Figure I.1 – Scenario of the SPSN used for commercial merchant

I.2 SPSN for home services

The SPSN can be used at home, where occupiers can connect and manage IoT devices (e.g., sounder,
freezer, and camera). With the support of an occupier's SPSN, IoT devices in home network can
communicate with remote IoT applications and services through a communication network.
Additionally, IoT devices can interact with local IoT applications hosted on the SPSN. Figure I.2
shows the scenario for SPSN use in the home.

When an occupier returns home carrying his or her SPSN, the device can automatically (or mutually)
discover and connect to domestic IoT devices. Then the occupier can control these devices through
the IoT application hosted on the SPSN. Furthermore, an occupier can leave the SPSN at home and
remotely control his or her domestic IoT devices through the SPSN via communication networks, for
example from an office.
