            This appendix describes some use cases of a gateway for IoT applications.


            I.1     Gateway in home services
            A gateway in home services can connect to electrical equipment and safety equipment through local
            networks and can connect to remote application servers through the communication networks. The
            electrical equipment and safety equipment can be controlled remotely by the gateway. Figure I.1
            shows a use case of a gateway in home services.

                                                                                           Notification

                                   Figure I.1 â€“ Use case of a gateway in home services

            Home monitoring and management applications include:
            â€“       Monitoring of home security remotely (i.e., remote monitoring through web cameras via the
                    TV, laptop or smartphone)

            â€“       Control  of  appliances  (e.g.,  turn  on/off  lights,  sprinklers,  garage  door,  security  alarm,
                    thermostat, pool heater) remotely via a device with a web browser

            â€“       Scheduling of appliances (e;g. scheduling of lights, water heater, alarm system, heat, and
                    more) via automatically created profiles

            In these scenarios, as shown in Figure I.1, the gateway has a very important role.
            The  home  owner  can  configure  the  gateway  to  control  each  of  the  connected  devices.  Control
            functions may be implemented through pre-set rules (time-of-day, threshold or alarm driven, etc.) or
            implemented through commands delivered via a SMS message.
            The  gateway  can  aggregate  the  information  collected  from  multiple  sensors  and  permit  the
            information to be combined in order to provide more advanced services.
            For example, in home security scenarios, the gateway usually integrates the inputs coming from
            different sensors and provides the home owner with a user interface to configure the home security
            system.
