Unleashing the potential of the Internet of Things 3
kinds and used in different domains (e.g., power metering in smart home domain, elder people
monitoring in e-health domain, etc.). This group may utilize the capabilities provided by the support
capabilities group.
The support capabilities group provides common capabilities for the gateway to interact with
devices and applications. This group includes the following capabilities:
– Device management, which provides capabilities for managing devices and communicates
device profiles to the gateway itself and to applications.
– Communication management, which provides capabilities for establishing and managing
communication with devices and applications. It includes capabilities for the support of the
communication QoS requirements (e.g., communication delay, packet loss, etc.).
– Data storage, which provides capabilities for permanent and temporary storage of data,
including data collected from devices, gateway configuration data, data from applications,
etc.
– Data processing, which provides capabilities for processing data, including analyzing data,
transforming data formats, encapsulating data based on application protocols and
aggregating data from devices.
– Data dispatching, which provides capabilities for pre-processing data from applications
based on policies and optimizing data dispatching.
The adaptation capabilities group provides capabilities for communicating with devices and
applications and hiding the differences between devices and applications. This group includes the
following capabilities:
– Interface abstraction, which provides an abstract interface supporting basic operations (such
as reading data from a device) to interact with devices and applications and also provides
mapping capability from an abstract interface to specific interfaces supported by devices
and applications.
– Device adaptation, which provides connectivity adaptation for the different types of devices
or other gateways that connect to the gateway.
– Network adaptation, which provides adaptation to different network technologies, including
PHY/MAC layer adaptation between the gateway and the (access portion of the)
communication networks.
The security and management capabilities group provides capabilites for supporting security and
management of the gateway itself.
