            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.
