RESIMA: A new WSN based paradigm to assist weak people in indoor environment

This paper deals with the RESIMA architecture developed to assist people in performing daily activity in indoor environment. As respect to solutions presented in the SOTA, RESIMA is a smart multi-parametric assistive system which performs a high resolution monitoring of the user position in the spatial-temporal domain as well as a deep inertial monitoring of the user status, thus assuring a reliable and continuous form of assistance to weak users. The system is based on a Wireless Sensor Network and smart paradigms which extract relevant information from data collected through the multi-sensor architecture. The paper mainly focuses on the multi-sensor system architecture and smart paradigms used to implement user localization. Positioning system accuracy of about 3 cm has been obtained while the system shows good reproducibility and reliability.
