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)
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)
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)
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)
A single elderly, dependent subject was monitored for a period of three months. Data were collected from 12 sensors in his apartment. We investigated new criteria for diagnosing abnormal events with more reliability. Initial results suggested that six diagnostic functions could be achieved using only presence sensors. These were: immobility detection; the(More)
—Today, many network applications require shorter react time. Robotic field is an excellent example of these needs: robot react time has a direct effect on its task's complexity. Here, we propose a full deterministic medium access method for a wireless robotic application. This contribution is based on some low-power wireless personal area networks, like(More)
A research and development innovation project partly funded by the French company EDF was conducted for the advancement of smart homes. The aim is to help elderly to live at home in safe conditions. The experiments were carried out in a long-term setting in Orléans (France). As part of the project, the monitoring system aims to assess daily activity(More)
