8 IoT reference model

Figure 4 shows the IoT reference model. It is composed of four layers as well as management
capabilities and security capabilities which are associated with the four layers.

The four layers are as follows:
– application layer
– service support and application support layer
– network layer

– device layer.

Figure 4 – IoT reference model

8.1 Application layer
The application layer contains IoT applications.

8.2 Service support and application support layer

The service support and application support layer consists of the following two capability
groupings:

– Generic support capabilities: The generic support capabilities are common capabilities
which can be used by different IoT applications, such as data processing or data storage.
These capabilities may be also invoked by specific support capabilities, e.g., to build other
specific support capabilities.
– Specific support capabilities: The specific support capabilities are particular capabilities
which cater for the requirements of diversified applications. In fact, they may consist of
various detailed capability groupings, in order to provide different support functions to
different IoT applications.
