SITE: The Simple Internet of Things Enabler for Smart Homes

This thesis presents the Simple Internet of Things Enabler (SITE), a smart home solution that allows users to specify and centrally control IoT smart objects. Unlike most existing systems, SITE supports End-User Development (EUD). It includes features that make the system accessible to users that do not possess a background in Information Technology (IT). Hence, it defines a simple language for the specification of control rules for smart objects. It also provides a user interface to graphically illustrate data received from smart objects.
Furthermore, we present the SITE architecture and describe the components that enable users to define, register, and operate smart objects within a smart home environment. Since deploying applications on the cloud renders many advantages pertaining to data security, robustness, and elasticity of resources, we additionally propose a cloud-based architecture for SITE. In this case, SITE acts as a service hosted on a cloud platform that realizes monitoring and control of a smart home remotely.
Moreover, since most of the objects in any environment are not inherently smart, we propose a framework that affords “everyday” objects the necessary modules to measure and report their state. Hence, users realize the smart objects using a transducer network framework that supports the amalgamation of multiple transducers into a single smart object. To make these objects easily reconfigurable, we apply a plug and play mechanism to enable the clustering of any number of transducers. We propose an algorithm that dynamically detects added and removed transducers from a smart object.
To assess the usability of SITE, we conduct an empirical study involving 20 participants belonging to two user groups: users with technical training (IT users) and users without technical training (Non-IT users). We demonstrate that both user groups can satisfactorily build smart objects and define control rules in a smart home environment using SITE.
