8.1. Web Application-Based SHS.
A web application-based
interface provides a graphical user interface (GUI) for
monitoring and controlling SHSs. Tese web applications
are mainly based on the Hypertext Transfer Protocol
(HTTP) and Transmission Protocol/Internet Protocol (TCP/
IP). A user can access the sensor reading from the SHS, turn
on/of certain appliances, get a security breach alert, and
check the health condition of the elderly by using these web
applications [95, 113].
8.2. Smartphone Application-Based SHS.
Since the in-
troduction of Android and IOS devices, the usage of
smartphone applications has become widespread. As a re-
sult, SHS researchers are opting more and more for
application-based interfaces [116]. Similar to web applica-
tions, smartphone applications also provide the user with
a GUI for interaction, and the user can get a real-time update
about SHSs. Smartphone applications provide all types of
data and information just like web applications [34, 112].
