Figure I.3 – Scenario for SPSN use for environment monitoring

When environment-monitoring staff wish to check the status of a specific place, they turn on the
monitoring application and the SPSN discovers sensors close to the SPSN with a Bluetooth-equipped
sensor, connects to them and collects data automatically. The SPSN then asks for the temperature,
moisture and water sensor data and displays them as programmed.

In this scenario, the SPSN collects the information from various sensors, processes the data locally to
the required form, and finally uploads all the information to the monitoring centre.

I.4 SPSN for wearable smart devices
Wearable smart devices (e.g., watches, glasses, headbands and belts) are becoming more and more
popular. Generally, wearable smart devices allow the owner to access information in real-time or non-
real-time.
Due to the high mobility of smartphones, SPSN can be the most common tool for owners to access
and manage their wearable smart devices.
An SPSN can be used to connect and manage users' constrained wearable smart devices through
personal communication technologies, such as ZigBee, NFC, Bluetooth, Wi-Fi or USB. Figure I.4
shows the scenario for SPSN use for wearable smart devices.
