Unleashing the potential of the Internet of Things 3

– Support device diagnosis and automatic reparation.
– Support capability of creating, updating, deleting and retrieving device identifiers and
managing identifier mapping.
– Support device discovery.

– Support capability of grouping devices based on device attributes (such as device type,
device location, etc.).

9.2.2.3 Data processing
The functionalities of data processing are as follows:

– Support capability of data format transformation between different data formats as required
by devices and applications.

– Support capability of aggregating data from devices and applications.
9.2.2.4 Data storage

The functionalities of data storage are as follows:
– Support access rights (e.g., read, write) to data that are stored in the gateway for security
and privacy purposes.
– Support capability of data caching for data from devices and applications.
– Support data synchronization between the gateway and applications, e.g., upload of
collected data from devices to applications, download of configuration management data
from applications to the gateway.
9.2.2.5 Communication management

The functionalities of communication management are as follows:
– Support capability of establishing and managing communications between the gateway and
applications.
– Support selection of the access network (to connect with the communication networks)
according to the communication technologies supported by the gateway (e.g., GPRS,
WCDMA, LTE, etc).

– Support capability of data transferring from applications and devices based on QoS enabled
policies, e.g., priority of data transferring from devices in different network environments.

– Support capability of communication based on device grouping.
9.2.3 Adaptation capabilities group

9.2.3.1 Interface abstraction

The functionalities of interface abstraction are as follows:
– Support interface mapping from abstract interface to specific interfaces supported by
devices and applications. This includes interface mapping for new device interfaces when
new types of devices connect to the gateway.

9.2.3.2 Device adaptation

The functionalities of device adaptation are as follows:
– Support capability of connectivity adaptation for the different types of devices or other
gateways that connect to the gateway.

9.2.3.3 Network adaptation

The functionalities of network adaptation are as follows:
