Secure and flexible sleep tracking device communications for integration in Smart Home networks

Abstract

"BEDsense" is a sleep sensor system under development at Zenseri BV. It is designed to integrate into Smart Homes and control lighting, heating and alarms when home residents are in bed. Data from the BEDsense will also be used for sleep analysis providing sleep profiles, quantitative metrics and recommendations to improve sleep quality of users. The objective of this master's thesis is to develop and in part implement a universal plug and play strategy in terms of connecting to the home Wi-Fi network, discovery and data communications. A second objective is to study a system solution whereby BEDsense data can be collected and used for sleep analysis. These objectives take into account the limitations of memory, computing power and data communication bandwidth/availability.

This thesis focuses on defining the communication specifications, implementation of a prototype system, development of a user interface via a Windows and Android app and finally definition of a sleep analysis system.

The result of this thesis is an agreement on the communication protocols, provisioning means (WPS- and AP-mode), SSDP protocol definitions making the BEDsense visible within the network, a user interface app and test tool for provisioning, configuration and diagnostic services in order to test performance. Subsequently, a system is created where raw sensor data is transformed into a format that is suitable for storage and transmission. These results form a first step for Smart Home integration and sleep analysis.
