Types of IoT Connections

An IoT system has a three level architecture devices. The data moves between these levels. So, it needs to provide the connection on these levels. Three level devices are

IoT System Architecture- Types of IoT Connections

  • Level 1 : Publisher Devices
  • Level 2: Gateways or Broker Devices
  • Level 3: Data system or Cloud Devices

Lets explain the Types of IoT Connections 

1. Device to device (D2D) Connection

In IoT, the smart devices (i.e. sensors) at publisher ends can direct communicate with each other when they need to share information without intermediates (i.e. broker).

This technique is used in robots system, so that components can coordinate and perform action more efficiently.

2. Device to Gateway Connection

 Communications between devices (i.e. sensors) and gateway is directly possible. Where, Gateways are more powerful devices than sensors.

Gateways get data from sensors and route it to the relevant data system.

3. Gateway to Data systems

Data systems get data from gateways and analyze this data, if there exist any problems in data then data systems return this data back to sending source (i.e. send to gateway and gateway send back to sensor).

4. Between Data Systems or Cloud

Data can also transfer within data systems or clouds. For this purpose some Protocols are used to achieve have high availability of data and reliable recovery as well.
