuss the basic architecture of IoT, H. 4-step IoT architecture.

So, from the picture above, it is clear that there are four layers, which can divide as follows: acquisition, network, data processing, and application.

Acquisition layer

Within this detection layer is sensors, actuators, and devices. These sensors or actuators accept data (physical/environmental parameters), process data, and send data over the network.

Network layer

Internet/network entries and data acquisition systems (DAS) are current in this layer. DAS makes data aggregation and adaptation functions (collecting and combining data, converting analog sensor data to digital data, etc.). Advanced gateways, which primarily open the connection between sensor networks and the Internet, also perform many basic gateway functions such as anti-malware protection and sometimes also filter decisions based on entered data and management services, data, etc.

IT layer

It is the processing unit of the IoT ecosystem. Here the data is analyzed and preprocessed before it sends to the data center. Software applications access the data, often referred to as business applications, where the information is monitored and managed, and other actions also prepare. It is where edge IT, or edge analytics come into play.

Application layer

It is the last layer of the four levels of the IoT architecture. Data centers, or the cloud, are a phase of data management where data is managed and used by end-user applications such as agriculture, healthcare, aerospace, agriculture, defense, etc.

Monitor a variety of “things.”

  • Monitored devices or “things” that support IoT-based digital transformation can take several forms:
  • Devices such as thermometers and accelerometers measure natural properties and generate digital measurement information.
  • Cameras and microphones create video and audio information streams that contain more complex information about the world.
  • Beacons and load sensors also fall under the IoT category. Actuators can take various forms, such as relays that turn devices on or off or indicators that indicate when a device is reporting something unusual.
  • Presence sensors or WiFi detection of personnel entering or leaving can use to monitor location measurements.
  • Production systems such as robots and buffers typically contain built-in sensors that provide indicators of operation and performance on the plans.
  • Vehicles such as airplanes and automobiles contain sensors that provide operational and performance metrics.
