In the era of information technology, the elderly and disabled can be monitored with numerous intelligent devices. Sensors can be implanted into their home for continuous mobility assistance and non-obtrusive disease prevention. Modern sensor-embedded houses, or smart houses, cannot only assist people with reduced physical functions but help resolve the(More)
OBJECTIVE Extensive efforts have been made in both academia and industry in the research and development of smart wearable systems (SWS) for health monitoring (HM). Primarily influenced by skyrocketing healthcare costs and supported by recent technological advances in micro- and nanotechnologies, miniaturisation of sensors, and smart fabrics, the continuous(More)
The aim of this paper is to introduce a smart tool for the assessment of the mobility of patient with motor disorders and to evaluate its performance through some initial experiments. These experiments are based on a system which is composed of sensors connected to a Personal Computer (PC) using data acquisition cards and a communication network. The PC(More)
In an ageing world, maintaining good health and independence for as long as possible is essential. Instead of hospitalization or institutionalization, the elderly and disabled can be assisted in their own environment 24h a day with numerous 'smart' devices. The concept of the smart home is a promising and cost-effective way of improving home care for the(More)
Over years, radical changes in engineering technology have taken place due to greatly improved instrumentation, enhanced computing power, new sensors and upgraded transmission mediums making it possible to achieve in the field what once could only be done on laboratory models. In daily life, the use of an active self-testing instrumentation endowed with a(More)
Measurement, control and monitoring systems are increasingly complex and may require various disciplinary skills. Producing such systems requires rigorous design methodology and the right tools. It is with this in mind that the design and formal verification HiLes tool was developed. This methodological design and verification process was used in this work(More)
In this paper, we present the design and the modelling of multi-tier Wireless Sensor Network (WSN) for home application. The proposed solution aims to save energy in a heterogeneous wireless sensor environment. The purpose of this work is to assign intelligent behaviour to each sensor node according to its role in the network in order to increase its(More)
Today's industrial sensor networks require strong reliability and guarantees on messages delivery. These needs are even more important in real time applications like control/command, such as robotic wireless communications where strong temporal constraints are critical. For these reasons, classical random-based Medium Access Control (MAC) protocols present(More)
A multisensor home monitoring system has been developed within a telecare project to help elderly people by observing mobility changes indicative of abnormal events. This paper assesses the motor activity and the relationships between activity measures using the system. The motor activity data (in bed, getting up, getting out, visiting the toilets) are(More)
