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
- 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.
